Can Unlocked AT&T SGS3 work properly on T-Mobile???

I have the opportunity to purchase a new AT&T Samsung Galaxy S3 for a good price. But I have service with T-Mobile. If I get the phone unlocked, will I be able to purchase a T-Mobile Micro Sim and have the phone work correctly?
It is the SGH-i747

Yes

don't follow this.
you will only get EDGE service and it will be terrible. do a search and you'll find more than enough information on people who have asked this same question already.

You will need to be able to hardware mod the phone to accept a GSM sim on top of the hardwired chip.
You'll also need balls of steel.

Thanks.

The sprint note has no accessable sim slot. To "possibly" accomplish this one would need to modify the hardware by adding a sim slot and hack the software.
there is a thread about sone folks attempting this...i have not been following it.

in layman's terms, you can't. if you remove the back cover from your device there is no sim card slot on the sprint variant to insert a sim. the only current wait to use our phones abroad is to use the sprint international plan.

Got it
Thank you all for your help. I sold the phone. I had no choice...

You could buy an AT&T Note to use with Straight Talk. I have one for sale on eBay right now (Note 1, not 2) that I bought for that same reason, but don't have coverage where I live to make it happen. http://www.ebay.com/itm/290826024805?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649

ebay search
note ii sim or search for this one 271090307387
$6.47 swap that plug and play component into place and BAM sim card slot.
either cut a hole in your middle cover OR buy a int middle cover.
also someone is working on a mod solution to keep the 4g AND add a sim card slot
we off course still need to unlock to work on US carriers but maybe its not locked to begin with since they would not have thought of someone swapping parts like this.

very cool. do you know if you can do a similar trick with the ebay sim card holders for the Galaxy S3 (i.e. L710) ? I'm really hoping to buy a sprint GS3, put it on ting, and be able to occasionally take it internationally.
I was about to buy a motorola photon, but the lack of updates is scaring me.
UPDATE: found this thread if you're more into the GS3 http://forum.xda-developers.com/showthread.php?t=2002515

maybe it's just me, but amazing that so many people still believe that phones are compatible with other carriers............if you have Tmobile, AT&T then you're GSM network, Verizon & Sprint are CDMA..............it just bugs me when people ask to get their Sprint phone activated on another carrier (only exception is Cricket). I had someone a couple of days ago who bought a Tmobile version of the Galaxy S3, and wanted to know how to jailbreak it to use on another carrier.

normally you would be absolutely right. but in this specific case and possible with the S3 as well your incorrect.
the Note II and possibly the S3 have full GSM capabilities. Sprint just "corrupted" them on purpose (and should be illegally as well)
with the gizmo from ebay we get a normal sim card slot. now we just need a good hacker/coder to unlock the intentional "block" put in place by sprint to prevent it from seeing US GSM signals from companies other than sprint.
once someone manages to do that we will literally have a phone that could in theory be used on "ANY" US provider and probably any world provider.

based on a search of this and looking at pictures. why would you lose 4g? the lte chip is built on the processor board.

the statement below is 100% correct. the hardware in this phone is fully capable of GSM service. the removed software controls are the problem.

I don't know. Someone posted that the LTE SIM card (a chip on the board) is part of this board. so removing it would remove LTE (disable it)
but if your going SIM your going GSM so can't use sprint LTE anyway. so its not a "huge" deal.

Magic Sim?
I contacted Magic Sim and they said their Elite Micro Sim would work with Sprint. It did not show on the site so I emailed them and they said it would.
FWIW

There's a guy out there that says he can put it on straight talk w/o sim. operates on verizon network. 231 something was the name of the outfit. google a bit and I'm sure you will find him. hope I helped

look on ebay at the people that do boost mobile flashes for the note 2. send them a message asking if they do the sprint note 2 to straight talk. most of them I talked to do this for like $50 if you have a new donor. If anyone needs more info pm me and I'll be glad to help

If it has the 'Sprint' logo painted on it, you may not be able to use it on AT&T.
I suggest call AT&T first, to see 'if' you can...
then proceed from there.
wish I could help.. sorry

on what carrier you are planing to use it? You cannot use sprint Galaxy note 4 on domestic GSM carriers like AT&T, T-mobile and their MVNOs (Straighttalk , etc). The phone can be unlocked for international GSM use (voice and 3G only, not LTE). Internationla unlock can be done officially through Sprint or unofficially via app in this thread:
http://forum.xda-developers.com/spr...print-samsung-unlocker-unlock-sprint-t2928250

My question is how did you come across a Sprint Note 4? Did you not do your homework before acquiring the Sprint Note 4? Maybe you somehow got the phone for free? Why would somebody actually pay for a nice phone (released only a month or so ago) without knowing if it will work on a completely different network/carrier... then turn around and look for help on how to activate it on a GSM carrier? This makes no sense to me.

Im curious too.
Can a Sprint phone be unlocked and set up for use on ANY other carrier in the USA,
ie: Verizon?

No no no

I am pretty sure that if the phone had a clean ESN that you can activate it on Ting Mobile. I have also saw a thread where someone had flashed a T-Mobile Rom to the Sprint note 4 but they where not getting LTE of course I'm sure in time someone will come out with something stable.

Off topic here.
I came up for upgrade in June. I was gonna go Nexus 5 and then the Nexus 6 rumors started to fly. So I waited and along came the Note 4. After much research I ended up with arguably the best phone on the planet. Imo it is.

Unlock Code
I am in Canada, got this as xmas gift from my father in law

You can root and try Galaxy Tools 4 root users https://play.google.com/store/apps/details?id=com.idone.galaxymenu
Or you can use this app from the S5 thread you don't need root with this app http://forum.xda-developers.com/showthread.php?t=2928250
Hope this helps a little

1. No
2. Customers can switch devices by calling on a different phone to CS or going into store and switch devices, no unlocking necessary.
3. Just switch Sim cards and edit and tweak where necessary or pay someone if you dont know how.
4. Correct, but no unlocking necessary.
5. That depends on the person.

Thank you for your answers

Yes yes yes it can be used with other carriers in the USA. Are people forgetting about flashing of modems and firmware. What decade are we in 1960? Our maybe 1950 when phone were still two way radios. Remember sprint can't stop everything Samsung does in making their phone. Ask the right questions to right people get right answer. If someone in XDA hasn't figured it out yet just wait & keep on looking. XDA is also not the only place to look for answers to everything Samsung, sometimes Samsung is were to look or Samsung blogs. All I hear is everyone that talks about Samsung first thing everyone says is it CAN'T be done. When are the tech, crackers, & hackers of this world going to stop saying everything is impossible & realize we are the ones that make everything possible. If we are going to do that why do we become techs or crackers or hackers or even developers in the every first place?.... LET'S STOP PUTTING LIMITS ON OU OURSELVES & SHOW SPRING WHAT WE CAN DO! Sprint is not GODZ. We created what sprint & Every carrier in the world uses to try to put limitations one everyone with. Are we going to let the carriers use or phones against us or are we going to use them the way the phone manufactures wanted the phones to be used ( without restrictions of the carriers of the world.)

after unlocking your sprint device you can only use it with carriers outside the USA. If you are planning to use it with local sim cards after unlocking like at&t and t-mobile (gsm) then you cannot.

Umm if its not under payments u can

Yep once the phone is paid for per new laws that went active in Feb or March if you ask the carrier to domestic unlock your phone they are required to do it by law. Some models this will not be possible but the note 4 should. I think the carriers have a grace period to make this available. Not sure how long. I could quote the legislation but Id have to search for it.

B to the S. If you can unlock a 720t a note 4 can be unlocked!! Period!! It picks up signal just no antenna for that signal because the phone antenna is tuned in the wrong station or radius degree. I think if the people who can unlock 720t s can try the same methods with busy box or Verizon modems. Like guy said earlier " Si se puede"!! It can be done!! Just need to tweak frequency angles and remove face security options a little.

By law you can have it unlocked for a limited time, but that will not make the LTE radio magically work on your carriers band unless they support the same band. Or unless you know someone who can JTAG flash the radio to another carrier as well you will not be able to use the LTE/DATA band on a carrier that does not support the frequency. This is nothing something that can be done over USB or by a new kernel. This will have to be done with JTAG and by someone who has access to the various carriers radio firmware which is tightly guarded. So basically you will be using a Note 4 on 3G only. Might as well just sign up with SPRINT then, you will get the same service speed.
