This happened to my old I60. Try turning the phone off & then back on, this fixed mine. Also, the tech suggested taking an eraser & cleaning the battery terminals in the phone & bending them out a wee bit. Hope this helps.
either a soft reset by turning the phone off and taking the battery out then turning back on...or you can do a master reset and that should take care of it. u can call nextel tho and have them troubleshoot it...perhaps the tuning resources are off!
naa ur wrong if nextel shuts your phone off or suspends your accoutn you will beable to do NOTHING accept pay your bill to a representative ... yes sometimes they get errors but motly this problem has todo with your past do payment
