[Q] Modem differences - AT&T Samsung Galaxy Note II

Hi guys,
Just bought an AT&T SGN2 and loving it.
The thing is, I'm here in the US on business and live in Canada on the Fido/Rogers network.
Now as I understand it, there is a Rogers specific firmware available which has a different modem than the AT&T firmware.
What is the difference? Any benefit to switch?
AT&T and Rogers use the same frequencies for 3G and LTE, so why different modems?
Thanks

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?).

[Q] SGH-I747M - Unlocking and changing carrier networks

Hello guys! I'm using the I747M variant which I bought from Rogers about 8 months ago and I want to know if I can switch to other carriers network here in Canada via unlocking because Rogers' available phone plans are just a pain in the ass so I want to switch networks. So please kindly share any information regarding unlocking and changing carrier networks. Thanks in advance

Once unlocked, It is guaranteed to work with Bell and Telus.
Hope this helps :good:
Search for it, it's around here in the forums for free. You just need a simcard from the next provider you wish to go to.

How about on other networks such as Mobilicity? My mom is on a plan on Mobilicity and I also want the same plan because my phone is kinda useless without internet and not even a caller ID.
once unlocked it'd most likely work
but for the data part, i can't really say because different mhz on different carrier network..
so 70% chance that you will only get Edge in your area
Does anyone knows any information on how to change radio frequencies on a phone? I've seen some SG3 on ebay.ca that is labelled as "Pentaband" and could work with any carrier network here in Canada. Can someone please explain to me how does this work? And is it possible for my phone to be converted into a "Pentaband" phone?
Mobilicity does not use the same bands as Rogers, Bell or Telus for its HSPA/HSPA+ service. As Pcshano said, your phone would work on Mobilicity, but only on Edge.
You encounter the same problem as T-Mobile users in the US, and WIND and Videotron in Canada. See [WIP][BOUNTY] Enable 3G on 1700MHz for ATT Galaxy S3 i747 on efforts to enable HSPA on 1700MHz on the i747.

[Q] N7105 or SGH-T889V???

Hi there,
It started with when I bought int. version N7100 from Amazon.com. I live in Canada and use WIND mobile. So I inserted my SIM and it didn't work! I sent Note 2 back to the seller, and get refunded soon. So, basically, I'm sort of noob here, and have a noob question. Sorry, but need your help.
Now, I want to give a try to purchase N7105 or SGH-T889V (from Mobilcity, cuz it is cheaper) version, and use it with my WIND sim card.
1) Will N7105 work with WIND AWS band right away or do I have to root and flash WIND modem for it?
2) Same question as in 1) but for Mobilcity Note 2 (but I guess it will work right away without any software modification. I want just to make sure).
3) After 3-4 months I'm moving to USA (more likely) or Europe (depending my job offer), and going to get sim card from some local carrier. Which model, N7105 or SGH-T889V, covers more network?
4) As far as I understand SGH-T889V fully supports what N7105 supports, but not vice versa, am I right?
If you want to use your Note 2 on Wind then the T889V is the one you want. It's also possible to flash a radio hack on the Bell/Rogers/Telus version to get AWS HSPA. However, the T889V does not have LTE officially.
For travelling, , 7105 will be your best bet in Europe as it will support every carrier there and you will get LTE if the carriers support it. The T889V will be better for the States as it supports AWS HSPA on Tmobile, however still no LTE.

I saw on the internet people using N7105 with Bell, Telus, and Rogers with full LTE potential. And my question 1) still holds. Is it possible to do that? Even if it is possible, will it be same quality connection/performance as native (T889V) Note2?
But according wikipeadia, T889V supports some LTE bands. Maybe after flashing the modem, as you said, it will be compatible Bell/Rogers/Telus.
Now, I'm coming to conclusion that both of them work with almost all major North American carrier with full potential, while N7105 also is gonna support EU carriers. So, it is sort of N7105 > SGH-T889V, i.e. is N7105 way to go?

[Q] Carrier Variants (Freq/Bands)

I'm looking into picking up a G3, and I'd like to use it on GSM networks in the US. T-Mobile, maybe AT&T at some point. I'm unfamiliar with G3 hardware, so I'm wondering if either the T-Mobile or AT&T variant have more compatibility than the other, so I know which one is generally preferred to get.
Thanks!
Nobody?
Get D855. It is international. It will work with GSM network.
