I've been with Sprint for 2 years and thought they were the best carrier, even convinced my wife and her 3 daughters to switch to Sprint from Verizon a little over a week ago.  So, we switched here and her 3 daughters over, and got them android phones like the one I got in November, which are not cheap. I got a letter in the mail yesterday that I have until April 11 to find another carrier. Sprint is dropping me from their network because I use roaming too much. Today I call customer service to find out what I can do to fix this.  They say there is nothing I can do and that it happens to truck drivers alot. Why didn't they tell me before I spent all that money on new phones. She told me according to the letter, they have been trying to contact me. I guess they missed me when I was adding 4 lines to my account and buying new phones, or when I bought my new phone in November,  guess I am unreachable.
They will take the 4 phones back and give me my money back on them since their in the 30 day window, but my phone and HTC EVO 4G may be bought back for $130. I won't know that until Monday when their "buy back" office is open. Now I'm scrambling trying to get another service provider. WOW! I'm on their loyal customer program, hate to see what they would do to me if I wasn't. 
I don't know but this sounds anti-truck driver to me. I guess some where in the fine print I missed the hole roaming thing. If you are with Sprint, be careful. They said they wouldn't charge me the $200 for early termination on all the 5 lines, guess I'm lucky.


On a cliff note, AT&T also does this. The only one I have yet to see drop a trucker from roaming is Verizon.
