hey i have a curve 8520 and at times its getting more frequent i get the message call failed or when i try to send a request to the network eg.*120# i get general service error:general error. i contacted my provider cst service and they told me that it might an issue with my phone. i dont think so cause whenever i try to select another network it does but when there network it says failed.
can anybody tell me whats happening here and if there is a way to solve this

thanx
