Differences

What is the major differences between Bell, Rogers and AT&T? Other than the M at the end of i747M vs AT&T i747? Looking at specs on all but Bell gets same as AT&T + has AWS( T-Mobile )?
Also would you treat all as AT&T or International for Bell & Rogers?
And if so cam you turn the Bell & Rogers into an AT&T? Or is it already just with Bell and Rogers programming in it?

If you are an AT&T subscriber, have an AT&T MicroSIM card and are traveling to Canada for a short period of time, you don't have to SIM-unlock your phone. You can use your actual AT&T MicroSIM card to roam on Canadian's wireless networks; you keep your actual contract with your carrier and keep your actual phone number. Beware of the potentially high roaming fees your carrier will charge you, though.
But if you plan to stay in Canada (either you are moving to/living in Canada or are traveling to Canada for an extended period of time) and you would like a new Canadian phone number in order to avoid the roaming fees, then yes, you will need to buy a new MicroSIM card from Rogers and yes, you will have to SIM-unclock your phone in order for your phone to recognize another carrier's SIM card.

[Q] TMO S3 on Straight Talk on AT&T, can I do this?

I would like to use my T-Mobile Galaxy S3 on Straight Talk on the AT&T network. I'm currently using Solavei running under T-Mobile's network, but T-Mobile isn't cutting it in my area. I really want to run on the AT&T network. Solavei only runs on TMO.
TMO is great when I can get 4G but it sucks when others in the same physical location can get AT&T to 4G and TMO is E or G network.
Examples of where AT&T is working great but TMO isn't are: up in the canyons (Millcreek, SLC, Utah), over the dunes at the beach (Topsail, NC), at my house (SLC, UT).
Questions:
1. Can I do this? Run a T-Mobile Galaxy S3 on Straight Talk on the AT&T network?
2. If so, If I buy a sim from Straight Talk what does it take to make sure it runs on the AT&T network and not on TMO? I'd really hate to go through all that and still end up on TMO and not AT&T. I've already had an AT&T sim running in my Galaxy S3 and everything was working great. I just didn't want to pay AT&T prices.
3. I've heard that Straight Talk will switch from TMO to AT&T depending on what area on the country you live in. Is this true? Is there anyway to override this?
4. I've heard that you can't buy AT&T sims anymore from Straight Talk. There seems to be a market now for AT&T sims that were available at the beginning of the year but are not now.
PS: I'm trying to do this for the TMO Note 2 also.
Yeah you can use tmobile's straight talk on at&t network. Just pop in sim and select roaming and available network select at&t. Should connect no problem

You have to SIM unlock your phone first as it won't take an at&t SIM out of the gate - either call T-Mobile for the code or you can follow this method - http://forum.xda-developers.com/showthread.php?t=2023709
Note that if you are the latest radio (MD5), you will have to downgrade it to LJC or LJA for the radio unlock option to appear - the radio images can be found here - http://forum.xda-developers.com/showthread.php?t=1880987
That trick works on the Note 2 as well, however, I don't know if the radio is an issue with the Note 2 you will have to check the Note 2 forum but chances are if Samsung updated it, you will have to downgrade the radio to get the option back.
StraightTalk will not sell you a SIM for at&t if you don't have at&t service in the area - at&t's StraightTalk SIM does not roam on T-Mobile except rarely as at&t's roaming agreement with T-Mobile is extremely limited.
One final thing, I wish you good luck. StraightTalk was a horrible experience for me and at&t throttles you like nobody's business. On the plus side though, Tracfone's wholesale contract with at&t means that you get access to their POSTPAID network which means you get better coverage than at&t's own prepaid or any other MVNO of at&t for that matter.

This is not what the OP was asking. He wants to switch his T-Mobile branded S3 with T-Mobile branded service to StraightTalk using an at&t SIM and service.

[Q] Unlocked phone on Verizon's network

I have a previously AT&T branded Galaxy S III that has been unlocked. I currently use this phone for my international travels and I was wondering if it is possible for this phone to work on my Verizon line. It is currently rooted
No, Verizon is CDMA while AT&T is GSM. Not compatible.

Cricket wireless

I have a Samsung Galaxy s3. I plan on making Cricket wireless as my carrier. They are affiliated with AT&T. My question is how will i be able to root and flash roms with Cricket as my carrier? Do I use the AT&T thread for the s3? Anyone's help would be appreciated.
Cricket is indeed a At&t subsidiary so by all means a att s3 will work on cricket. And just continue to use your phone as you normally would......just keep those cricket apns with ya and the cricket Sim and you should be golden.....and yes if you have a att s3 then continue using att Roms like you normally would
