My in-laws told me about Tmobile's promo to add another line on the family plan. I get unlimited data and pay $30/month. Even better, when we go overseas, I don't have to search for a local sim; the plan has (slow) international data.
I was paying about twice that to at&t. Since AT&T sent me a letter about the price increase on grandfathered, I was pissed.
When I called to cancel, they were trying to price match...too little too late.
How were they trying to price match? When I called and asked to speak to customer loyalty.. I got nothing.... in fact the CS told me that they could do nothing and I should switch carriers.
