Sony Xperia Z5 compact

Hello everybody!

I have an Sony Xperia Z5 Compact and from a few days it doesn't recognize the Sim anymore. The error is: "Sim is not allowed MM #3"

I checked the Sim card on another phone and it works. I reset my phone but still doesn't work. Any tips,advice? 😇

Or should I watch for another phone? 😪

Thanks

Have you tested a different SIM card with your device?
