I've been having an issue with my phone randomly making me restart my phone to check for a SIM card when I have one inside. I've tried new SIMs and I also sent it in to Samsung to get repaired. They put in a new SIM slot, but I keep having the same issue. Help?

Here is what I posted on the AT&T forums. I am just trying to get my phone re unlocked

I just received my Galaxy S4 back from repair the third time and now it is carrier locked. The original problem was it from kept losing the SIM card and having to reboot the final repair Samsung replace the system board.

I originally had this phone unlocked as soon as I bought the phone. Now after I got it back it is carrier locked and the unlock code does not work.

I got the phone back from Samsung with the same serial # and IMEI # so the original unlock code should work however it is not.

Samsung says to talk to AT&T but AT&T is giving the same unlock code.

From what I have read when a system board is replaced your serial and IMEI should change too, however mine did not.

I have found that Samsung has documented the actual IMEI of the new board is different then what is programmed into the phone. I wonder if I can get an unlock for the actual IMEI. I do not have the serial number just the IMEI of the board they put into the phone.

Well seems ATT will not unlock the phone becasue the hardware IMEI seems to be in the system as another AT&T customer. They may be sending me a new phone and they want this one back to see what Samsung has done. I just want the phone unlocked.

Should I just buy an unlock code with the IMEI that samsung said the IMEI is of the system board?

This is really getting annoing.

No because it will do the same exact thing and Congress just passed a law that states they have to unlock it upon request I'm gonna see if I can pull up the article

Well just got all this taken care of. Someone in AT&T development got a hold of me and they sent me a new phone and what the one Samsung repaired for testing. Apparently the system board Samsung used in my phone was another AT&T customer and was causing issues on the network having tow of the same IMEI reporting on the network.

I now have an newly unlocked S4 and have to send the one Samsung repaired to a department in Washington state.

I hope this phone doesn't have any issues because I am tired of all this mess.

Oh my glad you were able to see what I meant. I did not proof read what I typed in Tapatalk. Hope this is not that wide spread of an issue. I now have a new phone and no issues.
