I did this on my one plus 6 phone to try to enable wifi calling. Got that working but then now my phone will not call forward anymore. It now gives a network/sim card error. Had them change out my sim still doesn’t work. Put sim in my older one plus 3 and call forwarding works fine. Just no longer works with my 6. Only change was going into the logkit and enabling wifi calling. Any suggestion, I went back in and deselected it but that did not give me back call forwarding.
