how to know if my iphone has been unlock?

Thanks for the info! I've used your recommended site too. 🙂

The sites posted by seanachai51 appear to check the registry out there rather than the actual state of your phone.

I just requested an unlock from AT&T and got an acknowledgement, but haven't actually gone through the restore process, and iphoneimei.info says my phone is unlocked.

It would appear, then, that using another SIM is the only sure-fire way to know if the unlock actually succeeded (that and the "congratulations" message, maybe).

Just adding that the presence of the settings option, Cellular Data Network, found at...

Settings>General>Cellular>Cellular Data Network

would seem to be conclusive proof that a phone is unlocked (from AT&T at least), but this option did not appear while my AT&T sim card was still in the phone. So the iphoneimei.info site looks like the only resort if you don't yet have another sim card to put in.

Once the phone is unlocked, I did see that the option reappears, after swapping sim cards, without restarting the phone.

The most useful tip - Must try this way - thanks a lot NemeinWulf

HELP!!!

I just purchased an iPhone 4S to take overseas and use with a foreign SIM card. I purchased from someone who unlocked it at contract expiration, which seems to be the case because every website I've checked lists the phone as unlocked.

When I put a friend's Verizon SIM card into this phone (which I presume isn't a Verizon iPhone), I am not receiving any telephone signal (all calls just fail). Can someone just verify for sanity that a Verizon SIM will not work because it is CDMA while basically everyone else is on GSM? I probably need to find a T-Mobile or AT&T card to test this. Darn....

Thanks....

Yeah, if your unlocked phone is GSM, the only way to know for sure is with a T-mobile SIM (or some other lesser-known SIM -- like from outside the US). Verizon won't work because it's CDMA, and AT&T would work if the phone were still locked. I was lucky to find a friend with a T-mobile SIM to try.

Hello

Thank You for sharing the links to check your IMEI# I used the http://iphoneimei.info/ link

It came up and said:

Activated: Yes

Last Activated Sim: AT&T

Carrier: Unlock

Sim Lock: Unlocked

I know in one of the messages above if it says Sim Lock: Unlocked means your phone is unlocked I was looking to buy this used AT&T Iphone 4S to replace the Sprint Iphone 4S that I have that Sprint will not unlock for domestic use even though my contract is up.

This is the status on my Iphone 4s using: iphoneimei.info

Activated: Yes

Last Activated SIM: Sprint - United States US

Telephone Technical Support: Expired

Repairs & Service Coverage: Expired

Carrier: US Sprint

SIM Lock: Locked

This information is correct. I decided to do it on the AT&T Iphone I want to buy and it says

Activated: Yes

Last Activated SIM: AT&T - United States USA

Telephone Technical Support: Expired

Repairs & Service Coverage: Expired

Carrier: Unlock

SIM Lock: Unlocked

I checked the other site: http://iphoneox.com/ for the AT&T Iphone 4S I want to buy and it says:

This site shows something totally different which i know is wrong. Which site do I believe. My phone status for this site is:

Since this is my phone I no its a Sprint Phone and its locked even though its out of contract. I didnt use the other site S-urlo.ro as it was paid. Before I spend the money i just want to make sure the sites are accurate. I do not assume things. The iPhoneIMEI.info looks like the more accurate site and several people in this forum use it.

What do you all say. Do you all think the AT&T Iphone 4S is unlocked. Just curious what does it mean on the iphoneIMEI.info site when it says:

Activated: Yes

Carrier: Unlock

Thank You for your time and help

The only reliable way to find out a phone's lock status is to call Apple Care and ask them.

I unlocked my 5s and received a confirmation message on my iTunes interface stating phone had been unlocked

The report has one mistake - my iphone ios firmware is 7.1.

ALL IMEI checkers are scams. It's no surprise that there are mistakes in their "report". Note that all of the information you have posted is directly from the specs for the phone. There is nothing in that ersatz report that could not be determined from the model number alone.

@Lawrence Finch I agree with you. Almost site is using the GSX info, and it's is updating by apple. They can not keep update their database so that make some info is incorrect. But you can use their tool to check some helpful info before buy, sell or looking phone info. In my option i choose https://imeidata.net to check this info.

Forcheck simlock, activation status, find my iphone, model, color, storage, carrier and for model, factory, manufacturer date, order code, country, sold to.

Furthermore, one good thing site can do is check replaced device, I was use it to check some iphone replaced by apple center then they change to new IMEI, new serial number, that site give both original and replaced serial number. It might help you.

Dude thanks a ton, That really worked!!

thats it, really worked ! thanks !

Well that is pretty cool! More than 3 years later my comment was officially recommended by Apple. :-)
