Just turned my sidekick on and i got a "Please insert Simcard" The sim card is in so i took it out and put it back in and it restarted. I get full bars on restart then try and go on the web. works for 1 min then looses signal again. this happend out of no where anyone know anything i could do? I have tried everything (hard reset,battery,all resets,flash,everything) I also get a no wireless services message i think it was a net7 message?
