Sprint just did it again and doubled their data buckets after ATT matched pricing last weekend.
So for the $150 I'm now paying ATT to get 40GB Sprint will give me 80GB.
Plus no device access fees until 2016 (would save me another $60/mo.)
Sprint's offer is pretty compelling. I'm almost ready to make the switch since their coverage is just as strong and comprehensive as ATT where I live. But if ATT could match I'd definitely stay put.
