I presume you mean that you cannot make or receive calls?
To/from any mobile and landline number?
Or just specific numbers?
Did outgoing/incoming calls ever work for you?
If so when did they stop working?
Did anything change before this happened? E.g. software update, settings changes etc.?
Can you send/receive texts?
Do you have a network signal/connection?
Do you have an active membership?
Log into your online account or the app to check your current membership status and expiry date.
Do you have any mobile/landline call allowances left?
Handy short-codes
Hope this helps.
