[Q] verizon galaxy s3 on tmobile network help

Hi guys, so my mom has her gs3 on verizon and she bought a sim card for tmobile. We activated it and we get Edge data speed but nothing more. We live in a LTE area with great service but we just have edge. how do i get her data to LTE or HSPA+? Also when entering *#*#4696#*#* i dont get the option to change the LTE/CDMA radio like i use to

The vzw gs3 is not compatible with T-Mobile. Be glad you get edge
Different radios in the devices.

+1. Edge is all you can get with any non Verizon US carrier.

Fix for T-Mobile LTE?

Is there a workaround or any suggestions to get everything functional such as calls etc.
As of now only data works but you can't receive or send out messages,make calls etc.
When connected to H+ everything works flawlessly and the carrier shows, when connected to LTE only data works nothing else and the phone can't identify what carrier is being used.

UPDATE:
The issue seems to be that Verizon by default is locking the GSM radio. Users are reporting the same in the Moto X and Droid Ultra forum. Users using 4.4.2 on T-Mobile with a Verizon device.

I thought verizon was forced to sim unlock all their lte devices?

They are SIM unlocked as I'm using one but it seems the band we need for LTE isn't playing well.

Was curious if anyone else was having this issue. Any thoughts that it might be related to skipping Verizon activation? When I got the phone, wasn't activated and on first turn on it prompted activating Verizon Sim but I exited out and just popped in T-Mobile Sim.

AFAIK, LTE (unless the carrier is using voLTE) is a data only network. Verizon uses LTE for data and CDMA for calls and text.
Verizon seems to only allow GSM/UMTS or CDMA/LTE on the M8 at one time, there doesn't seem to be a true Global mode that allows GSM/UMTS and LTE to run at the same time.
That would explain why people are reporting either LTE or calls/texting (which, as above mentioned, only works on 2G/3G (be that CDMA or GSM))
The question is, is there a way to get around this? On the S3/S4 there was an app called phoneinfo which showed more modes than the Mobile Network settings menu. Is there such a thing for the M8?
This is quite disappointing news for me, since this is the first Verizon phone I'm aware of that has the 1800MHz LTE band, and that's the band used in Australia where I'm headed soon. I was excited about being able to finally use LTE there! I guess I'll have a choice between LTE and calls/text like all those in this thread using T-Mobile.

Hoping the best that this would be the fix for the GSM
while you edit the data as well I believe

Will never get 4G LTE on any other carrier besides Verizon in the US. Never have. Never will. Those radio bands are blocked at chip level.

More than likely it is same as Verizon. Won't happen till they have voice and data both over AWS network. Currently on Verizon data is on LTE and voice is on CDMA. If can get into signal settings may be a way to lock the voice section in. It is not on LTE. Verizon has had the two linked since TBolt. Others have had a problem doing this. Has to be able to do dual band at same time. Also shouldn't get LTE at all if not in T-Mobile AWS area.

Unless T-Mobile rolls out voLTE and the M8 is compatible, the VZW M8 won't work for both call/sms and LTE data simultaneously. The other solution would be figuring out a new mode that allows LTE and GSM/UMTS to work together, maybe a software update will do that, but something tells me VZW isn't running to make our lives easier in this regard (Unless they start offering international 4G LTE roaming, then they'll have to fix this issue - and that might be on the horizon as this is the first VZW phone to have LTE bands that VZW doesn't use nor has any plans to use, such band 3 1800MHz)

Verizon M8 on At&t/Cricket

I have rooted and s-off. Used the guide to enable additional bands. I used NV values 65626 and could get LTE in some areas but not in others. I'm starting to think it's radio related. Any suggestions?

what bands, specifically, did you enable?

Bands 2, 4, 5 and 17. I'm located in the Raleigh Durham area of NC. When it was connected to LTE I used the LTE discovery app and confirmed the uplink and downlink freqs. 1900/2100 if memory serves me correctly.

Currently using the VZW M8 on Cricket. I'm getting HSDPA but no LTE.
But I have no complaints. Phone is awesome and mobile data is working flawlessly.

Yes it's radio related. Verizon and ATT do not use all the same frequencies and bands.

Hi,
I tried to read any info about it. But I don't know....
Here is my theory: The Google Play edition (GPe) is open to any LTE channels. I know that you can turn the verizon M8 into GPe M8... (I don't know if the phone can operate on Verizon after all :S )
So hopefully that can work, but I NEVER TRIED IT!
So If some GURU can help us that would be grate. And also a "How to" -from the very beginning ( Stock rom, s-on, non rooted, etc) would be nice too.
Thank you
Ps.: I was only modifying Samsung, Sony, Motorola, Zte before. This HTC "magic" is totally new for me

I am in Virginia. Right now using a stock Verizon M8 and I do get AT&T LTE signal( download speed is around 10M, upload is 7M. Phone info said the network is LTE).
I guess my area using band 4 for AT&T LTE.
I am considering enable band 17. If you are available, maybe you should share some thoughts of your Band-unlockin process and your LTE signal situation.
Thank you.

I went to an ATT store inquiring about moving from VZW. They said my M8 would NOT work on their network. Who can i contact at ATT to get the straight scoop and move? I am in Wilmington NC.

Very competitive Verizon MVNOs are starting to emerge, have you compared coverage in your area? I'm on ROK Mobile and it's freaking awesome.

Most of the ATT guys are clueless, not matter they are in store or over the phone. Just ignore them.
All you need is get an att nano sim card, put it in your verizon m8. Boom! You could text and call now!
And then you need to edit APN settings to get data working. Go to settings, Mobile data, Network settings, GCM/UMTS Options, Access point names, and add a new APN:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
save this APN and select it to use. Wait 30 sec to 1 minutes, Boom, you would have H+ or 4G LTE depending your location. For most area you would get H+.
You don't even need to root !

im on edge slow slow slow

I get HSPA+ on my stock M8. My APN is "phone"

I have GoPhone account with AT&T and I get LTE in some areas, nothing done to my phone, stock Verizon m8, apn set to nxtgenphone , I get HSPA most of the time, but I do get LTE in some locations here

Using Verizon's S6 on Tmobile's network

Hi all, has anyone here tried or been successful in getting the data or lte over voice calls with Verizon's S6 using Tmobile? I have Tmobile and trying to use my gf's unlocked Verizon Galaxy S6. Almost everything works fine except that while on voice call, the signal drops to 1x and I can not simultaneously use data or receive mms. Are there any fixes for this? Any help would be appreciated as she is planning to switch from Verizon to Tmobile and I would love to just reuse the phone on Tmobile.
PS: Sorry not sure if this should be in a carrier specific thread. If so, not sure which one to choose since it sort of dual carrier concern

Verizon Model LTE Bands same as Unlocked Model?

Do you guys think the Verizon unit will have the same LTE bands as the Play Store model? I can get these st 2yr contract pricing on my Verizon business account and would like to use one on AT&T service, but need to be sure Band 12/17 is unlocked and ready for use.

The answer is yes, there are only different frequency bands for the intl and US versions. The US version, which Verizon is selling, supports all major carriers, according to Google.

My only concern is that the Verizon website does not list all US LTE bands such as Band 12 or Band 17. This was an issue with my Note 7 also. Band 12/17 were capable and supported by the hardware, but Verizon locked these from being used. It wasn't until I flashed AT&T Note 7 firmware onto my Verizon Note 7 unit that I was able to use those 2 LTE bands.

alright I take it back. According to google, it is carrier locked to verizon http://i.imgur.com/Jc9eV9E.png

This is 100% wrong. No Verizon phone's have been locked to the carrier for a few years now.

Correct they have been carrier unlocked since the iPhone 5 came out. Verizon still locks the LTE bands for data, however. The only phones that have unlocked LTE bands on Verizon are iPhones, because Verizon does not/cannot tamper with the firmware before boxing the phones up.

That is because Verizon uses the same bands as TMobile in many areas of the country, so those bands are unlocked. Verizon does not use AT&T's primary bands at all, so they lock it out. (Band 17)
As a quick example, AT&T uses Band 3 in more rural areas and I was able to catch a bar or two of LTE here and there on a 100% stock Verizon Note 7 with AT&T sim card in it since Verizon also uses Band 3, , but it would quickly fall back to HSPA because it lost band 3 signal. I verified this with LTE Discovery app. At my office I only have Band 17 from ATT, so I was only getting HSPA. As soon as I flashed AT&T Note 7 firmware onto the Verizon Note 7, I had full LTE signal on Band 17.
Since Verizon cannot legally carrier SIM lock their devices anymore, they still do what they can to make the phones as unusable as possible on other carriers with their firmware, including a message that pops up every time you start the phone saying "this sim is not from Verizon"
I'm trying to figure out if the Pixel will be the same story as my Note 7, in which Verizon locks out a majority of LTE bands. And if so, can the Play Store version firmware be flashed onto thr Verizon version of the Pixel to unlock these bands?
The Snapdragon 821 supports all LTE bands so I know it won't be hardware limited, only firmware limited.

The only reason LTE won't work on at&t is because at&t won't provision it unless it's an At&t branded phone. You can get around this by having them activte your sim in an at&t store phone. My brother used to have at&t and I gave him my old S7E from Verizon which had full LTE after doing that.

That is correct IF there isn't a LTE capable IMEI on your AT&T account, you would need to have them add the LTE capable IMEI and provision LTE. This issue is based on Verizon's firmware and their lockdown, however. I have thoroughly tested this and even entered service mode to see what bands are available with Verizon firmware vs AT&T firmware.

not good news for the verizon pixel with att. Some guy on the pixel xl xda reported he is getting only H+ with the verizon pixel xl. Definitely need more people to check it out. Donr believe PC mag one bit. They said bootloader was unlocked but it turned out to be LOCKED.

If you install LTE Discovery you can see the band you're connected do. If the phone can connect to band 12 or 17, I would say the Verizon version most likely supports all LTE bands.

I am using a Verizon Pixel currently on a 850Mhz/1.9Ghz GSM and Band 4 (2.1Ghz) and I am experiencing no issues. I used my carrier's SIM, and the only thing I had to do differently was update the SCMS in the *#*#3646#*#* to match my carrier's Service Center ID. This allowed my SMS to work. I experience no issues here as the phone operates as though it were unlocked.

I've even used the VZW pixel on T-Mobile and had band 12 carrier aggregation with band 2. Definitely not a problem and same bands.
I believe the only difference is the imei disallows bootloader unlocking. And the post boot Verizon three app install (which is an easy uninstall)
Doesn't att require the imei added for LTE? They audit accounts on the regular and if they find an unknown imei they disallow LTE.

Thanks for posting, VZW wouldn't lock certain frequencies (12 and 17) on the Pixels like others have stated since their phones have been fully unlocked for years. This phone works with all US carriers.

Yup and on top of that they seem 100% feature parity. I've even seen (on my Verizon sim) the option for volte video calling. And volte voice definitely works on T-Mobile as well as wifi calling.
Just the locked bootloader is the only downside.

The misinformation and confusion about this phone in general all the way around astounds me. It's actually rather simple. The only major difference in the Verizon variant from the play is that the bootloader is locked.
