I had Sprint at one time. Got rid of them as soon as the contract was up. Always had dropped calls, no service where they said we SHOULD have service and very bad customer service. Switched to AT&T. Loved them. Sure, had a couple people with Customer Service that were not very nice, but another call into then and speaking with a supervisor got things moving. I would get a couple dropped calls, but always got reimbursed for it. Never had a problem.
Here on the pebble, I cannot wait to get rid of the cell phone people I have. Bunch of liars who do not honor their contracts and have even gotten lawyers involved.
When we get back to the states, I'll probably go to a Pay As You Go plan because I very seldom use my cellphone. It's for emergencies and quick calls only. I don't text and people who know me KNOW I won't text them back and have a conversation with them. You want to talk to me, then CALL! lol
