T-Mobile has issues texting to Sprint here in the wilds of northern NJ as well. My daughter texted me at 2:45 PM yesterday and I got it almost a 1/2 hour later. Wifey-poo's AT&T phone texts get to me on Sprint instantaneously. This is why I'm migrating both kids' lines from TMO to Sprint next week. Contracts are up, theres money to be saved, and better coverage to be enjoyed.
