Use a Verizon iPhone 4S on AT&T?

Parachute07 3,925 1,315 June 3, 2012 at 08:30 PM
Hello all,

Thanks in advanced for your expertise.

I picked up a good deal on a Verizon iPhone 4S from Cowboom with an eye to trading it locally for an AT&T iPhone 4S or reselling it for a small profit. As I was browsing my local Craigslist, I saw someone had an iPhone 4S listed as being a Verizon 4S but they could show you how to use it on AT&T or T-Mobile. I did a search on the Internet but couldn't find any reference of this being a possibility. Anybody know anything about this?

Simple. The iPhone 4S for Verizon and Sprint are global models, so they have a microSIM slot. all you have to do is unlock it, get the APNs for data, and you should be good to go.

Is there a way to unlock it without being a Verizon customer?

I want to use it on Straight Talk. It's for my girlfriend actually.

As I understand based on what I'm reading, Verizon will only unlock it for international use and only if you're a current customer with at least 60 days with them.

We are no longer Verizon customers. Is there another way to get it unlocked? It looks like most things I read online say that it still won't work with a US microSIM -- only an international one.

We have a Straight Talk microSIM already........using it in an iPhone 4 right now (and I have one in my Galaxy S II with a full-size adapter).

Thanks for the help!

If you get Verizon to unlock it, the SIM slot is still only unlocked for international sims.

About a month ago there was a workaround to unlock using SAM but that loophole is no longer working. I think the only other option you have currently is with a sim imposter such as

Just make sure your IOS version and baseband (modem firmware) is compatible.

It makes absolutely no sense buying a verizon version then having to go through unofficial unlocking methods and preventing you from updating the phone when new patches and features come out. Why on earth do you even consider it?? Is that worth the $10 that you will save?

Its just not worth $10 if thats the saving part.

The verizon/Sprint iPhone 4S are only already unlocked for GSM bands used outside of USA, the USA bands are locked and I've not heard of anyone getting those bands unlocked by the provider. It can only be a matter of time before both Verizon/Sprint have to start unlocking these after contract is over, just like what AT&T is having to do.

Thanks. I had seen those while doing some research on this. Like I said, I got the phone at a good price.......but not really good enough to justify spending an extra $60 on it. For that, I'm just going to sell the Verizon 4S unless I find someone willing to trade locally for an AT&T one. I'll take my small profit on this one and toss it towards an AT&T 4S. I didn't buy the Verizon one planning to try to use it on ST..........I was just intrigued after I saw someone on CL mention the possibility.

I'll just hold out for now. Thanks everyone!

Wait until at least Monday to see if new models are announced. That will help drive prices down and increase supply as people get rid of their older models in anticipation of the newest one.
