Can't make calls

Hello, I closed my phone completely for about 3 days. When I went back to it, I was connected to the Wi-Fi, it says my plan is good till April 9th, today being March 31.

When dialing a number, it goes into calling Wi-fi…we never connects and says response time out…but on the other side, the receiver says he received a call…what’s going on?

I suggest working through the troubleshooting steps here:
