I have a Moto E4 Plus.
I am on the $15 dollar a month plan (text and talk, no data except on wifi).
My plan just includes text and talk
I am out of the country at the moment and I have been calling home via wifi. I tried placing a call just a few moments ago and it said “Mobile Network not available for voice calls”.
I restarted my phone to see if that would help and even turned off/turned on mobile data. It still keeps saying “mobile network not available for voice calls” despite these attempts.
