My last experience with t2 support is over a year old, but then it was lousy. I had a fatal hardware failure and needed to move everything over. I was on hold for at least 1-2 HOURS before I got a semi-cohernt tech. This was typical with (virtually) every other call I made to them, except on those rare occasions.
My (former) mgmt looked into other alternatives, but nothing was ever purchased.. If I could have called the carrier (then Nextel) and got immediate support, I would have done it in a heartbeat.
