Won't work. AT&T is not stupid. It might work for one billing period, and then try calling back with another story.
True that, ive tried all the tricks in the book when i was living in an area with no 3G. They... are a smart company. I was on the phone for a good 6 hours with some lady who i think was a lady but couldnt tell over her incredible middle eastern accent.
funny thing is, AT&T sent me a letter a week later telling me they were terminating my contract, that they would pay the 200$ ETF because i wasnt in actual AT&T coverage i was just in a partner area and supposedly "used too much data".
But here i am again with AT&T.. weird
