I have a Sidekick 3 and for some reason it won't receive calls. I have a razr and it will receive calls every single time. I have the new FlexPay account because I hate signing contracts. It took everything I have in me to sign a contract with my cable company. Does that have anything to do with why my calls get sent to voicemail? I even turned off the data and talked to T-Mobile and it still won't work. I am also roaming too (for another 13 days) so I don't know if this has anything to do with it either. I'm having to have people send me texts so I can know they tried to call and call them back.
