Replicant

Hello,

I have a Galaxy S3 running Replicant and been using it without sim card for over a month now. I'm glad that there exists a mobile operating system that takes freedom seriously. Today, I got a new sim card and tried it on that phone only to find out that it didn't detect the card. I tried it on two feature phones, one of them detected the sim card but then said SIM CRASH, the other detected the sim card but says that I can only do emergency calls. I also tried it on someone else's fairly modern smartphone and it worked, but not on the other phones. I tried inserting my old sim card into my Galaxy S3 and it also didn't detect the card whereas one of the flipphone detected the card so I suppose that Galaxy S3's EFS partition got corrupted? Does the sim card only work on modern cellphones? I think I have more than one problems, one is that the sim card might only work on modern phone and the second is that the EFS partition got corrupted. When I first installed Replicant, I made an EFS backup and now I did the backup again and I compared those two backups and they happen to be different. I also compared the new and old nv_data.bin and they are the same.

Is there anything what I can do to fix this problem?
