I will soon have a situation and was wondering if folks here could shed some light on it.
My wife owns an AT&T mobile phone. This weekend she'll get a T-Mobile phone at LAX before she flies to Australia with Oprah Winfrey. Her existing number is and her new number will be +1-512 numbers. I'm considering forwarding her AT&T phone to her T-Mobile phone so she can receive calls at her known, existing number while in Australia. My question is which phone will take the hit on the bill? The AT&T or T-Mobile phone? Her AT&T phone will be turned off and will remain off her entire trip abroad.
