I have a Galaxy S9 and have been on Virgin Mobile since January this year. Until recently I've not have any problems with using the phone on the Virgin network.
However about 2-3 weeks ago I had problems make a call to someone and they had the same issue calling me back, which was that the message "Conditional call forwarding active" would appear (not noticed this previously at any time) and the call would not connect. The calling app would simple drop the call attempt after a couple of seconds. After numerous attempts, one of us managed to get a call through to the other.
This wasn't a case of both of us attempting to call each other at the same time, as we were coordinating our call attempts over Whatsapp.
The problem went away until yesterday, when I tried to call my doctor, which took 3 attempts, as the "Conditional call forwarding active" message and dropping the call immediately behavior was back.
Later in the day I had the same issues again, when calling, or recieving a call with the person I first experienced the issue with.
I tried to disable the various Call Forwarding options in the phone's settings, but got this message.
"Failed to read data.
Something went wrong. Check your SIM card or network connection, then try again."
I have since removed and reinserted the SIM card, as well as restarting the phone. The issues seems to be limited to making/receiving calls, as the data connection works fine and the network strength is shown as 4 out of 5 bars.
I've also gone through the process to get the phone to automatically find the mobile network and connect to it (Connections/Mobile Networks/Network Operators/Select Automatically), however I'm still experincing most calls failing to connect and the Call Forwarding message popping up.
Any suggestions would be appreciated.
