Anybody using a T-mobile SGS 3 on At&T?

I'm reading that the GSM variants have IDENTICAL hardware, meaning if unlocked I can get LTE on a T-Mobile device while on At&T's network.
Can anyone clarify?
I think you can get lte and edge, but no 3g. I think.
not working right now
edge working but in roaming mode
and also no calling

[Q] Will an ATT or Rogers Note 2 work on more thna edge speeds on T-mobile?

I just received my Note 2 it is on Rogers.
I have unlocked it but it is not yet rooted.
I have just traveled to US and am using my T-mobile SIM card and no matter what settings I try I can't get anything other than EDGE data even though I am paying for 4g.
I was under the impression that All models of the note 2 In North America (not including Verizon) were identical and would if unlocked work on all networks equally.
Seems this is not the case. The TMobile site lists different choice for the LTE bands than Rogers. Yet the Telus branded model on their website shows the same version of LTE as on Tmobile.
Are the phones actually different? Or is it the firmware of the Radio inside such that if I rooted and flashed the Tmobile modem it would then allow me to use the faster speed data network on my unlocked Rogers phone but on the T-mobile network?
No. Our model doesn't support the frequency that T-Mobile uses for 3G

Is it possible to flash the modem for Tmobile on ours and make it work?
I was under the impression all the phones in Canada were identical and yet the Telus one seems to have different LTE frequencies so maybe it just needs to be enabled as hardware not firmware supports it

No the hardware doesn't support it so a different modem wouldn't work. Our phones (Bell, Telus, Rogers) support LTE on 1700/2100, but not HSPA+, so until T-Mobile launches their LTE network you'll be on edge only
Edit: There are some areas where they are reforming their 1900 spectrum to HSPA+, so you could only connect in an area where they have done that already

So I guess for now I will stay on EDGE hopefully LTE goes live soon enough. The Rogers phone will work on their LTE frequencies right?

T-Mobile Note 2 on Wind and Bell Mobility

Hello all,
Thinking about buying the T-Mobile Note 2 which I plan to use on my T-Mobile prepaid line. But also use with my 2 accounts in Canada on Bell Mobility and Wind Mobile, if I get the T-Mobile Note 2 and unlock it, will I have any issues using it on either on these two Canadian carriers? Is anyone else doing this?
I don't care for LTE, HSPA or HSPA+ is good enough for me.
Hey, if the phone is unlocked you should be able to use it with both Wind and Bell straight out of the box with no modifications and get HSPA+ connectivity.

T-mobile unlocked question

If I get the t-mobile unlocked version, can I use with AT&T sim? Would I get LTE, HSPA or just EDGE?

If you get sim unlocked you can use an AT&T sim. You will be able to get GSM, GRPS, EDGE, HSPA, HSPA+, but no LTE as the LTE radio is software disabled on T-Mobile Note 2's. I remember seeing one Guy claim he had it but I don't remember who or where. Once T-Mobile activates their LTE then you will get LTE on AT&T also.
You may need to add AT&T APNs to use data but they are easy to find/add.

Foxfi in verizon G4 with a different carrier or overseas?

Hi guys! I'm thinking about buying a g4 for my girlfriend and bring it to Mexico with me, I don't really care about root stuff but she does care about the wifi hotspot. I've read around here that foxfi app works for Verizon g4 even after the MM update .
So my question is if the Verizon G4 wifi hotspot with foxfi would work with a different carrier either in the us or overseas, has anyone tried to do that with a different carrier? Thank you!
Anyone ?
No it doesn't work. I have a Verizon LG G4 using a Telcel SIM card and data its ok (H+ or LTE), but the tethering is not active it keeps saying you need a verizon LTE SIM, even using Foxfi.
Me too, bad luck trying foxfi with Telcel sim.
