Hi!
My partner recently changed his SIM from Virgin to O2 and now I am unable to call him. When I try to call him, the call just drops and makes a beep sound. No ringing is made, and he does not receive a notification that I have tried to call. He can call me and I can answer, and we can both send text messages to one another. I don't have any problems with other contacts, and other Virgin SIM phones are able to call him with no problem at all.
We have checked that we haven't blocked each other, cleared our calling cache and data, and removed the contact and added it again.
Does anyone have any knowledge on why this is happening and how we can fix it please?
Thanks!
