It's not possible. Verizon uses CDMA, EVDO and LTE. AT&T uses GSM and UMTS. Completely different technologies. However, if you can get an XT910, a GSM version of the RAZR, you can use it on AT&T (this is what I have).

im actually looking into this because my cousin has just left Verizon for att and it is possible they use sim cards and people have reported it working im not sure on many details of it yet but its out there just google "verizon droid razr on at&t"
look here http://blog.laptopmag.com/ics-world-phone-capabilities-come-to-verizons-droid-razr-and-razr-maxx
You cannot do that after the ICS update. With ICS, you can roam onto global GSM networks but many people have reported that you cannot change the default network from Verizon.
From everything I've heard the xt912 has the appropriate radios to connect with at&t cell towers but the usage of this feature is being blocked by vzw. Now I don't know if a custom rom like cm9 would allow for this or not.

RAZR on AT&T network
Yes it is possible. I did it. The only thing is that I only use the phone for calls and texts and WiFi for data. In the bionic forum, they tell you to download Radiocomm. I did not do that. AlI did was just change the setting to gsm/utms network and placed the AT&T sim card and waited for 15-30 minutes for the phone to connect
Btw, I'm on ics.

Dont worry, your English is better than a lot of people who actually live here! Ive heard rumors that yes both radio's are present, but no one has been able to activate the GSM radio in a Verizon RAZR.
Thanks for answer .. on eBay i see that, there sells unlock for GSM for Roger's droid Razr. But i don't see Verizon unlock))
Sent from my DROIDX using xda premium
Don't live in US so not shure but aren't Roger's using GSM?
I thought it were just Verizon who used CDMA.
Just got the XT912 a few days ago, from the packaging somehow it seems they use the SIM card for the 4G data package, and that sim can swapped between 4G devices, but the main part of the vzw service is still cdma.

***UPDATE 6/26/2012***
Ok, not all the info that I got before was 100% correct. It looks like RAZR / MAXX is unlocked only for Global(GSM) use which is outside of USA. The Tmobile and ATT sims are not fully working as of right now.
We have couple amazing Devs which are working to resolve this issue.
Please PM me if you want me to update the OP.

Actually the Bionic does have a GSM radio.
The Razr, 4, Bionic all have the same Qualcomm global radio and a separate LTE radio.
The only thing preventing the Razr, Droid 4 or Bionic from connecting to GSM is the firmware.
The Droid 4 is scheduled for GSM upgrade.

I was under the impression that we just needed the unlock code. Once we have it from say...att, then we put the sim in,enter the code and good to go...maybe its not that easy but on YouTube it looks pretty close lol.
As far as I know it's not that easy due to the fact that the GSM modem itself is disabled. Unless your talking about roaming onto the LTE network. Though ATT uses different frequencies.

Thank you I will follow it later on.
this could get interesting
Okay so, here's my predicament..I'm currently using an Atrix 2 with a regular sized SIM card and wanted to test this out on a busted VZW Razr I got from work (there's a huge crack in the screen and it was just collecting dust). If I went into an AT&T store and bought a micro-SIM, would it work?
The only reason I'm confused is because all I know that AT&T uses the micro-SIMs for is the iPad; I don't know if the structure of the SIM card changes to accomodate just data, or if voice will be able to be transmitted as well.
Att SIM card works on Verizon RAZR! Just needs little modification. Does not even require root! Thanks to the bionic forum

does data work ?
what "little modification" are we talking about
write up ? link ?
The procedure...
Data does work because I get an "H". But i choose to turn off data because i do not want to be billed.
I am on ics.
This is what I did (modified from the bionic forum)
- got an att sim card activated with a basic gsm phone
- turned off razr
- replaced the Verizon sim card with att Sim card
- turned on phone. You will get an "unknown sim card" error. Press ok
- go to system setting>more> mobile networks> select GSM/UMTS
- click back button, select access point names, select AT&T US (wap.cingular)
- press *#*#4636#*#*
- go to phone information, select WCDMA preferred, below it, turn off radio then turn it back on, exit by pressing home
- turn off data sync in the mobile data networks. Also turn off wifi.
- wait up to 30 minutes or more to let the phone connect to the network

I turned on data then I lost the signal. It would not come back even though the phone reads the access point name. I think either AT&T or Verizon saw that I'm using an unauthorized sim card and disabled the signal.

That's what I figured. Cellzealot is working on a hack but it doesn't look very promising - http://forum.xda-developers.com/showthread.php?t=1619563. They do have a hack for the Bionic to use 3G on AT&T. I set my little bros phone up a few weeks ago. Unfortunately, the hack seems to only work on GB and not ICS. Most Moto global phones can be unlocked for AT&T but since the Razr wasn't officially released as a global phone and they basically only announced global support because they couldn't patch it on ICS (my opinion, not confirmed), the Razr is different.

I haven't followed it as closely as I once did, but the Droid 3 is completely hackable because AT&T has a similar device. So I purchased the unlock code, flashed the GSM radio and it was done. TBH created a hack for the Droid Pro that would unlock it (old file, not recently updated) similar to the unlock file that works for the Bionic. They also have a Razr unlock file that I believe changes some settings to GSM (I don't believe it's a true hack just setting changes) but it doesn't unlock data in the US. It only allows data overseas. One user in the thread I linked to reported picking up data in the US but only because he's close to Canada and AT&T was roaming to Canadian towers. That's further proof that Verizon and US GSM networks have enabled some sort of block that is yet to be cracked. Cellzealot is a pretty smart guy. If I had to guess (that is IF it can be hacked), he'll be the guy to do it.
A general consensus across the board is that ICS has changed the radio handling which has made sim unlocking much more difficult and patched previous hacks. Again, I'm just paraphrasing what I've read from Cellzealot. He's your guy for more information.

Hi,
A quick question, would the HTC Droid DNA work on a GSM signal network such as O2 - UK? I just want to know if I would be able to send/recieve texts and calls. Also what internet speed would I get? would I get 2G/3G/HSPDA or none?
I have searched around and many sources say stuff about using it on ATT GSM network and when I live chatted with Verizon they said specifically CDMA network only.
Thank you
Taylor_Swift
Whoever you talked to is wrong about it being cdma only. It's a global phone, and as such has gsm bands and is SIM unlocked.
What bands does o2 use, that determine what data works.

Get VZ to send you a new sim card. The sim card is where the 4g lte is at. I had this issue about a year ago. VZ sent me new sim but that did not help although it does majority of the time.

I had a similar experience/issue on my phone a few months ago. In my case, I wasn't able to use 3G or 4G LTE. It took more than just a factory reset to get my phone back up and running again. What resolved it was Matt's Utility. Depending on which option you select within his utility, there is one (possibly more) option that not only wipes all system and used data, it also flashes the stock radios as well. I feel your pain buddy. Let know if I can help.
