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.

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.
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.
As you know, all verizon lte phones are unlocked. So I inserted a att sim card to verizon g3, im not getting ANY signal. If you want to argue that verizon lg g3 is cdma only, go google it, its compatible for both gsm and cdma. anyways back to story, I tried changing apn, settings to lte/gsm/udtp, still nothing. I tried 3 different sims, verizon sims works fine but its at&t sims im having trouble with.
can GSM phone sim unlock be use with verizon or sprint? I stick my htc one m8 with a verizon sim, and it doesnt detect anything, I'm not sure if I did something wrong or the band just doesnt work all together.
Is it even possible? The phone has been unlocked by ATT but when I insert my verizon sim, it only lets you make emergency calls. I realize that the cdma bands wont work, but I assumed it would work on LTE. I definitely could be wrong though. Anyone know?
