Gevey Sim with Iphone outside the U.S.? maybe you are having the same problem. Read on.
(Or skip to end to see how to fix it)
Under no circumstances I will take credit for any of the solutions listed bellow. I’m simply posting here a sum-up of the steps as my dad in Venezuela described them to me. If this little tutorial works for you, then the credit goes to every iPhone enthusiast out there and of course, my father for putting things together. I hope this will fix your problem of not being able to see the name of the person who calls but just the number when using the Gevey Sim to unlock your iPhone. Also, once you fix the issue with displaying the names, there was another issue: The recent calls list would not show the names, but the numbers only of recent calls. All of these things, of course, would be because of the use of Gevey Sim to unlock.
However, once you resolve this issue and your caller ID begins to show the name of the person calling you, then you have now inherited another problem: The “recent calls” list would not show the names using Gevey SIM, but the numbers only. This is because of the fix above. If you don’t fix the problem above, then it would be reversed. But, you want both the caller ID and the recent calls working properly, right? To fix this, you would need to do the following: At this point, your iPhone needs to be jailbroken and have Cydia installed.
Now it all should be working just fine. The reason for these steps above is because the Gevey SIM interposer is not related to any country and it uses a default country code as 001. That’s why you need to assign the country manually to fix the called ID issue and the recent calls issue. I hope it works for you.
