LG G4 VS986 on T-Mobile LTE problem - Verizon LG G4

Issue:
Phone will not stay locked on LTE in Global or LTE/UMTS/GSM mode. When in Global or LTE/UMTS/GSM mode and LTE does connect, it's momentarily and when trying to run a speed test or open a webpage, it quickly disconnects and connects to HSDPA. If switched to LTE/CDMA signal locks in great and data speeds are great however voice services are not available. Any thoughts or advice is welcomed. Thanks ahead of time!
Facts:
Phone: VS986
Android Version: 5.1
Build: LMY47D

What band LTE are you connecting to? I found that here on band 2, I will connect at first, but then it switches back to edge. Seems fine in a band 4 LTE area though.

I'm in the Raleigh NC area. According to LTE Discovery i'm using Band 4. and I also experience the same. A brief connection while in global or LTE/UMTS/GSM mode then it falls back to HSPA.

I haven't found LTE Discovery to report the band correctly, at least in my case. It would say I'm on band 4 on my Moto X, but when using a band 4 only device I would only get Edge, but when I go in a confirmed band 4 area it works fine. From what I've found, most 2G > LTE sites were converted to band 2 LTE. Although since you get HSPA the chances of it actually being on band 4 are higher.

I'm fairly certain this is a Band 4 area. The latest T-Mobile maps are pretty good about pointing out Band 2 areas. I've since sold the phone and acquired a iPhone 6 Plus which I'm looking to sell to replace it with an international G4 or T-Mobile G4. I was pretty impressed with that phone. If I had to rank my favorites, it's number 2. Nexus 5 is still king of the hill for me. There wasn't a better phone out when it was release for a better price.

did you ever figure this out? samething is happening to me

Unfortunately I didn't. I sold it and bought one for T-Mobile...... Which I just sold about 3 hours ago.

So I tested it out again, and in a band 2 area when I boot up my phone with a T-Mobile SIM, I get LTE for several seconds then it cuts back over to 2G.
Now that there is a new software update for the G4, I wonder if this is anymore reliable. Anyone who took the OTA update in the past few days, can you let us know if it's any better?

Been there, done that...wanted to switch over to T-Mobile, but unfortunately, the VS986 only works with two of their three LTE bands, as you know, and it seems everywhere I went, they were using the one the phone doesn't receive (I'm in southern California, for what it's worth, but tested it on a freeway run up the I-5 to the central part of the state - only got 4G-LTE in a few places). Wound up going back to Verizon

I'm getting the exact same results in Burlington, VT (T-Mobile band 2 market). I first have to manually select T-Mobile (defaults to roaming on AT&T HSPA+) then LTE works for less than a minute (LTE Discovery says band 4) and then I lose signal when I get signal again, I only have edge. It does this constantly and is really annoying.

Aww, bummer. I was thinking about switching to T-Mobile, but looks like that is not a viable option? So no one has been able to successfully use the phone on T-Mobile, even after enabling bands 2 and 4 only?
This whole plethora of LTE bands, where each provider does its own crap is such a mess, is just serves to lock in customers, since switching phones is expensive. Government should mandate that all phones can work on all US LTE bands, the technology exists.

I am on the same boat. Everything works on my VS986 on t-mobile network. but I cannot get the LTE to work properly. LTE discovery shows band 4 (not sure if correct though)

My VRZ LG G4 shows that it has Band 2, 4, 5, and 13. I tried enabling 2 & 4 only, 4 only, 2 only, 2&4&13 only but with no success.
What is interesting is I am coming from VRZ LG G3 and LTE was just fine and never had an issue.
I looked at the VRZ LG G3 LTE bands and I see Band 3,4, and 13 enabled. It did not even have band 2.

More testing:
When I switched the Network Mode to LTE/CDMA I get constant 4G-LTE & internet is working but my phone cannot place and receive phone calls.
with LTE/CDMA I see 4G at 100dBm and 1X at 120dBm

Interesting, almost sounds like a bug in the LTE/GSM mode.
I assume when you switch to global mode, voice works but only HSPA, right?

I think since someone reported before that this used to work the G3, it sounds like a bug to me. I guess we can hope and pray that this will work in future releases, but there is no guarantee of course. Not sure what complaining to Verizon will do, since they are probably not very interested in you using T-Mobile. Of course, you can always wrap the complaint into something like you are using the phone in a different country on vacation and it doesn't work. Maybe a complaint to the FTC could work too, since it sounds like Verizon is required to have their phones unlocked for use on other networks based on some settlement.

I am tempted to try the guide in here to add more LTE bands:

While some testers said the LTE bands are limited by hardware others reported some success modifying the software. Any thoughts?

[Q] T-Mobile SM-P607T - cannot connect to 2G/Edge network?

Hello gang,
I picked up a new T-Mobile Note 10.1 2014 edition 2 days ago. So far, everything seems to be great. There is one issue however that seems perplexing. My tablet connects to 4G and LTE networks just fine but for some reason, it will not connect to 2G/Edge networks near my home. I live in a rural part of PA where T-Mobile doesn't have 4G/LTE coverage. My Samsung Galaxy S3 connects to the Edge network near my house without issue. However, my tablet does not connect and simply shows a small X where the signal meter is.
I spoke to T-Mobile tech support this morning and they seem to think that the band covering 2G may be dead. Could this be possible when 4G and LTE work just fine?
Also, the options under Network mode are now limited to 2: LTE/WCDMA (auto connect) and WCDMA only. My SGS3 has a GSM only option which the tablet seems to be missing.
I am running Android 4.4.2. Any thoughts / suggestions?
Thanks!

I can't state this as a fact for the tmo P607T but remember that the tmo 3g version of the
Samsung galaxy tab plus 7.0 had a similar situation. Users were looking to add phone functions
to this device.
Turned out on the xda threads that the tmo tab plus 7.0 had no hardware
to support phone functions as the international version did.

The GSM mode only makes it so you can force the Device into 2g or Edge mode. If you do not want to use LTE just pick WCDMA which is 3g/HSPA+ and GSM(2g/edge). If you are looking to turn off the T-Mobile data part Pull the Sim card out or just put the Tablet into Airplane mode which you can till turn on Wifi. I bought my Note just for Wifi, and using EIP. So i am not using it with T-Mobile Data. getting a data plan on the tablet is a big waste when you can just hotpsot your phone.

Well, it turns out that my tablet is defective. T-Mobile is sending me a replacement. I spoke to several tier 2 techs including one Samsung specialist and they all concurred that the band governing 2g on my Note must be inoperative. Weird right?
Well I got my replacement Note in the mail yesterday and it also will not connect to the 2G/Edge network near my house. I highly doubt I could have gotten 2 bad tablets in a row so there's something else amiss here. Perhaps the specs on T-Mo's website is incorrect and this new device simply doesn't have the capability to go to 2G/Edge or the modem firmware being used is a crippled version.
Very disappointed to say the least; yes Edge is horrendously slow but can be beneficial in a pinch sometimes. Any thoughts?

Yeah, I think you're right; despite unlocking mine and using it on AT&T (which does have better coverage), there's places on my commute where there's 4 bars, yet no data transfer. I've yet to see an "E" or "3G" symbol, either.
I'm thinking about trying to flash the P605M radio, but that'll have to wait 'till the weekend.

Please keep me posted on your results if you do end up flashing the modem. I'd be very interested to see what you discover.
I wonder if this move by T-Mo to cut 2g/Edge compatibility has something to do with their rumored intention of converting all of their 2g spectrum to 4g? Even if that were true though, that precludes using this as an unlocked device in other areas or countries that may only have 2g/3g coverage. What about data roaming?

Well, turns out that I might put that off a little bit later than the weekend- I've since had mine unlocked and as it gets the VZW LTE bands, I'm going to see how well it does on that (VZW drops back to CDMA in non-LTE areas, so I'd be completely without service). VZW LTE is pretty ubiquitous from what I'd seen with my OG Xoom, but if it turns out I lose service on the train in large spots I'll revisit GSM options again.
Besides, I might just flash the radios just to see what happens

Switched to Straight Talk, using TMO SIM, only get EDGE, can I get better data?

Hey guys, I asked awhile back about switching to ST and I've done it. I finally got data working by using a TMO SIM, but I can only get EDGE, no more, no less. Even in relatively large cities in my area that have TMO towers, I only get EDGE. My question is, is there anything I can do to get better data?
I have Verizon LG G4 on Straight Talk Verizon Towers and everything works great! Not sure what your issue is. Only issue I see is when I make a phone call, it drops to 1x always

That's because you're not using Advanced Calling (VoLTE). On Verizon's network, calls always drop to 1X unless you're using Advanced Calling. In the past, most Verizon phones didn't indicate this. They would continue to show whatever data connection the phone had (3G, 4G) even though the call was being done over 1X. Several recent Verizon devices have been more honest about which networks are actually in use, including the G4.
So, what you're experiencing isn't an issue. It's what should be happening.

That's because you're using a Verizon ST SIM, the OP is using a T-Mobile ST SIM. Also, you need to enable Advanced Calling on your account and your phone to use voice and data at the same time over LTE.
To the OP, I have the same problem. When I put my T-Mobile SIM in my VS986 I only get 2G at home, while LTE only works in the older LTE sites that are using band 4 primarily. Most 2G > LTE sites are using band 2, which according to the Verizon spec page this phone supports, but it must not be active as it doesn't work. I've been looking at ways to enable band 2 without any success yet.
To the OP, you added the APN configs for Straight Talk T-Mobile, correct?

I just opened a thread asking about VS986 wcdma bands availability. I was reading LG specs and they say this phone has no 3g, just 2g and LTE. Reading in many other web pages they say this phone has all 4 wcdma bands available. Maybe they are software locked?
I think, I made a mistake buying this phone to be used in a GSM network. Have you checked with Verizon/Tmo rep?

What are your LTE speeds like? I thought about making the switch but then I read that Verizon limits LTE speeds on ST to 5MBPS...Is that true? As it is my 3g+ speeds end up being faster than that most of the time.

Turbo 2 Works on TMobile

Well, since the Force is out and the DT2 seems to completely lack dev support and rooting method, I am very seriously considering dumping VZW for TMo. Picked up a prepaid sim from 7-11 to test out tonight.
I live just over the river from NYC in NJ and commute to Bryant Park area daily for work. Will be periodically posting my impressions here. Plan on swapping SIMs for a few day to put TMo thru the ringer before pulling the trigger on an X-Force
So far working completely, both Voice & LTE. Not sure if I am getting VoLTE or true GSM Voice service, as I do not know of a way to test. I have been sitting comfortably on Band 4 for LTE when outside with 4 full bars of service. Inside my apartment, 4g is spotty with TMo (I live in a garden level place, half underground half above in a brownstone), however without band 12 present in the phone, I dont expect blazing or strong 4g signal indoors.
I do however get strong HSPA+ inside which has been pretty fast through basic web browsing and small app downloads.
What has blown me away is the speed of the TMo network, both HSPA and LTE. I took the following speedtests (same spot, swapping sims & letting connection settle). While it is harder to get 4G LTE inside with TMo and no band 12, when I do get it, the speed still BLOWS away VZW
Pic 1 - Verizon Indoor (foyer) - 4G LTE
Pic 2 - T-Mo Indoor (foyer) - HSPA +
Pic 3 - Verizon Outside - 4G LTE
Pic 4 - T-Mo Outside - 4G LTE
Pic 5 - T-Mo Inside front foyer - 4G LTE (verizon speed was same as previous outside pic)
Pic 6 - Verizon Inside on Couch (middle of apt) - 4G LTE
Pic 7 - TMo Inside on Couch (middle of apt) - 4G LTE

It'll work on GSM carriers (T-Mobile, AT&T, US Cellular, etc.) but not Sprint since it's a CDMA network. Phones with CDMA radios are allowed onto a CDMA network via a code, and Sprint blocks codes from Verizon phones, and vice versa.

how did you get the turbo 2 to work on tmobile?
im in nyc and have turbo 2 on vzw and had an extra one as backup. a buddy in tampa florida using a galaxy s6 regular on tmo kept having issues with his fone. i sent him my backup which is exactly the same im using. he put his sim into the turbo without any problems and works fine. he gets no dropped calls for whatever reason. he thought he would miss his wifi calling but since the fone is better at reception all around he doesnt need the wifi calling and of course he has unlimited data using his Tmo sim and its on LTE . only thing he said he has missed is the turbo 2 doesnt have infrared for his samsuck tv and other controls he could have used via his galaxys infrared. hope this helps.

All Verizon LTE phones are network unlocked by order of the FCC ever since 2011, 2012. It was an "agreement" Verizon was forced to sign to get more LTE spectrum.

It's old news. As long as a Verizon phone has the necessary LTE bands, it will work on any other LTE carrier.
Droid Turbo 2 has LTE bands 2,3,4,7,13. T-Mobile uses LTE bands 2,4,12. So, he's getting LTE bands 2,4.

I'm assuming this means I could use my droid turbo 2 outside of the US and just swap in a local sim (and use LTE if those countries use 2,3,7 or 13)?

Yes. For countries without those bands you would rely upon HSPA or even GSM.

What LTE bands does your carrier use? Info i found says 1, 3, 7, 8, 28. Droid Turbo 2 had two of those (3, 7), plus HSPA of course.

LTE on T-Mobile not working AT&T working

So I got my pixel xl from Google today. It works but I am on T-Mobile and it will not connect to LTE band 4 or 12 which are in my area. I have an ATT SIM for my work which I popped in and it works fine. That said without driving around Atlanta to try to find B2 I cannot tell if it is T-Mobile or the phone. Is anyone else on T-Mobile getting LTE connection at all?
So news today I can connect to LTE. Yesterday when I got the SIM in using *#*#4636#*#* I would get zero reception forcing LTE only. The phone would only connect to UMTS/HSPAP. Today after several restarts and calling T-Mobile and Google support it is now working. Here is what I did.
First Google is saying the update is supposed to affect LTE connecting issues.
Second make sure your SIM is properly registered with your provider. They should elevate the issue to higher tech support to have them look into it. This takes up to 24 hours.
Third go to your dialer do the *#*4636#*#*, go to phone info and change the preferred network type to LTE/UMTS or LTE/WCDMA (I haven't seen a difference between them). (This info is in other threads) Then restart your phone.
The problem seems to be how the phone determines what bands the network provider uses. It defaults to CDMA as the voice connection. For me this meant the phone was always connecting to UMTS only. It seems the firmware has some kind of default setting when it senses an error out the gate. The APN settings and preferred network settings needed to be updated and the phone restarted for it all to work. I now connect to band 4 LTE in my area. I hope this helps others.
I am also getting slow data speeds on my pixel XL connected to t mobile
My XL seems to get pretty consistent LTE service and good speed on T-Mobile.

Weird. I'm getting pretty awesome Band 4 coverage in So. Cal. I also get Band 12 here, but Band 4 is what my phone tends to be connected to, which is fine since it tends to be significantly faster.
I'm in Oklahoma on t mobile getting slow connection compared to my friends. They each have a galaxy s6 edge and get between 70-80 MBs down sitting right next to me. I'm getting 14 MBs down. I just left sprint today for slow connection. Hoping to find a way to get this resolved ASAP.

I only experience the issue in downtown Toronto area and I contacted my carrier, Telus, in Canada. They confirmed that network signal in such area is mainly LTE band 4...
Just an FYI for those with the same issue. Google has asked for my shipping address after contacting them about the issue.

Have you tried swapping SIM cards?
I pulled the sim out of another working TMO iPhone6s and my PIXEL got LTE right away.
Have an update and updated the main post.

Thanks. I changed mine to LTE/WCDMA. Will know how it goes next week.
All seems to be working on my end.
I was having delays in mms being sent. I was using the default APN. About a week ago I changed the APN to the one recommended by T-Mobile. Mms sends instantly now just about. I don't think it's effected much on LTE but I didn't have problems before. Make sure your on the proper APN
I sure hope there isnt a recall..My XL hasnt even shipped yet and im on Tmo
I spoke with a t-mobile rep yesterday who helped me get my issue resolved. My main apn was set up incorrectly. Now I am connected to LTE and not just hspa+. I get generally good speeds most everywhere and I have tower right by my house that must go fairly unused.

Question Cannot Connect to 3G/WCDMA

My 6 Pro (unlocked, rooted, January update) is unable to connect to my carrier's 3G network. My carrier is Xfinity Mobile (uses Verizon's network) and selecting 3G in settings or dialing *#*#4636#*#* and choosing WCDMA only, GSM/WCDMA preferred, etc results in my mobile connection being dropped. I can make and receive calls/texts just fine, and no problems connecting to their LTE or 5G networks. I am using the physical SIM from my old Pixel 3 XL, which had no problems connecting to their 3G network. Are there any fellow Pixel 6 Pro owners out there using Xfinity Mobile or Verizon as their carrier, and if so can you connect to 3G?
I just can tell you what happened in Germany, Operators disabled 3g networks. Maybe the same happens for you now
Aren't they in the process of killing off 3G, especially cdma? Very old tech.
I sure hope that's not what's happening, at least not until LTE coverage is on the same level as 3G. It just seems odd that 3G would be working fine one moment on my 3 XL (I only used 3G on it), then suddenly quit a few minutes later after transferring my SIM to my 6 Pro and getting it set up.

Where are you where LTE coverage isn't good? LTE is starting to be replaced by 5G and LTE is at least 7 or 8 years old by now. Do you live in a rural area?
The 3G Network Shutdown May Disable Your Phone (and More)
Mobile carriers are shutting down their 3G wireless networks to make room for new technology, but this change can have a big impact for anyone on older devices. Starting in 2022, companies like Verizon, AT&T and T-Mobile will phase out the older wireless network to accommodate expansion of 5G...

3G CDMA Network Shut off date set for December 31, 2022
We will turn off the last of the 3G CDMA network on December 31, 2022. Customers who still have a 3G device will continue to be strongly encouraged to make a change now.

I found both of those articles. And according to the second, Verizon is shutting down it's cdma network effective December 31, 2022.

At home coverage is fine, but when I head up into the mountains to snowboard like last weekend, then I'm screwed.

Darn, I guess I'd better start bringing change for the pay phone when we go skiing/snowboarding...
I'm surprised there's any coverage at all in those places. 2g should work which is emergency services.

The small ski resorts on the east coast that I go to aren't too far from civilization. My 3 XL had no problems picking up 3G at these places.
Do you know if those towers are still doing 3g or they switched them to another frequency? I haven't been on 3g except when traveling in Europe.
Xfinity Mobile's 3G is not GSM/WCDMA but CDMA/EvDo because they're using the Verizon network. That's probably why it's not working. Try using that setting.

I still need to contact my carrier and ask if/where they've started disabling 3G. I would not be shocked if they've started shutting it down near my house, but I would be surprised if the towers near the ski resorts were not still doing 3G. Driving through the small rural towns on the way to the resort is like going back in time 50-100 years. These areas seem like they're last on the list to get any form of infrastructure updates.

Still no luck. I suspect Verizon has started disabling their 3G network in my area, or uses a frequency not supported by this device.

Yeah it should definitely be supported by the modem from the specs I've seen but it's probably being activated as CDMAless now that I think about it because there was an issue early on where chat functions didn't work right unless it was activated that way. There was a whole big uproar on reddit about it with the 5a and then it happened again with the 6/6 Pro.
