contacting at&t from abroad
I traveled abroad with 2 sims with a prepaid plan. I will not be in the US the coming months so I want to cancel them. I have no online access to do this as they are sending me my password to the the phone number and here I have no service to receive the message so I am not getting it. And my other phone can't call US to do this by phone.
how can I contact at&T to provide me with a password so I can access my account?! thank you!
