Unlocking T-Mobile for AT&T service

hi everyone:
I have been looking via numerous thread online on many Android forums especially here and have been unsuccessful for the past 2 days now. So I figured I would need to create a thread and finally give in and ask for some help. I have a T-Mobile Samsung Galaxy 3 phone and I need to unlock it so that it will work on my AT&T service. Now i understand about rooting the phone and being able to play with themes etc, but its not that great if I can't use the phone itself.
Now without coming up with some kind of answer I must have watched about 40 youtube video's hoping to find out some kind of information. Mostly what I got out of it was numerous website that offer unlocking for phones at a certain price.
unlockcodesource(.)com
unlock2go(.)com
mobileunlockcodes(.)co.uk
Has anyone ever used any of these website or can someone give me some good advise on how I can get this phone unlocked please/

I think the toolkit stickied in the development forum has an option to SIM unlock the GS3. I have not tried this, and do not know if it works, but if the option is there, you might want to give it a shot.

If you're on contract with t mobile and your account is in good standing with them. Call them tell them you're going over seas and need to unlock your phone so you can use it. They will send you unlock code ... then pop in an att sim card and it will prompt you to enter the unlock code t Mobil gave you. Done

OK thank you. I followed your instructions and they said it would take up to maybe 24 hrs for the phone to be unlocked. If it isn't unlocked than she said to call back with the conformation number she gave me. If that doesn't work than they would have to give Samsung my info and could take up to 14 days. She said when you buy phones almost all stands and corp stores have already unlocked phones.
she also said it would be auto unlocked for good. Can they lock the phone back up once it is be unlocked?

edited: Once I have it unlocked ( if all goes good ) do i use the same APN settings that I needed to put into the phone in order for my phone to work on the AT&T network as I did with my S2 that I got unlocked ?

Don't they use different frequencies for HSPA+
You would be relegated to edge speeds, correct me if I'm wrong

I really don't know. That would be a great question if someone would be nice enough to help me with this information? Again i have a T mobile S3 hopefully its unlocked would I be losing speeds by being on the AT&T network?

The T-Mobile S3 has the 850/1900 3G bands so it will work on AT&T's 3G network. It will not get LTE though.
You can unlock either by paying for a code from the various resellers online or requesting an unlock code from T-Mobile if you have an account in good standing with them. If you can't get the code from T-Mobile I suggest searching 'T999 unlock' on eBay and you'll find some good options.

The tmobile galaxy s3 will work on the ATnT HSPA+21 frequency. Same frequency the International version runs on for that network.

Edge network and 3/4G Question
I found an excellent place so far on eBay for buying unlock codes. they have almost 3800 sells with a 99% positive feedback. Great customer service. The guy answered numerous questions of mine and made sure i did everything correctly. Payment was $24.95 US, so hopefullly everything will go good.
He was talking about being on something called an " Edge " network which is a little slower, but he said you won't notice a difference between your unlocked S2 and the unlocked S3 now. Right now my S2 says I have 3G service when I use it. I dont understand how i had a inspire4G, what is the 4G for if AT&T only gives you 3G service? And where I am in United States I should have 4G service no matter what. I'm confused on that.,

Edge is 2G speeds, which are substantially slower than 3G speeds. IMHO, 3G speeds are livable, 2G/Edge is not.
Different phones have different radios which work on different frequencies. Some phones are not compatible with other services at all, and some will work on other carriers but often not at optimal speeds.

So than why would someone suggest that I would get "edge" instead of what i have now? I'm getting 3G now with my T-Mobile S2 unlocked on AT&T, but now I'm going to have an unlocked S3, why wouldn't it be the same?

Because the radios in the devices are different.

Because he/she doesn't know what he/she is talking about. You will be fine with a T-Mobile S3 on AT&T.

That's what I said earlier in not so many words.
Voice willl work fine you will not see HSPA+ speeds on At&t with a T-Mobile Galaxy SIII.
If the T-Mobile SIII has the hardware capability to support the At&t HSPA+ bands you would need modified radio software to unlock this ability.
I believe this was done on the Galaxy Note to tun on T-Mobile HSPA+ network before it was officially launched on T-Mobile.
kmdub I believe your the one that's wrong.

I unlocked my t999 and am using an att straight talk sim getting HSPA speeds. Going to switch back to tmobile prepay because it is way faster than att HSPA with better latency. Although coverage may be lacking, i may just switch to an att ST sim.
To answer your question, a Tmobile S3 will work on ATT HSPA+ network with the HSPA+ Speeds of up to 6-7mbps in NYC area. The average I've been getting is around 2-3.5 mbps. With the tmobile prepay sim I have, it's usually around 2-18mbps down in NYC area.
The T-mobile S3 will not work on the ATT LTE network because it lacks that radio (or so they say for now); there have been other threads suspecting it's just a matter of flashing the right radio to "turn on" the ATT LTE radio. However, if all you want is HSPA+ speeds, rest assured it will work fine.
The ATT S3 is lacking the AWS bands for TMobile so it will not get the HSPA+ on Tmobile.
Best regards.

radio issue
First off, I would like to thank everyone who has been helping me along with my issues with my phone. I appreciate it a lot and I'm picking up more knowledge more and more everyday from you guys and reading heavily on the forums.
if the hardware in the phone doesn't support HSPA+ 1) will i have to root the phone and 2) change the radio? And 3 ) if I change the radio does that mean I would need to install a custom ROM i order for it to work properly?
Also, from one of the post they said "The T-Mobile S3 has the 850/1900 3G bands " - of that is true will than I should be able to have the 3G speeds correct?
I really hope I am not making some people angry, I'm new to this and trying my hardest to understand everything so I don't make mistakes. Please bare with me. Again, thank you so much everyone who has contributed so far. I still have a lot to learn. The reason why is because I just don't want it to work ( I do, want it to work ) but I want to understand why everything is working they way it is and I've over the past almost month have been picking up a lot of knowledge. Can't wait to hear from you guys

kmdub I believe your the one that's wrong.

No, actually, you are wrong. The T-Mobile S3 does not need any modification to work properly on AT&T's HSPA network. Seems you are confusing something else with frequency. Quit spreading bad information.
OP: Don't worry about it. Some are making this way more complicated than it needs to be. As said before, if you have the T999, you will be fine on AT&T's HSPA network without any modifications (other than an account...lol). Just get the phone SIM-unlocked, pop in the right SIM, you are good to go. Seriously, it is that easy.

Well there it is, I stand corrected!
I had no idea the T-Mobile SIII supports At&t HSPA+ bands.
Is the same true to all T-Mobile HSPA+ phones?

Sorry for any issues, just learning
Hi everyone,
thanks so much for the info. Will the S2 I needed to put in certain APN settings inorder to receive MMS ( picture ) via texts. Do i use the same settings for the Samsung Galaxy 3?

[Q] Force Roaming GSM Networks

My phone service, (i wireless), has mostly EDGE in the service area which really pisses me off.
I live in Garner and sadly I can't user Verizon's LTE which is available in the area because it is CDMA.
Anyway, I'm usually in a town which has AT&T in it (not Garner) and they offer 3G/4G.
I don't care if you think AT&T isn't the best, or is slow.
i wireless is having major network improvements this year and until I get 4G; I want AT&T.
How can I acquire their service, I want to force roam to them.
Can someone tell me how to do this?
I am running Android 4.1.2 (CM10).
Thanks!

http://forum.xda-developers.com/sitesearch.php?q=force roam at&t

WOAH ZOMG SO HELPFUL.
Honestly, that was really helpful.
I've already searched; that's why I'm asking here.
I've tried other methods.
Most force roaming is with CDMA networks.
Thanks for being so helpful.
Someone who actually knows help me please!

Can anyone help me?

your APN settings are tied to the simcard.
the phone has nothing to do with roaming, your sim determines where you can and cant access towers (except for emergency calls, those are always allowed)

Yeah I know that.
But even if there's nothing but AT&T for a service and I try and select it, it won't work.
Changing my APN settings could work, but idk.

you need a sim that connects to the ATT network. you are using a provider that uses tmobile.
you're trying to do something with the phone that has NOTHING to do with the phone.
EDIT: also if you want 4g LTE through att, you will never have it as the phone does not support LTE in the GSM variant.

I'm not an idiot, I thought that that was common sense.
I want 4G HSPA+.
T-Mobile is a priority.
You can use AT&T still.
When I tried roaming to it though it wouldn't accept it.

i never called you an idiot so dont get all defensive.
prepaid plans generally do not let you roam. if they do, its usually voice only.

I didn't mean to come off defensive, I'm just tired.
My plan isn't prepaid either, it's post paid.
AT&T comes up as a network option and I have used it before on previous phones.

Did you ever get this figured out? I have the exact same problem as you. I also have iwireless and have the slow 2g when 4g signal is low. I am looking to force roam on AT&T when I don't have iwireless 4g. Hoping to hear back. Thanks

I go to chrome loop up a page get "error 502 bad request the server could not resolve your request", i have full bars and H+ but wont connect. I also notice that when i insert the sim i can just pull it out with out pressing down on it. Any help...

I know the ZL (6506) is capable of working with T-Mobile's new LTE network, but my question concerns the IMEI number and your account with T-Mobile. On AT&T, your account has to have an IMEI number that is known and recognized by AT&T so as to enable LTE connectivity. Is this also the case with T-Mobile??

The info or where you got your info is incorrect. you DONT have to have a IMEI number that is known to AT&T to have LTE. I have changed phones prob 20 times since I got my first LTE phone and NEVER had to change it again.
You can be on the LTE data plan and everything work fine on a old dumb edge phone then put the sim card back in an LTE device and it still work fine...
LTE worked fine on a Canda Note 2 and One X

Same here. TMo does not care. I just started using my ZL teo days ago, before that was Nexus 4. Just took the SIM from the N4 and inserted in the ZL. All works!

Hey people, I'm seriously considering picking up a Sony Xperia ZL C6502 Black. I'm aware that it doesnt support LTE on either network, but the price is insanely lowwww! My question is, does anyone know what kind of speeds I can expect to see on TMO and ATT respectively? I'm currently using an ATT Gnote 2 on ST/ATT and I have a Nexus 4 as a backup which I use on the TMO $30/"unlimited" data plan. I only point this out to indicate that I don't get LTE speeds now, which sorta makes it a "You can't miss what you never had" type of deal. I roughly get about 14-17mbs down on either device. Is there any chance I'd enjoy the same with the 6502 on either of these plans??? Any help/insight or even opinions, would be greatly appreciated.

The speeds to expect will be the same as you have now.......

i just received my ZL C6502 today and noticed that the data connection does not work at all. i followed the APN settings on the t-mobile link you gave and still no dice (it does show full bars and H+ as you mentioned and when i switch the SIM to my old G2X its on full HSPA+ speed). i left the house and it was running ok suddenly and streamed netflix, etc. but when i went home it lost the connection again. I'm suspecting that this phone does not really work on t-mo's 1700 AWS even though the box says so and that i only got online outside the house because that area is on the 1900mhz refarm. is there any difference to t-mo's AWS 1700 and regular HSPA 1700mhz?! any insight or help is appreciated!!

I have a 6506 on TMo so I am limited in help. However, someone in my office has a 6502 on TMo and it is working fine. He had trouble until he manually set it. Same case as mine.
Perhaps you have a defective unit? Try removing and reinserting the SIM card. Perhaps a factory reset.
I had mine for almost a month and has been flawless in LTE when in DC and HSPA in Dallas.
Sendt fra min ZL 6506

The 6502 is the same as 6506 but without lte it should work I don't have 1900 coverage and I'm always on hspa and there's no lte were I'm at either. U need to make sure the apn is set exactly there should not be any values under proxy and port also under apn type have it blank that was the issue with mine those three things had values and was messing up internet. Also there's three different apn you have use. 1. Fast.tmobile.com (Lte), 2. Epc.tmobile.com, 3. Internet2.voicestream.com. Give it a try.

thanks for the help guys. ive gathered all that info earlier and did try the three APNs different combinations / proxy - no proxy, etc to no avail. i'm leaning on faulty hardware or messed up radio. i'll just sleep over it but so far its been disappointing :crying: great phone though...

As a quick update I did literally sleep over it and I'm happily up and running with hspa.. I literally left the phone alone overnight lol. Rooted the fone and all I need is to figure out how to get to recovery to put CWM since pressing vol up at boot is not working and flashboot isnt going either (that's for another post). Moody bastard this ZL is.. Anyway Thanks again!

I have a 6506 on TMo without any issues. I live in LA without TMo LTE, but speeds have been as high as 18Mbps in West LA. I only have the issues of bad coverage at my house, but that's just TMo and not the phone.

That's the thing you had an LTE phone AT&T had in their system when your account was provisioned for LTE so you never had a problem after that. For those people that have the ZL as their first LTE phone on AT&T they will have to first get the account setup for LTE using a phone AT&T recognizes on their network.
So basically put the SIM in an AT&T LTE phone, have AT&T provision it for LTE then once that's done you can put it in any other LTE phone and it will work fine

S4 mini LTE only H+ not 4G

In my s4 mini i cannot get 4G signal, only H+. And i am in 4G zone. Anyone have this issue? Thanks

Nope, I am in Singapore and do not have this issue. Are you on stock ROM?
S4 Mini's LTE radio supports:
LTE Band 3 (1,800MHz), Band 7 (2,600MHz), Band 8 (900MHz), Band 20 (800MHz)
[Source]
Vodafone Portugal supports Band 20 (800MHz), Band 3 (180 MHz) and Band 7 (2600MHz)

So it should work.

I have a somewhat similar problem of owning an s4 mini but only getting HSPA+ (icon "H+" in the status bar) and not 4G LTE (icon "4G"). In fact, since I purchased the unit in late July, I have *never* to my knowledge had 4G service, only HSPA+. The key difference from the OP is that I am in the U.S., have T-Mobile as my carrier, and my s4 mini is an unlocked unit. Has anyone else bought an unlocked s4 mini for the U.S. market and not been able to achieve 4G LTE?
T-Mobile offers 4G LTE in my area (Detroit area), and I have also used the phone in Hawaii, Los Angeles, San Francisco, and Portland, OR. In none of these places have I attained 4G LTE service.
At first, T-Mobile said that the phone probably operates on incompatible bands with their network. But I confirmed that the 4G LTE bands used by T-mobile are supported by the s4 mini. So back to why no 4G LTE??? Any advice would be great appreciated. Love everything about the phone, except for the disappointment of having expected to have 4G LTE on my newly purchased phone.

I have the same problem in Vodafone PT, when I called the customer service, they tried to make an elaborate excuse that 4G signal was being displayed as H+ on S4 mini.
And by now I know it´s a lie.
Can you share what you did?

Yes it is a lie. I called the customer service and they told me that my SIM CARD wasn't 4G so they send me another to my home (or you can go get one in a store). Then the problem persisted, so i called them again and they said that they needed to activate the 4G in my service. In one hour i get 4G on S4 Mini.
Maybe your problem is on the SIM CARD... Try to go to a store.
And see in this page if the location where you are trying to use 4G is covered: http://www.vodafone.pt/main/Ajuda/Cobertura/

At first I saw thought that two, but after recieving the 4G ready sim card, the problem persists.
I´m gonna call them again.
Thank you very much for your help.

"Update: I just called the customer service again, and in fact they told me the 4G service was not active on my account. In one hour I should have 4G."

Call customer service again, they may have not activated the 4G on your account... If they do try to restart the phone.

Unlocking 4G service on n910p Outside the USA

Hi
i have a couple of questions here , how can i access USB settings on n910p
cyanogenmod rom 5.1.1
becuse i want to try this on it .
and i want to know is the phone hardware locked when it comes to the frequency it supports ?
becuse we have LTE B3 (1800) in my Country , and the phone supporte LTE band 2(1900), 4(1700/2100), 5(850), 12(700), 17(700)
so i want to try and unlock the 4g service if it's possible.

Let me give you an insight about your query...
1. I'm too using an unlocked N910P with a GSM SIM like you where the 4G bands present in my country are not supported by this phone's hardware.
2. I've tried the post that you are referring to in the past but wasn't able to do anything because the software QSPT couldn't find my phone. Tried several times but with no success.
3. You can access USB Settings using Iodene Tools or Galaxy Tools. It has now become a paid software so the developer has removed it from XDA. (Search on XDA to find some threads related to it. You might get help from someone).
In short, it's almost next to impossible to unlock the bands as there's a high possibility that some tempering must have been done with the motherboard to unlock it, especially if the phone you got came with some Chinese firmware on it.
You can always try to check if it works for you or not.

Thank you for your explanations. I have something to ask.
I bought N910P. It was on Lollipop and 4G/LTE network was fine. But then I upgraded to Marshmallow via Odin. And now, there's only 3G with setting already to 4G/LTE. What is this problem related to?
Thanks.

See, the 4G icon that you witnessed after purchasing N910P was just a false indication. In reality, the network was 3G. Even when I got this phone, it was on Lollipop and it used to show 4G and the funny part was that I wasn't even using 4G then.
I've seen many users getting confused regarding this matter.
The only option available is that the network providers of your country start 4G services in the band that is supported in US (which again is highly u).

That 4G icon you were seeing was just HSPA+ but not actually 4G. If you see LTE then you can assume that you are on actual 4G.
