Hi, first of all i have a old Nokia 6230i and today it has no signal. A few things to make clear are that it is not blocked and i have also tried different sim cards, but still no luck. The stange thing is when i switch on the GPRS, i get signal from my network operator, but when i try to make a call its says error in connection. When i turn off the GPRS i have no signal and still can't make calls. So guys? how do i fix it, so i can recieve signal and make calls and texts, please any ideas would help me?
