I activated my new prepaid simcard last Friday and converted it into an esim on my iphone. Internet is working fine, and I also receive sms.
Today I tried to make a phone call, and to my surprise every number I call I get a busy line. I tried to call my girlfriend whose phone was there, not on a call, and still got the line busy.
I deactivated Volte and the problem persists. I tried via wifi calling too, the problem persists.
The customer service is hard to reach via phone. How can I be assisted?
