have data, text but cant make calls.
Long story short, got this phone used 2 weeks ago, unlocked it on fusion unlock and its been working perfectly since day one, however, today i cant make calls, when i use the dialer it sends me to a black screen and then back to contacts, no error mesages or anything,
I have data, can send texts, but no calls, phone works perfectly fine, im on Telcel America.
Any idea on what could be the problem? i -though it could be related to some wifi calling setting but i cant find it anywhere.
