Questions about moving to AT&T - Verizon HTC One (M9)

Hey everyone,
I was just gifted a Verizon M9 with s-off. It's currently running Lineage OS and TWRP. I don't have Verizon service myself, and I tried to throw my wife's AT&T nano sim in there (I have a micro sim and don't want to cut it unless I know it's going to work). For a few seconds I got fast H+ network access, before the data signal cut out. I've read online that the Verizon M9 should be GSM sim unlocked out of the box. I tried several APN's, but none of them brought back the data connection.
Am I missing a step? Is this not something that can be done? Is this an issue since she has a real AT&T sim, but it won't be an issue if I cut down my black wireless sim?

Well, my new Black Wireless sim came in and it worked just fine. Now I'm off to see if I can unlock some LTE bands.

Were you able to get AT&T LTE to work on the Verizon version? I was curious for a friend who might grab this phone and switch Straight Talk networks later.

I'm still working on that. I band unlocked the phone and my phone will connect to AT&T LTE for 1-5 minutes, then it loses all signal until I manually switch it to GSM again. I feel like the issue is at Black Wireless, but they don't want to add my IMEI to their database since it's a Verizon phone.

I also have a Verizon HTC One M9 and am using it on Cricket (which is owned and operated by AT&T). I'm able to keep a signal. H+ most of the time. If I manually reset the network, then do a network search then select Cricket, the signal will reset to 4G LTE for a few hours or until I get a call. After the call it gets stuck on H+.
I'm not rooted and s-off....yet.
Great phone though. If I didn't have Cricket I'd just settle for H+ all the time.
Hopefully this thread will pick up and we'll get some help staying locked into LTE

I did see a thread around here with a tutorial on how to edit the bands in the phone and even add more bands. But you have to be rooted.
I'm going to try it when I get the spare $25 for the Sunshine app.

From my experience tearing down my VZW M9, I think that the VZW version has a completely different antenna. When I replaced my USB port, I noticed the VZW version only has one antenna connector going to the USB connector, where the GSM versions you see in tear down videos have two.

There was a thread where someone mentioned to edit some folders in setup, I think, and relabel Verizon to whatever GSM you're switching to.
But I can't find it.

Use Verizon Note 4 on AT&T?

As Verizon is charging $700 compared to the 800+ at&t is charging for an off contract note 4 I was wondering if its possible to use the off contract verizon Note 4 on AT&T. I have a mobile share plan with AT&T with other lines still in contract so I can't easily switch to verizon or I would. Does anyone know?

How would one use a CDMA device on a GSM network??
It was my understanding that all Verizon phones now had a SIM slot for LTE Compatibility? I assumed if the Sim slot was unlocked you'd be able to put an AT&T sim card in and configure carrier settings and get access but wanted to confirm?

Most modern Verizon phones have GSM radios in it, and it's unlocked.
The problem with using Verizon's Note 4 on AT&T is LTE. They don't have the same radio, so you'd be stuck on AT&T's 3G.
This was the conversation I had with an AT&T rep today. She was convinced I could just buy the Note 4 from VZW at $699 and bring it over to AT&T... she didn't mention, nor did she seem to be aware that LTE would not work.
Yes well, it all depends on the ATT LTE Band that's in use in your area. I have a VZW S5 that's on ATT prepaid pulling LTE all day. Band 7 I believe.

VZW phones generally have radios with some overlapping LTE band coverage with both ATT and TMO. AWS Band 4 I believe is used by all 3 carriers but not in all areas of the US.
Unfortunately VZW mainly uses Band 13 and ATT band 17 although supposedly Samsung devices have this enabled in the Hidden Menus but I have never gotten band 17 on ATT.
My 2 cents
Verizon's website says their model supports bands 4 and 13. The AT&T website says their model supports bands 1, 2, 3, 4, 5, 7, 12, 17, 20, and 29. From what I remember, AT&T's primary LTE bands are 4 and 17 so if Verizon is being completely truthful and it doesn't support any other bands other than 4 and 13, your LTE coverage may be spotty or even completely non existent.
Verizon Note 4 is out now...
Anyone have a report yet?
I can confirm verizon note 4 is working on at&t & tmobile.
I just got my verizon note 4 today and i put my tmobile sim in it and i had to do apn settings and it worked fine the only problem is lte is not working it worked on hspa and my speeds were 6mb down and 2.5 mb up. Which is good for me.
But if u want to use lte u have to enable band 4 which is locked on verizon model. To enanble it u neef to root ur phone with chainfire root (it's the only method to root right now) but it will trip knox sensor and void ur warranty .
And same applies for at&t. No lte but 6mb on hsps looks good to me.

Im using it right now on AT&T. Im getting HSPA+ but no LTE. For some reason I'm having trouble sending MMS though. Anyone know of any tweak I could make to the APN to get MMS working?

U just need to enter the right apn settings. I'm getting mms just fine on straight talk. My problem is that our phones support air view with pen and finger, and yet they buried the setting so deep we need root to access it and make it stick. I used nova launcher to access the setting but it turns back off once the phone is put to sleep. Stupid! Just let us decide If we want it or not!!!

Finally have the APN set right to send/receive mms. Problem is anything over 1mb fails. Pics send and receive just fine but if for some reason the pic is say, 1048kb, the mms fails, everytime.

Got Messenger from the Play store, (the Google one) and had the same issue. So I closed it out and re-sent via Samsung messages and lo and behold it went through. I'm far from noob but not quite understanding the picky nature of sending the mms!

At least you got it to work finally. :good:
Just ported my work number (verizon) to my personal account (ATT) and they let me keep my note 4. I used the APN settings for the ATT S5 and am getting around 10mbps/down and 2-5mbps/up. I'm not rooted yet but will be working on that to see if I can get LTE functional.
I use Hangouts for SMS so that was already working.
s5 settings I used...

I have a POS s3 mini as a work phone (att) I've put that Sim in my Verizon s4 and all was good. Traveling internationally put the att Sim in my vzw note 4 I get voice but not data connections.

So the Note 4 requires root to enable the service menus in order to enable the various bands available on the phone. Verizon has chosen to restrict this access. You need to modify the build.prop and the efs\carrier\hiddenMenu file. So until a root procedure is available the retail version is stuck with HSPA+, which isn't too bad I guess.
Working on my s5 I have made the changes but I am still figuring out how to exactly turn on the disabled bands. I am also hoping these modifications will apply to the Note 4 once root is available.

You have to modify the APN settings after you put the ATT sim in the VZW phone.

I'm wondering if anyone has tried flashing the phone with ATT's firmware. Perhaps this is a more benign method which, as a plus, would show ATT logos throughout the interface. I'm having a verizon note 4 given to me; I'm considering my options.

4G LTE & signal bars disappear about 30 seconds after powering on. What's wrong?

So I bought a Verizon Note 4 (Verizon sim from previous owner installed) and a Gear S from a person off craigslist for $400 total. I have not activated Verizon service yet, only using on WiFi for right now. The phone has been updated to the latest BOG5 firmware from Verizon, so looks like no root for me as well ... Anyways...
...Is it normal for the phone to show 4G and a signal for about 30 seconds after powering on, then have no signal or LTE? Again, I have not activated the phone on Verizon yet, so keep that in mind.
I have checked the APN, and it seems I can't change or edit the Verizon APN. It is greyed out. It also seems it's incorrect. I'm wondering if this is why I get no signal at all.
Anybody have any ideas? I tried putting my metro PCS sim in it as well, and same result, no signal or LTE icon. Even added the correct APN for metro PCS and still nothing.
I also have a Verizon Samsung S6 Edge Plus that is not activated yet either, with a Verizon sim installed and it shows 4G and signal. Also, I can put my metro PCS in the Edge Plus and it works perfectly, without changing or doing anything.
Anyone have any idea as to why the Note 4 isn't working?

Will this phone work on Verizon

Hi guys,
I am looking into getting this device. However I am not sure if I can use it with verizon. I had a little chat today with a verizon rep after shipping my note 7 back and I got told that I could now use any phone with verizon as long as it has a sim-card slot and one of the regular sim sizes (microSIM and nanoSIM).
Anyone tried it with verizon?
I belive its gsm networks

According to Verizon I can use any unlocked phone which accepts a SIM card....
Its a lot of money to be stuck with as paper weight
I also would like to know this.
Voice and SMS Only so far for me.
No LTE as VZW requires Band 13 for BYOD phones and this phone does not have 13.
It does have EV-DO so 3g should work but I can't get it to.
Ah to bad. Such an amazing phone. Just crazy that the world can't unite and standardize frequency bands and protocols. We were able to have shipping containers and the cigarette lighter plugs standardized . Too bad that we can't do it here.

can i flash USCC N5 with AT&T N5 firmware

hey guys/gals i have a USCellular Note 5 which is unlocked and recently switched to AT&T and everything works but MMS and 4G is flakey, usually bouncing between 4G and H and H+ (on the signal)
i dont feel data speeds suffer but speed tests show it is compared to my LG V20, so fear signal reception could be different that an AT&T note 5.
anyways, does anyone know if it is possible to odin flash tan AT&T rom into my USCellular phone and make it run properly on AT&T.
the NOTE 5 is of course unlocked and when looking at the specs is only missing 2 cellular bands and has more bands in 3G than the AT&T variant.
anyone have a clue, i would not like to brick this phone beyond repair because i can still sell it for someone wanting a USCC variant, but am willing to flash it with an AT&T rom if that will fix the MMS issue.
the APN's are correct, but i did install KIK messaging and when setting MMS to manual APN it immediately came up with a uscellular APN which really makes me believe somewhere in the phone its still holding a USCellular APN and not using the AT&T one even though it is set in the Network settings of the phone.
the phone did download the small october security update, but it still isnt sending mms messages.
No, the branding will stop and fail Odin.

Also if the APN is force switching. It means the AT&T APN settings are wrong.
I found it!!
The APN proxy was misspelled.
I don't know if the guy in the store did it or if it pulling from at&t but everything was right but the proxy was .ent instead of .net
I never changed it cuz I always looked at it and said yup that's right
Last night I noticed it and now it works
Just gotta keep an eye on the 4G stuff now

Question for folks that's been on the oneui 2 beta. Does/did data roaming work?

I remember there was an issue with data roaming during a beta for oneui 1.0 beta last year... but i've not seen any complaints this time. Just wanna be sure if everything is good... otherwise i'll bring a backup phone on my trip this weekend... or flash back to pie. haven't decided yet.
Bummer that it doesn't seem like US will get stable 10 before my trip... but alas.
To add a question to this thread, is there a difference between unlocked versions and carrier versions with data roaming? I'm on T-Mobile and I've heard that data roaming only works with the carrier version, but have not been able to confirm this with any certainty.
ROAMING is just that. Should work regardless of where you are as long as your carrier has deals worked out with the carriers you are trying to roam with. I'm on Google/FI, all I do is ROAM since its a VMNO. I'm on a U1 unlocked, with beta 3 One UI 2.0 and no current issues with connection or roaming.
---------- Post added at 12:16 AM ---------- Previous post was at 12:10 AM ----------
no, there is NO difference between carrier roaming with branded or unbranded versions. Official phone or not. If the DEVICE has the bands you are trying to connect to, (automatically) and your carrier supports the network Operator you are trying to roam on. It will work. The handshake is something like this.
"Hey ORANGE! I'm a T-Mobile Sim card from USA."
" Hey! Wait a sec, let me check something. Yeah You're good. Enjoy my towers." <- Even If it is TMobile Canada, or Mexico, etc.
Then TMobile will send you a ton of texts Welcoming you and saying International data rates apply, texts, talk, etc.
