Sim card not working

[Yuli]

Hello, I wonder if anyone can help,my sim card has suddenly stopped working, I cant make calls or recieve messages, I can access internet and what's app through my home wi fi, I have tried switching my phone off and taking the sim out but it keeps showing no sim, emergency calls only and if I try to make a call it says not registered on network, though I have been with 02 for years and had the same number.
Thank you for taking to time to read

Check help here Guide: Is the network down for me or everyone? 

If it's a faulty sim, you will need to call customer service for a replacement Guide: Coronavirus Community Help and Support The best number to call on appears to be 0800 587 4005

Also check your MyO2 to ensure your bills are paid.

Thank you for replying, I have contacted 02 as the network is fine and my bill is paid they are going to send me a new sim card to try

Hope that sorts it for you.

*UPDATE I received my new sim card today, had to contacted 02 on a family members phone as I could not activate it from phone as could not text or phone, 02 have activated it and it is now back up and running.
I guess my old sim decided it did not want to work anymore.
Thank you

Yes, they do fail occasionally.

Glad you're sorted.
