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.

I know that a few years ago that it wouldnt work. Just seeing if anything has changed. I have the unlock code for my att tilt, but I am now on verizon. I hate my phone on verizon. And I am trying to figure out how to use my tilt. Any and all help would be greatly appreciated.
I'm not sure the exact difference, but I believe that due to Verizon being a CDMA network and AT&T being a GSM network, you can't use a device from one network on the other.
If I'm not mistaken, AT&T and T-Mobile unlocked phones are compatible, and Verizon and Sprint unlocked phones are compatible. That is to say, an unlocked AT&T phone will work with T-Mobile (and vice versa) but not with Verizon/Sprint.
im really lost in the terminology behind all of the different phone standards... umts/hspa/gsm/evdo/1xrtt/lte/wimax/etc etc etc...
Verizon (and Sprint) are CDMA dominant networks. But Verizon LTE requires a SIM-card:
(1) Will a Verizon LTE phone accept a GSM SIM and work at optimal speed? e.g. Vodafone SIM in UK
(2) Conversely, can't the "Global/GSM" Galaxy Nexus take the Verizon LTE SIM and work on Verizon's network?
(3) Is the Verizon LTE's version of Galaxy Nexus a hybrid CDMA-GSM phone (like Sprint's Photon) ... i.e. if I get it unlocked, I could also use it with most international services?
The unlocked global GN is 750$. But if Verizon's contract price is 300+200 [term. fee]... AND it works internationally... clearly its the way to go
1 - No.
2 - No.
3 - No.
You're confusing SIMs for radios. Each phone has a different radio that can connect to EITHER GSM (UK model) or CDMA (USA model). The GNex cannot connect to both.
The GSM version will work in the US with a T-Mobile or AT&T SIM card on a GSM network. You can also take it on international trips (changing SIMs or roaming), as most of the world uses GSM.
The CDMA (Verizon LTE) version will work on Verizon only.
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?).
Hello, It is my understanding that Verizon phones are unlocked. have an HTC One phone that I would like to switch from Verizon to ATT. When I put a new sim card in the phone, it seems the ATT network is being blocked. Any thoughts?
Correct me if I'm wrong, but Verizon uses CDMA and AT&T uses GSM. The only way you'd be able to switch to AT&T with an unlocked phone if it was under T-Mobile.
Title says it all... I was wondering if its possible to get it to work
Unfortunately, no, it will not. AT&T is a GSM based carrier and Sprint is a CDMA carrier. The two technologies are not compatiable at all.
Source: Recently asked the people at the AT&T store this very question.
Yes AT&T will work up to HSDPA on the sprint galaxy s6 as only the LTE bands are different, do a search for unlocking sprint Galaxy S6 by I one or give me a DM.
Yes it does work if its unlocked domestically
