Canceling autopay from outside US
At first I bought sim card for one month and after one month I prolonged the plan and set the autopay on because it was cheaper than not doing it. Now I’m back in my home country and which means I’m currently not in US. I tried to cancel my plan via “my at&t” but my access was denied. I think it is because I’m at outside US. Anyway, how do i cancel my plan before automatically paying for next month? Actually I searched for information and it says i can directly make a call to international support number but I don’t know if it’s free to call foreign number. I really need help!!!
