I tried flashing Cyanogenmod 10.2 on my SGS4 Mini I9192. It all works fine, nice UI, wifi connections, everything. The only thing that doesn't work, probably the most important right now, is my mobile network. The phone prompts that there is no sim card inserted, which there is. I can't call, send/receive texts, or use mobile data.
If anyone has a solution to this would you kindly explain this to me. I am not the most tech savvy but I know a enough to flash roms and root.
