Unable to make an international call with PREPAID phone
My wife has a Samsung Galaxy S9 on a grandfathered PREPAID 10c/minute plan. She's always been able to make international calls before. But today she tried calling a number in Ukraine and keeps getting "unable to complete the call" no matter how she tries to dial it. We put more money on her account, just in case, but it didn't help.
I tried calling the same number using my iPhone XR on a Mint Mobile plan, and it went through, so it seems to be an AT&T issue.
Has anyone experienced anything like that?
