Re: Since February I have not received a service for phone calls on my mobile phone. Sort it out ...
Welcome to the community
Sorry to hear you cant make phone calls on your mobile phone.
I presume the phone is in working order and you've taken the SIM out and placed it back in the phone again. Assuming this has been done you could also try a different SIM. If this works it would indicate the SIM has become faulty and needs replacing.
