Can Unlocked AT&T SGS3 work properly on T-Mobile??? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

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.

[Q] Unlocked Samsung Galaxy Nexus GT-I9250 bought from google play store

Hello I just bought an unlocked samsung galaxy nexus GT-I9250 and I have a couple of questions #1 has anyone successfully registered their galaxy nexus with samsung. If so I need help. I found the serial number and typed it in along with the purchase date it tells there is an error. #2 does anyone know where to download the drivers for the unlocked galaxy nexus? please give me a link. And last #3 is there some apn I need to put in to get the phone to connect to AT&T's HSPA+ network. Please help. this is my first nexus phone.
1) I can't answer because I imported mine.
2) Here are the drivers. http://forum.xda-developers.com/showpost.php?p=20058157&postcount=1
3) I'm on T-Mobile so I don't know for sure but, I believe you have to call them to provision HSPA+
You can't register it with Samsung.
am i supposed to register it. if so then who?

They're Beta because they're universal. There's official drivers that are specifially for the Galaxy Nexus, but they're tricky to install if you're not familiar with computers.
As for your first question, I tried, couldn't either. Doesn't really matter though, as I called them up for a warranty repair (got some water in the power button) and when asked for my IMEI number, they knew the day it was purchased and shipped.

You don't need to register the phone, all warranty claims can be made through Google, just tell them the Checkout Account you used to purchase the phone. AT&T will need to provision you a "4G" plan, which requires the IMEI of an AT&T "4G" phone. Go in store and they should be able to use a floor model or some unit that they have laying around back, don't bother calling Customer Service, they won't know what to do. No fancy APNs to deal with, just crap AT&T mobile registration (even for prepaid).

I have a 2 gig plan that I got when I upgraded to the inspire and never saw HSPA+ not even in settings. I saw on YouTube a video and a guy had gotten an LTE plan. But I tried changing my plan online but seeing how att doesn't recognize the phone I couldn't. Do I need to try an lte plan? I have been places that supposedly have HSPA+ but was always on hsdpa and att said "HSDPA is more enhanced version of HSPA+" which I know isn't true.

I know that I'm not stupid. I'm just wandering why I never get HSPA+. I didn't get it when I had an inspire 4g and i still don't get it with the galaxy nexus. I still have HSDPA. And I've gotten HSDPA where there is supposedly "4G" for example Atalanta.

[Q] Sprint Galaxy Note 2 Unlocking

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.

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

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.

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.

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

While this is excellent news, whatever the method is will not work on the AT&T variant.
This is a major deciding factor for me on getting the Note 4. Root is a must have just for AdAway and Xposed.

Because AT&T locks down all of their bootloaders. This makes it nearly impossible to root or flash custom roms. They've been doing this since last summer with the Galaxy S4.
Ya unfortunately. ATT's phone's for the most part have been rooted by geohots. Who now... Works for Google to fix the exploits for possible rooting. The ATT G3 was able to get rooted by Towelroot, I hope the same goes for Note 4... but I doubt it.
Yes, this is only for note 4's with unlocked bootloaders. It will not work on AT&T's or Verizon's. Possibly good news for the T-Mobile version though, as soon as we can get a stock rom dump to chainfire.
BTW: I would change my subject line OP so people don't get confused.
This is the first phone I have paid for not under contract. So as I started doing research u read about AT&T locking the bootloader. So last night I preordered the T-mobile phone just to have this ability. I did have to sign up for $50 a month just to be a customer but I will be a customer. I will cancel after the first month.

This will be my first time I am trying to convert a phone from one carrier to another. when I get the phone will I be able to just stick my existing AT&T sim card in to it and it work or will I have to wait for the 40 days and ask tmo to unlock it?
I know the iPhone 6/6+ came unlocked for tmo and you could just stick the AT&T sim card directly in to it and it would work.

From what I've gathered from the note 3 threads, we will most likely have to pay a website a fee to get an unlock code if we don't want to wait 40 days on contract for tmobile to do it. Chainfire released an app that had a "side effect" of carrier unlocking the sim for the Note 3. Whether that happens with the Note 4 remains to be seen. I'm just going to assume I'll have to pay a fee to an unlocking website.

I've had an htc one m7 with att and then wanted to sell it to a guy on craigslist who had t-mobile. you must sim unlock the device, it's a code. Just tell at&t or tmobile that you have a trip going to europe and need the phone unlocked to be able to use it. Then they will give you the unlock code. Put in the att sim card it will ask for a code then put it in.
What I did was I paid a guy on ebay 4$ to get the code and I got it within 5 seconds att was taking too long and the guy wanted the phone that day.

No one will know for certain until the phones actually come out, but if you go by the cellular bands announced for the T-Mobile version, it should work.

No, and don't try it either.
CF-ROOT won't ever work on AT&T Note 4 because it requires an unlocked bootloader to achieve it.

Is the AT&T bootloader def locked?
Won't be able to tell you until tomorrow
For all of you who are freaking out about it being a locked bootloader...so was the LG G3 for AT&T...we just got TWRP on it last week. Took 3 months but it is doable from the right people.
It was called "Bump" and I have tested the unlock myself with full custom twrp recovery & root.

Usually your carrier will do that at no cost, it might depend on how long you've been with them, contract duration, contract remaining... I would give them a call and ask, I've done it a couple times in the past with AT&T without issues

Sure hope he got Sprint to unlock it for you before he left. Because if not, you'll have fun getting it to accept your att sim card.
If the unlock is done already you should be able to factory reset and insert your sim card and it should detect and customize for att settings.

Moving across the globe won't prevent your friend from getting a hold of Sprint and requesting the device to be unlocked.
Try getting in touch with him and ask him to take care of it. As long as the device qualifies for unlocking with Sprint then this shouldn't be an issue.

Is the phone network/sim unlocked? If it is then the process on how to do this has been covered indepth already. Be aware though that some features will only be provisioned to phone's that AT&T sells (they determine this by an IMEI whitelist). This also has been discussed extensively on the forum.
If your phone is not sim/network unlocked then you will be wasting your time as it will only work on the Sprint network. At this point get a hold of your friend who gave you the phone and ask him to get a hold of Sprint. Your friend will need to ask Sprint to unlock the phone, provided the phone qualifies to be network/sim unlocked by Sprint.
