iPhone 4S AT&T | Phone/Device Issues and Features | Consumer forum

gevey or r-sim 3 should work. i used one on my telus locked 4s before.

however, the new so call auto unlock(i.e. it dials 112 for you) has it own issue. In that at times, it would fail to unlock and needs a bit of stunt to re-do it(needs to carry the small pin all the time).

I would suggest to pay att and get it unlocked.

iphone 4 and the gevey ultra(manual 112) is actually easier as it works every time i have tried.

I know how to unlock it but I'd like to know if it will work without unlocking it. I haven't bought it yet so I'm inquiring beforehand.

it won't work without unlocked your iphone 4s. You can unlock free from AT&T if you are under contract with them

or you can buy unlock on ebay very cheap

that's still the gevey site. What he was referring to, I think, was AT&T permanent unlock available from sellers on a certain auction site.

If it has to be AT&T, those are your options. Get a Rogers locked one to avoid all this. Or of course a factory unlocked one.

proper unlock is ~50 be it ATT or Telus/Rogers.

R-SIM 3 is very cheap like 5-10 bucks but has the mentioned issue.

It works, just very annoying, much more so than iphone 4 + gevey.

oh no get factory unlock on ebay for AT&T I saw lowest $10

Don't buy gevey sim

Just look for vendor ebay and submit your imie number and wait about 6 hours then your iphone AT&T will unlock
