Hi, did you manage to find a solution for this problem as I have been unable to resolve a similar issue. My sim error appeared randomly on the latest unrooted stock btu build. I have even replaced the sim reader. Any suggestions would be appreciated.

Thanks.

greetings
i had the same issue, quite frustrating.
I bought my Note2 with broken Display, after i repaired it cut my sim to a mico sim, tried it out and got "No Network". So i replaced my 2 Years old Sim with a new micro-sim and with no luck.
After some error diagnostics i found out that the IMEI was broken, well f**. One month later is repaired the IMEI at some Mobile Service-center and the guy demonstrated that the phone now works. Well ok, i was. At Home i inserted my Sim and it didn't worked. I tried my brother Sim cards (2 old Drei Crads) and they worked, now i was like WTF.

Tested Sim-Cards (all Sim mentioned below are from Austrian Carriers)
T-Moblie (2Years old) => ok
A1 (2Yeas old) => ok
3x 3AT (old Sim Design before 2014) => ok
neu 3AT Sim Card since 2014 => NG
I already replaced the sim but with no luck since my carrier gave me the same new Sim Design.

Today i found the issue, the IC or contacts of the new sim are a little bit dipper molded in the plastic. I put a small piece of paper on top of the sim, so the sim is forced down on the simslot contacts, so far i had no issues. I will report this to my carrier and see what thy gonna say.
Hope dat helps, cheers.
