Call Failed

[KellyB9]

Hi,

I am unable to make any calls. iPhone constantly saying “call failed”

I have good service and WiFi. 
Had a cellular iwatch linked to my account yesterday and wondered if that is the problem. 
Can anyone help please?

Thanks

p.s I have turned it off and on, reset network settings and messed with the aeroplane button

Rather than posting on a 3 year old thread, it would be better if you created a new thread. 

Also as this is not Customer Services but a customer to customer community, the best option is to reach out to o2 all the contact details are here Guide: How to find help & contact O2 

It may also be worth checking https://status.o2.co.uk and these guides

Guide: How can I sort out my network issues? 

Guide: Is the network down for me or everyone?
