Not able to make phone calls, or receive phone calls

[dagmardur]

When I dial a number, there is not dial tone, but it says "calling" and I don't get to connect. When I friend called me to test the connection, he said he got my voice mail right away, nor ringing. I am on 4G LTE. 3G is down and I can't connect to it.

@dagmardur  Try to reboot the phone if you haven’t already , or reset network settings . Can you try the sim in another phone ? And did you just join PM and try to port number over ?
