[Q] Whether does I535 support Tmobile or ATT WCMDA - Verizon Samsung Galaxy S III

I just bought a I535, unlokced and rooted. But seems it can't support either ATT or Tmobile WCDMA. Ive set up a correct APN, but it can only work under Edge network.(no signal if I change to WCDMA only) Is there anyone who use Tmobile or ATT? How can I do? ROM 4.1.1 VRBLK3

Hey lil buddy, i have probably 6 galaxy s3's one being my i535, and its my most pristine condition Gs3, i use a i747 which is an ATT GS3 as my main phone, all are unlocked, now from what i know about the i535 and i hope im wrong, is since its a CDMA phone, it doesnt support the same bands tmobile and att use for 3g/4g/LTE data, my i747 is on straight talk and works awesome, 2 of my tmobile T999's work awesome aswell, but only get HSPA+, which is 4g, but from what i hear on our i535's we cant get anything above EDGE when running on Tmobile or ATT.....i hope you find a solution cuz if you do please tell me!

[Q] Rodgers to Wind

This may seem a dumb question but here it goes anyways. I have a Samsung Galaxy Nexus S that was on Rodgers with the following info:
V. 4.1.2 ......i9020AUCKF1......Build JZ054K. When i insert my Mobilicity sim card, it doesnt connect to their network. The sim works fine on other phone. Is there a way to flash or change some setting on the phone to make it connect. Thanks very kindly.

Rogers Nexus S does not support Wind/Mobi frequency (1700 AWS on HSPA). Model i9020A is what rogers carries whereas i9020T is the model compatible with Wind/Mobilicity.
p.s. it's spelled Rogers not Rodgers; no idea how someone mispels that when the brand is basically everywhere in Canada.
Cheers.
They are different frequencies and won't support eachother.
Rogers phone's won't work with Mobilicity/Wind sims, and wind/mobilicity sim cards will only work on rogers' 2g network (no data).
This applies even if the phones are unlocked. Only way a rogers phone can work on mobilicity is if it's a penta band factory unlocked phone, but the Nexus S isn't. Some Galaxy Nexus are but you have to confirm before buying.
You should now resell the phone and buy one that's originally from Wind/Mobilicity and make sure it's unlocked. Then it will work.

[Q] How do you improve speeds on Unlocked Verizon Samsung Galaxy S3 SHC I535

So I recently made my Samsung Galaxy s3 SCH I535 (originally a Verizon carrier) into gsm mode which now I have my AT&T SIM card in it.
Everything is working fine but the data. Rather then being on 4G LTE which is what I am paying for.
Is working on edge speeds. Can someone help me fix this?

Well, the Verizon version only works with Verizon's LTE. If you want at&t LTE to work, you need an at&t phone.

On the hardware side, Verizon phones only support Verizon LTE. So like the above post said, you'd need an AT&T phone to get AT&T LTE

[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.

How to Convert Verizon M8 to AT&T

Hello,
I have a Verizon M8 that i'm using with AT&T. Is there a way to convert my Verizon M8 to AT&T so that I can get LTE? Or can I at least flash the AT&T radio? I noticed this video shows a method for converting Verizon M8 to Tmobile https://www.youtube.com/watch?v=6GhybCyd4Pg He is getting Tmobile LTE with Verizon M8 no problem.
If someone can point me in the right direction that would be great!
This phone doesn't have the bands for At&t LTE. Best you would get is HSPA+.

Yes I know it doesn't have compatible bands for AT&T LTE. It doesn't have compatible bands for Tmobile LTE either, but someone demonstrated how to convert it so now he's using the Verizon M8 and is able to get Tmobile LTE without a problem. So there seems to be a way.
I figured it out. For anyone else out there that has a Verizon M8 and are using it on AT&T, you can convert your phone to the AT&T variant. I'm getting LTE but not constantly, it switches between LTE and HSDPA but it's staying mostly on LTE. Yay!

So how did you get it to work ? On the verizon forum all there is, is for converting to tmobile lte and nothing on converting to get at&t lte. Also what lte bands of at&t are you running on ?

Hey there. I posted how I did it somewhere in the AT&T forum. I'm not sure where the post is though as it's been a few months and I don't have the M8 anymore. I sold it and bought a One Plus One, then sold that and bought a Note 4, so that was a couple of phones ago.

[Q] Galaxy S6 Verizon on AT&T

Bought a Verizon S6 to use on AT&T.
I setup AT&T's APN settings on the S6 and I have accessed H+ but not 4G LTE.
Can anyone offer any insight?
Most Verizon phones do not get att lte. However I do know the Verizon Droid Turbo, 2nd Gen. Moto CA and Vzw iphone 5s and up gets Att LTE.. .
AT&T SIM on VZW S6
Hello,
I have the same question how AT&T SIM would behave on VZW S6.
1. Which APN Are you using? Are you using phone or pta APN?
2. When receiving incoming calls, does the format look like example: +8085551212 missing 1?
your response is appreciated!!!

I got 4g lte .. I used both settings and when I make calls out it drops to 1x and then when receive calls I have 3G. Seems like the pta settings works better didn't see and h or h+ which. Did on the phone apn settings. I have a Vzw iPhone since I work there thought the s6 would be easy since know the turbo works. There's something missing and can't find it. Everything works I do get the +then the number tho. But haven't had issues sending or receiving texts. Just it should drop to 4g when on the phone and should work whether I get or receive calls. Minor issues happening I did switch it to gsm instead of world that may have been why h or h+ didn't occur with pta. I'll update what I figure out if you all do so as well
i remember seeing it somewhere, but can't find it when i need it, how do i permanently disable the non-verizon sim warning when using any other sim in the vzw gs6?
(i have succeeded on a one time basis by force stopping activation agent, but there's a permanent fix if i'm not mistaken)
Verizon variant doesn't support AT&T's original LTE layer which is Band 17. So you won't see LTE on your Verizon variant unless AT&T has either Band 2 or Band 4 deployed in your market.
At&t LTE worked just fine on Verizon S5. So why not S6?

I think Band 17 is the issue. Most of AT&T LTE is on Band 17.
I am currently connected to LTE (Band 4) on my Verizon G6, using a AT&T sim.
I used the LTE Discovery app to get this info.
