I have problem with my SIM card for two days. I have no signal, I cannot access my mobile data or call anybody or send SMS. 

I already tried restarting phone, manually choosing operator and putting mz SIM into another device. Nothing seems to help.

Hello @Kotarra,

welcome to our o2 Community 😊

I am very sorry that you are having trouble with your SIM card at the moment. I have checked your adress in our Live-Check. At the moment there may be restrictions due to maintenance work on our mobile radio stations in your area. The maintenance work is scheduled to end tomorrow evening, so I assume that you will then be able to use everything as usual again.

Please let us know if you have any further questions.

Best regards

Giulia
