Since this morning all attempts at making or receiving calls just tell me it FAILED. I have signal for emails etc. and internet connection. Just no phone calls.

I'm just going round and round with queries online - can't seem to connect to the expert.

Any suggestions for the technically illiterate would be much appreciated. Thanks

@Sonja1 

Check guide to narrow down the fault Guide: Is the network down for me or everyone? 

Using wifi calling may help in the interim.

Hello, thanks for your response. I've followed the suggestions, but I'm still stuck. 

I have signal, wi-fi calls enabled, mobile data enabled.

I can use the internet, get new emails, etc.

The only thing I can do is make or receive telephone calls.

Are there any other suggestions? If not, I'll have to go into town tomorrow to an O2 shop.

Thanks.

Did you check for network issues @Sonja1 

O2 Service Status

Also make sure you haven't enabled airplane mode by accident.

Thanks MI5.

I've checked service status, which is fine, and airplane mode is off. Still can't make or receive calls.

I appreciate your input. Thank you.

@Sonja1 

Are you on contract or PAYG?

Have you checked bill has been paid or if you have an active bundle / credit?

I've now had a chance to go to an O2 shop in town. They removed the sim, cleaned it on a cloth, put it back in, and hey presto, it worked! Thanks you for your help - I really appreciate it.

Great news, @Sonja1 - SIM cleaning, yes important enough to be included in the guide listed in the first reply above, as here:

Chances are this was resolved by the IMSI disconnect/reattach. If the SIM contacts were dirty, this would have caused other authentication issues.
