Sprint knows that if they ever dropped there unlimited data they would be out of business. Like I said it is the ONLY trump card they hold. I travel so much I don't think there is a single carrier out there that will be trouble free in all area's. SO for that fact I will stay with Sprint. However I am about to call up retentions, since my 3 lines are out of contract ,and threaten to move just to see if they will throw me a bone like they use to.
