San Francisco, CA
Some numbers to think about
There are about 75M att wireless customers currently. If att spent the $39B on these existing customers, instead of buying tmobile, it turns out to be about $520 per customer.
So on a typical 2 year single line contract, $520 is about 25% of the contract.
Heck if att is going to offer a 25% discount to all existing or new customers, i think they will put sprint under, effectively doing what they want to do with this merger.
