@iraahmed you had your service working perfectly before (incoming and outgoing calls and text and mobile data), then you go to Change Number to change a new number and cannot make any outgoing calls?
or you meant you port into your number from another providers and have problem?
If it is the first situation, I guess you already rebooted the phone many time. Do you have another phone to test putting your PM SIM into there and test?
If still fails, open ticket with PM Support :

**Monitor your Community inbox (envelope icon on the top right) after the ticket is opened. CS Agent will reply you there
If it is a porting issue, then you should have incoming calls problems and not outgoing
