[Q] Using my Bell S3 on Wind or Mobility city

Hi there, I have the Bell Galaxy S3 I747M and I want to use it for Wind or Mobility City and I'm just wondering what do I have to flash in order for it to work? Thanks a lot.

Normally you would just need to have your phone unlocked so that other carrier's SIM cards will work. BUT your phone isn't fully compatible. If you get any service it would likely be via Roaming agreements they have.
Most Canadian carriers are running HSPA+ service on 850/1900. Your phones radio supports 850/1900/2100 tri-band.
Wind, Mobilicity, and Videotron to my knowledge use the same odd 'AWS' setup that T-Mobile uses: 1700/2100. Those devices (T999[V]) drop LTE support, they have quadband HSPA+/UMTS radios.
So in a nut shell: an unlocked Bell Galaxy S3 may work on Roger's, Telus, or Virgin Mobile (Canada) but not on Wind, Mobilicity, or Videotron. But an unlocked Wind, Mobilicity, Videotron, or T-Mobile Galaxy S3 will likely work on all of those -- but not get LTE.
If you flash e.g. a Wind modem, you may end up with a brick, or it may work. I don't think it'll work but search the forum first if you dare.

it won't work, it doesnt have the 1700 frequency

Using the S3 AT&T on mobility city

My friend came from the u.s and he has an at&t Galaxy S3 and he wants to use it with mobility city in Canada would he be able to?
What would I need to flash?
Thanks.

As far as I'm aware, it's not possible - Mobilicity uses different wireless frequencies than AT&T.
Your friend would be able to use the phone with one of the major carriers (Telus, Rogers, Bell) if the phone is unlocked.
I believe the model you'd be able to use with Mobilicity is the T999 (T-Mobile's?).

All Canadian models the same?

So i hear all the Canadian models are the same. Does this mean that if i get a rogers note 2 and unlock it i will get full lte on telus?
Thanks in advance

To your question: yes.
But there are two models available in Canada: SGH-I317M, which is so to speak the "big three" model: Bell, Rogers, Telus. (Similar to the AT&T model) And the SGH-T889V, which is for Wind, Mobilicity and Videotron. (Similar to the T-Mobile model)

[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.

Question What are "TMB" or "USC" for unlocked phone?

What is the "TMB" and "USC" in these links? Both are for US unlocked phones.
