calls keep going in and out despite good coverage - T-Mobile Samsung Galaxy S8+ Questions & Answers

Hello just switched back to t mobile and have a question..have an unlock galaxy s8+ with t mobile firmware and when doing a phone call, myself , as well as the person I'm speaking with, the volume goes in and out despite the fact I have more then adequate service(-100dbm b4). Never drop a call just lose volume..Called t mobile and they have no idea. If I use WiFi calling I don't have the issue. Don't have option to turn off volte being in mostly band 12 only areas so I wouldn't be able to receive calls. Hard having a conversation when you miss seconds at a time of the conversation..tried reflashing firmware with odin as well as a factory reset. Do notice this phone switches between b4 and b12 really frequently despite the fact it isn't needed at my house as both have fine coverage and b4 rarely goes under -105dbm... Any advice?

Is your sim card new? If not I'd start with replacing that. What apn settings are you using? I believe your phone should drop to HSPA+ on a phone call if you have volte off , well mine does anyways and I'm on similar bands but I have ATT as a carrier.

If I turn volte off I wouldn't be able to receive calls, majority of my area is lte only. Just got a sim 1 week ago when I switched back over to t mobile..i noticed that It happens while phone is changing between band 4 and band 12 which it does at the very least once every minute so I disabled band 4 and it seems to not do it now which stinks but it's not a deal breaker as phone still works fine and data speeds are still high enough that it's not a problem just weird

LTE only, I find that hard to believe as most lower grade and mid grade phones don't even have the option for volte but whatever, glad ya got it partially figured out. I would try flashing different basebands aka radio aka modem aka CP lol and see of that fixes the issue.

If I remember correctly any baseband will work except Verizon ones as they are only one that blocks band 12 right? Hopefully find some odin flashable modems online so I don't have to spend forever downloading whole package off Sam mobile. I grabbed latest 955u1 t mobile firmware when I switched from Verizon last week bc phone wouldn't work or update from coming from Verizon for some odd reason

They're all literally the same CP/modem for the u and u1 models, so when changing modems you actually have to flash different build numbers not just different carriers modems with the same build number cause they're all the same lol, aka multi-csc

It's definitely when the phone changes bands, which I still don't get why it's so constant. Played around again tonight and would switch from -100dbm band 4, call would cut out as I switched to -92dbm band 12 then seconds later back to b4 to where it would cut out again. Fix for me is to keep band 4 disabled but then when I go to city I'm screwed bc parts don't have b12 only b4 and I have to go into dialer and re enable it..it. shouldn't cut out, my pixel never had this issue or nexus 6. Idk what to do about this

Using T-Mo SGH-T989 on Mobilicity in Canada, a few questions..

I wonder if anybody is using this phone in Mobi here in Canada, a friend of mine got one and the first thing we noticed was that it takes FOREVER to pick the signal, even u do a manual search is painfully slow to stick to Mobi's network, also the Wifi spot is locked, and so we wonder if anybody knows a way to work around these issues without rooting (at the moment !!!).
Thanks for any input!
Btw, the phone is great, thin, light, no way that crappy mapple mockup will be even close, I mean, it does even come with Si....I mean Voice command, which works amazing!
I don't think there's another radio out yet so, i think the radio searching issue you're having isn't fixable?
I haven't heard anyone complain about the signal search so maybe it's your area or something with your particular phone. Try setting it to WCDMA preferred/only. Also, call into Wind and ask for a network reset.
Also, it seems like the wifi-spot is locked down by the t-mobile ROM. I doubt there's any fix for that other than rooting and installing a non-crippled ROM. I stand to be corrected though as I have yet to get mine in.
I know on mine when I do a Factory Reset it does take a minute or two to find the Mobilicity signal, but then it locks on, and is fine when I restart the phone. No work around for the Wifi Tethering unless you root and freeze the Tethering Manager. Sorry.
it works, i'm using it on Wind as you can see
just set the phone to look for WCDMA only as mentioned above, and it will bypass scanning the Rogers, Bell, Telus signal
so you get the Wind and Mobi towers to show up quickly that way
Funny you have the same problem as couple of other guys here (including me):
http://www.howardforums.com/showthr...-S2x-unlocked-Wont-find-network-automatically
My response remains the same:
It's definitely a problem with Mobilicity not your phone. It happens to me too when I boot up the phone it says "No Service" even though I previously registered with Mobilicity network and phone setting is set to register automatically. Don't worry. Boot up the phone, do nothing and wait for 2-3 minutes and see what happens. I usually have to wait 1 minute or so for the phone to auto-register to Mobilicity, not instant.
Also, in your mobile settings, set it to "WCDMA only" instead of the default "GSM / WCDMA auto" because Mobilicity uses WCDMA bands only. It may speed some things up.
Also, if you want to speed things up even more, go to your dialer, dial *#*#2263#*#*, select "WCDMA Band Preference", and then select "WCDMA 1700" so that the phone looks by default in the 1700 band (the band the Mobilicity uses exclusively).

This is not true.
You can root your phone, use Titanium Backup (paid version) to freeze the system app called "Tethering Manager", after that you can do wifi-hotspot with no problem. T-Mobile uses that software to block this feature.

this is interesting
in WIND i do not have that problem
i power on the phone and it automatically picks up the WIND tower by itself during boot time
so by the time you see the lock screen, it already says WIND Home

In the (Howard Forum) thread that I linked to, a lot of people are having this problem with registering this phone with Mobilicity. And I can personally vouch for it that every time phone boots up it takes an additional 2 minutes before you see Mobilicity.
Thx guys, so I was rt about switching the AWS setting, still it bothers me, in any case and in regards to the Wifi hotspot, what about after installing a ROM, does it stay locked or the app becomes the standard manager for the Wifi hotspot?, I wish I could rewrite the app on the stock ROM but I don't really know how to get into that...

My SGS2x works fine with Mobilicity, been using it with them since the 30th.
wifi tethering worked from day 1 using the stock telus install. I'm now using several custom ROMs, and overall I'm really happy with the phone on mobilicity. their 3g internet leaves lots to be desired though, perhaps it will improve, but it is an unlimited carrier.

He was asking for a non-root solution.....Glad there's another way out there using root. But I think if you root the phone, you mind as well throw another ROM on there. Removes all the bloatware as well.

There's a stripped down version of the stock ROM. Never tried it but maybe that will work. You should just use one of those custom roms if you're going to root it. They have tweaks and other whatnots that improve your phone's performance. Once you go custom, you don't want to go back to stock.

The issue isn't cell towers, the issue is back end internet, after the IP transmission gets through their cell network to whatever centre they use, the internet connection to that that all of Toronto shares it ****ty and can't keep up. It's not a single overloaded tower that's the issue, as you can see by doing constant speed tests while roaming around.
Backend internet connections are expensive, especially the bandwidth on them. Small carrier can't afford to keep up to it's unlimited bandwidth demands.

Well, this is not rooted yet so that's a huge difference since ur phone will for sure include modifications to the radio, in all (I just figured it) is about Samsung, I have a N8 and a NS, compared the 2 with the SMGS2 (T989) and there is a thing in common between the NS and the T989, getting signal from cold boot or out of dead spots is a pain, my N8 picks the signal almost immediately, on the NS running stock it takes a good 2 to 3 mins (or more if out of cold boot) to get signal but the NS running MIUI makes things faster, I presume and since the stock SMGS2 takes a long time (like the NS) the same will happen when u run the phone with a modded ROM, it will pick signal faster.
So I guess it's all about rooting

I agree with the backend connection. But I think it's a bit of both. Some areas don't have as many cell towers as others. (in my area, i only have two) So I have a feeling it's both rather than just the backend.
Hopefully, they have a good new subs-to-upgrade interval so the speeds will get better.
well, regarding the nexus S
a lot of people in WIND also complains that it always stays in "emergency mode calls only, blah blah blah" basically unable to attach itself to the network.
i seldomly get that on my Nexus S, but that's probably because it's customized
but on the T989, i don't have that problem even in stock
so that's actually very nice

That reinforce my statement, is not really the network but mostly the way Samsung works the radios on their phones on the 1700 Mhz freq or at least for us, don't know in the US.
My NS running stock is a pain, modded works nicely, takes a bit longer than my Nokia but gets the network faster than running stock Android, I bet the same happens with the T989.
I am currently on Mobilicity in Vancouver with a crappy cheap phone and it has a hell of a time getting reception on the network. I live in East Van near victoria and I get reception in only 1 room in my place. I am planning on getting the Telus GS2X in a couple of weeks. Would this help my problem? Can anyone who lives in Vancouver and has the GS2X comment on his/her reception in east van?
Thanks alot.

a new phone might not help if the tower is physically too far from your location
however a good phone with good reception could improve your problem
the only way to find out is to try the phone in your house and see if it works for you
Does anyone know the best place to buy this phone and have it shipped to usa. I know tmobile sells the phone but if I use a tmobile branded android phone they up the cost of my service.
If u want the phone not branded to T-Mo then u'll have to get the Telus version sine it comes with no T-Mo stuff, I don't know of this model to be able factory unlocked
On the other hand I have a couple of new questions:
1> Is there a way to fix/access the MMS?, on Mobi I'm getting errors when receiving MMS, the pixs come all blurry.
2> Any way to enable the Wifi Tethering?, using the T-Mo model is just impossible unless u have the T-Mo sim which is not the case and I haven't seen any of the existing ROM's addressing the issue (sorry if I missed the part, so pls let me know if it's fixed )
Thx
1) check the apn settings and match it to the mobilicity ones. Head over to hofo and there's a thread about it
2) you need to root your phone &, put a custom rom on it. There's another way of disabling a process but I suggest the former

Learnt something about Canadian LTE from a buddy who works for a carrier here

So I was enjoying a cigar with a buddy who is a field tech for a Canadian carrier (not mine rogers, but another one) when we got on the topic of a samsung tablet work issued him.
He said he uses it to troubleshoot LTE issues they've been having.
Basicly the device loses LTE and either goes into "no service" or get's stuck in HSPA+.
I freaked because i've noticed the same issue, but thought it was related to CM10 running on my phone.
Apparently they discovered it has to do with they're infrastructure. The phone loses LTE, tries to re-negotiate,gets rejected, and stops trying.
They're work around is to get firmware updates to get the devices (he didn't mention which ones) to re-negotiate a second (or third time) where it almost always goes through.
I just reboot or bounce air plane mode and it often works.
Just figured people might find that interesting.

Bell has had the same issue (for a while), I haven't received any calls about it recently but also didn't receive an email about it being resolved but it appears so. Our temporary resolution for it was to just keep it at H+ for the time being
Found where I posted about it here

When I bought my S3 at the Bell store here in Québec city a few weeks ago, the salesmen insisted on NOT giving me a LTE sim card.
What he told me conquers with what you are describing.
I accepted is suggestion and got a H+ micro sim.
Since then, I returned to the store to get a LTE sim card and I did encounter the issue once or twice.
I am now forcing my phone to remain on H+ at best via Settings > Wireless & networks > Mobile networks > Network mode.
In the greater HRM (Halifax/Dartmouth/Bedford) we have a pretty good LTE footprint according to the Rogers website, but my S3 is constantly reconnecting. I can tell because every time it drops LTE, my visual voicemail app will notify that it has no service.
I turned LTE off because it was just hammering my battery. I could barely make it through a 10 hour work day with little to no usage if I leave LTE on, and I'm supposedly in the middle of the service area.

Off topic: CM10 has awesome battery life with LTE i find
I first read about LTE causing loss of service several months ago. I returned my first SIII because of it and the replacement phone would also loose service randomly. So now if I want to be assured that my phone is working when I really need it to, I have to disable LTE. Seems like more people need to know this since for some people it is important to know that your phone hasn't just decided to go into NO SERVICE mode without warning.
I'm told service providers were, until recently, strongly denying there is any such problem with LTE. It wasn't until the iphone5 came out with the same issue that this became a real problem for customer service.

Not sure if this is the same issue, but I sometimes receive a "not registered on network" or "sim not registered" when phone switches from LTE to 4G or comes back after being in a no service area.
A tech calls me once a week to track the issue and he told me last week they put out a fix for eastern canada and will soon do the same out west if it works. This is Telus by the way.
If you are running into what I mentioned all you have to do is switch to GSM/HSPA Auto mode under - settings/more settings/mobile network/network mode.
Of course you won't have LTE but its a reliable temp solution if you require consistent service.
MTS LTE
I've heard similar from MTS about their LTE!
My Galaxy S3 works fine on LTE, but my brother's S2 LTE never seems to display LTE on the screen, just says 4G all the time, yet speed test results indicate it really IS LTE! The first 2 weeks, his phone kept dropping to NO SERVICE randomly, but more often than not! We swapped out the LTE SIM on day 2 since the first seemed to be defective. After that, I updated the S2 to the latest release OS which seemed to have remove SOME of the issues.
From what I've heard, the LTE towers need the phone to be quiet on network activity for 20 seconds or so before it will attempt to jump back onto LTE. The S3, being much faster, doesn't seem to have issues flipping around as it needs. I'm told they are deciding which software/firmware to upgrade their towers too which will hopefully happen early 2013!
So I'm wondering if this might be the same issue with other carriers, where the problem is ACTUALLY with the towers and not devices?!

Not that stupid as I, like I said, did experience the issue since I got my LTE sim card.
But to answer your question, no I did not have to pay for the new sim card.
I've done the same. I find "4G" fast enough for the most part, so I just leave LTE off for the gain in battery life.
Also in Halifax I might add!

LTE always reverting to 3G/H/H+ on ALL custom and all stock roms

I had LTE for around a month, then out of nowhere, no updates, nothing it disappeared, it's been gone for almost 2 weeks now.
My carrier (O2-UK) says there is no issue, I have literally no idea, I am almost certain it's just Oneplus phones.. but anyone have any info?
As I said, I've tried custom ROM, I've tried all the stock roms clean flashed.

I've tried all roms, all OOS versions. Same issue.
No one else has this issue?! Saw a few on google but no fixes...
I can say that my phone often sticks to edge when I disable the wifi, it won't switch to 3g/4g unless I enable/disable it. I believe this was not the case with oos 3.2.1, with which my phone came with (only have it for a week now). This also happens with CM13. I think there was a update to the radio in the last oos update, so this might be the reason.
I am currently on OxygenOs 3.2.4 and my Lte seems to work properly. I tested it on a 4g area for about an hour or more and lte sticks with no drop to 3g. I will test it more and report back.

I used to have solid good 4G here, now I don't no matter what I do. It isn't a network issue either
Did you double check your data SIM card is set to LTE? I had that setting change to 3g through a weird mix of circumstances. Was miffed I wasn't getting 4g and it turned out my SIM was set to 3g max.

please fix this 1+ we all having hard time with this issue
my 1+3 never stays on 3g or LTE always go back to 2g
Silly suggestion, but are you on the correct APN? My oneplus initially connected on the incorrect APN for my carrier and I wasn't getting LTE, but 3G/H. Once I corrected it, my LTE was constant in the places it should have been.
Works fine for me you probably just getting a stronger h+ signal and it's jumping between mast's

That would make no sense. I had LTE for a solid month sat right at this desk, now, none.
Where I am in the UK we have loads of cell towers around me and it's always jumping about. There is an app that lets you pick what cell tower you want to use, I have forgotten it's name but might be worth a look. Or could be they doing work in your area. Sorry can not think what else it could be
The oneplus 3 and oneplus 2 just don't like LTE, they will find any reason to go to H+/3
Same issue
I am on Three UK, have came from a Galaxy S7 Edge, and that got constant LTE in most areas, now my phone seems to prefer H+ a LOT more than LTE, reverting to it whenever it can, not great, OnePlus really needs to address this issue, wouldn't mind so much if LTE in my area wasn't 75Mbps, compared to 10Mbps on H+

Same issue, same carrier, same frustration
Put me down for the same issue. With faster battery drain on 3.2.4, as well as random complete "no service" signal loss, for maybe 5 seconds. It's annoying as sin, and very disappointing. OnePlus at least is aware of the issue:

Fix
Have found no fix, have reverted to S7 edge, has MUCH better LTE and more reliable signal overall.

T-Mobile user, Can't receive phone calls, caller says they go straight to voicemail

Hello everyone.
I'm new here and this is my newest phone purchase after weeks and weeks of research I decided to purchase this phone. However I'm having one big problem. I cannot receive phone calls using the phone. However I can send text messages which is strange and when I try to talk to someone it switches to 2G for no real reason too.
It's fully updated and completely stock in fact just purchased three days ago. I'm wondering what I could do so I can get this thing working again. I have 30 days to return this thing, and I rather not because its a rather good phone and I like it a lot but if I can't get it to receive phone calls then I have to return it.
please help anyone.

Try installing the t-mobile visual voicemail app, there maybe settings in there you can adjust, only if your U.S though.

Alright I'll try and install the T-mobile visual voicemail app and see what is good
APN settings yes? I have tried that and tried inputting a manual one and even the ones on there which has three types of T-mobile settings
I'm not an expert on this but I have been looking for info on this for a while before I buy an A2 Lite to use on T-Mobile and I believe this post by a T-Mobile MVNO customer service rep may answer your question
The TLDR is that T-Mobile strictly uses band 12 for all VoLTE calls and if the phone doesn't support band 12/VoLTE T-Mobile forces it to use 2G for calls and texts. In some areas where the spectrum has been refarmed and there are a lot of 2G users your incoming call will time out before the tower finishes searching for you on VoLTE and ultimately tries to connect you to 2G, resulting in your phone not actually ringing.
This would also explain why there are no issues with texts, since they don't time out like an incoming call. Apparently there is no solution to this if you live in certain areas and use T-Mobile, and it will continue to get worse as spectrum is refarmed.
Sorry for the delay -- I'm technically off today. I saw you question and just had to pop in and answer, because I have a complete answer for you. Your issue is band compatibility, specifically the lack of Band 12. Let me explain:
For years and years, T-Mobile sent all their calls over the legacy 2G network on 1900MHz. Every call and text message went over this frequency, and all T-Mobile phones still support it for backwards compatibility.
Then, T-Mobile launched Voice over LTE, or VoLTE. But, they made the stipulation that VoLTE would only ever work on LTE Band 12. That means that any phone that didn't specifically have Band 12 LTE would still have to use the 2G 1900MHz frequency to send all calls and text messages. Any phone that did support Band 12 could use VoLTE and would send all their calls and texts through that VoLTE Band 12 connection.
That's not really a problem for most people, as T-Mobile's 2G network is still live in all their markets. These phones will connect to the LTE network for all data, but all their calls and texts go over that 2G connection.
Enter the problem: Spectrum crunch. Spectrum in the US is a limited resource. That's why the auctions always for it always go for millions of dollars for tiny portions. T-Mobile (and by extension, all its MVNOs, as we have no power over how they build their network) wants to make LTE the new standard, and push into 5G. In order to do that, they need to launch LTE in more places, and feed more devices than ever. They only have so much spectrum, so they reallocate what they already have to the new technology.
This is already happening with 3G. 2G is, again, just being kept around for backwards compatibility. They take the sectors that broadcast 3G (and 2G) and make them smaller and smaller, so the rest of the room can be used for LTE to service more devices faster. It makes business sense.
The process is called "re-farming" spectrum, and a quick Google search quickly becomes a rabbit hole as you find other people in your circumstance. They put the disused services on tiny little slivers of spectrum, some as small as 5MHz, which without getting too technical, is tiny.
If you happen to be unlucky enough live in an area where they're re-farming 2G spectrum to LTE, and your phone doesn't support VoLTE on Band 12, you're effectively fighting all the other T-Mobile (really any carrier, but for arguments' sake) customers whose devices also need to connect to that 2G network
Add enough people, and you get the problem you're having. A call comes into the network, and the towers go to work trying to find you. First, they try VoLTE, and don't find you there. Then they try the old 2G network, but there's like 200 other people in your area that are connected to that one tower, so it has to fight through them all to find your SIM card number and connect the call and-- right before it connects, the call times out of rings and your caller is sent to Voicemail.
You never get a missed call alert, your caller isn't alerted that your phone didn't ring, and because your phone didn't get a confirmation, you probably won't get a voicemail notification.
This doesn't affect the phone's ability to connect to the 3G network or 4G LTE Bands 2 and 4, which lots of phones support. But calls and texts don't travel over those networks. You'll still have an active, working data connection if this is what's happening to you, which is why it's hard to diagnose not just for Ting reps, but our customers and other MVNOs, as well as T-Mobile itself.
This problem isn't going to go away, and it's only going to get worse as re-farming 2G goes nationwide. It's not Ting-specific. Any T-Mobile device will have this problem if there are enough 2G-talk-and-text users in your area.
The phone in question, the Blu Vivo 5, supports Band 2 and Band 4 for LTE, but doesn't support Band 12, and thus doesn't support VoLTE. This is exactly what's happening to you.
This is exactly how it happened to my S/O. She had a Motorola Droid Mini on Ting GSM that worked great for years, on two distinct T-Mobile-powered networks. Then, T-Mobile re-farmed enough 2G in our area that she started missing calls, texts wouldn't arrive and she wouldn't get voicemails. The key identifier that this was her problem was that placing a call would take something like 10-15 seconds to connect. Typically, this should be instant.
There was nothing wrong with the phone at all -- it was working as designed. The second I got her into a Band 12 VoLTE phone, the problems disappeared completely. Nothing else changed.
The only solution is a new (or new-to-you) phone that supports Band 12 and VoLTE. No number of hard resets, network resets or new SIM cards will fix this problem. You'll have this problem on any network that uses T-Mobile as their backbone, as long as the phone you're using doesn't support Band 12 LTE and VoLTE.

AT&T tech support said my OP7T not LTE Compatible

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...
AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal or data, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

I'll bet if you look in the settings your model is HD1905 or the global model, not sure the number.
Actually if you could take a look for me and post back here that'd be good. It most likely won't make a difference but I'm curious.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Anyway it's BS. If the carrier supports the phone, and the phone is capable of VOLT!/WIFI CALLING, it should work.

Yes Verizon. I have heard hear many times on this site, that phones are blocked from wifi calling by the IMEI, I or they could be wrong.
Vowifi works on the unlocked Pixel, but are they going to butt heads with Google? Volte works fine, I got a network extender, and I can use google voice to make calls over wifi if I really need to.
If vowifi is a must, get an approved phone, that is all you can do.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?
I was able to get it to make calls after a refresh signal was sent out, but it could not connect to mobile data . My sim is fine. I even popped it my son's Pixel 3a and LTE started immediately.
The seller is saying the fact that it was able to make calls means it is able to connect to mobile data. And I should take it to AT&T before returning it. I don't think he's scamming. He says he has the same phone on AT&T. And he's sold Hundreds of them. That kinda checks out based on reviews and some of those people do report it works with AT&T.
These phones are hd1907 T-Mobile but supposedly OnePlus unlocks them before sending them out to some sellers. I sort of believe the guy but is it true? If it were locked to T-Mobile could I get it to make phone calls?
Obviously I'm not talking about a hack. Because I thought locked was locked. Is it possible for a locked T-Mobile phone to make calls on the AT&T network?
Also I got AT&T to make it work but once I removed the sim/reinsert it, the thing displays weird behavior. Wifi goes in and out. It forgets the apn settings that were set prior.

I agree, ATT was the most horrible experience I ever had. Tracfone may have even had a better customer support.
Verizon CDMA service may be antiquated, but their customer service and tech support is 2nd to none.

It should have no trouble using data BUT you'll have to change the phone's APN settings to match your carrier before you can. You can google it and find them. It's not hard at all to change. Somewhere under the "network" settings.
Someone correct me if I'm wrong, but as I've understood it the phone will keep trying to access the previous carrier's data network, which is why you didn't have data. But as said above the APN settings should fix that.

If I told you the whole story, which started on Friday morning and in the end involved 7 AT&T employees, 6 on the phone and 1 in the store, it'd probably be removed because it's spam. Too long of a story.
But in the end it didn't get to connect to mobile data..at least not consistently. I took it to the store. The guy removed the Sim reset it, turned it off and boom! - LTE, calls and texts. His theory was it takes a little while for it to unlock and get set so when I tried it the other night it wasn't working.
I was happy because it literally took 5 minutes. I ran some errands and was out for like another 2 hours. Everything was working. Some point between the store and my driveway, the signal was gone. I never got it back. Of course I tried reset, remove Sim, reboot, change apn settings.
I called AT&T... the first woman didn't even know what CDMA and GSM was. I politely got her to transfer me to the guy who 'knows his stuff'. He got it to make calls again, but in the end concluded this device can't work on this network. I didn't wanna argue anymore. He had a BS answer for everything including 'If it doesn't work, why DID it work just a half hour ago?'
He said I could try getting a new sim. They have no idea. My son's sim won't work on this phone but pop it in my old phone and it works. And my sim works in his phone. It's not the sim. I know it.

I took it back to AT&T yesterday. There was someone in front of me so I sat down, removed the sim from my working phone, popped it in the op7t... instant lte, calls & texts. The same thing happened the day before I went to at&t. It worked perfectly well there in the store and even 2 towns away but not m my neighborhood which DOES connect to LTE, has for years on every phone we've had.
The tech (if you can really call him that) updated the sim. That got it done. I've had a working phone for 24 hours. BUT no LTE. It only connects to H+.
I haven't had time to call or go back to the store, but I'm hoping it's an easy fix. This has been the weirdest week I've ever had dealing with a phone. I've learned that AT&T doesn't know what they're doing. I still can't believe I needed to explain what GSM and CDMA was to one of the people on the call.
I'm gonna try a few things tonight after work.

Thanks for sharing, but I've never really needed to mess around with the settings as far as mobile data goes. It either works out of the box, or at most I'll need to put the apn in manually on some custom roms, but even that's rare.
How does the info you provided apply to my problem. I know the phone can connect to lte. It was connecting briefly on Monday afternoon and while I was at At&T yesterday, it connected before they updated the sim.
Is there something I can do with this? It's a sincere question. I'm not sure if I can apply it somehow. Thanks

I think his point was to show that the OP7T does in fact work on all AT&T bands. Normally you don't need to do anything with this if the SIM is provisioned correctly.
What are the chances that you are on the edge of the local AT&T LTE signal so it drops to H+ because that's a stronger connection? At the AT&T store the LTE signal is stronger so the phone is favoring that one. Some phones are more sensitive to signals than others (or more aggressive at switching to a stronger band).
Try using a program like "LTE Discovery" and see what bands you actually are connecting to. It can also let you know what is going on in your area with tower location.

I'll try that. Thanks.
That's what I said but the guy at the store said it's really not a stronger signal at the store. Plus I know I can get LTE at my house and in the store because all our other phones connect, even this one, briefly at the at&t store.
The seller have me a code to input into the dialer but I'm waiting for tomorrow to put it in. It's my day off. If something goes wrong it won't be a huge deal. I will look into what you sent at some point though.

Your posts are bouncing between VoLTE & VoWiFi.
LTE bands and VoLTE work fine on Verizon's network.
Verizon allows VoWiFi on the OP 8's that they sell. They will not activate VoWiFi on the OP 7 series, the claim is that the phone did not go through their security testing. IIRC VZW doesn't allow VoWiFi on any outside phone.
