Ok...first, it's not a carrier issue because my girlfried is using the same carrier and has no problems. Second the signal strength is "-75 dBm 19 asu", but like I said, the signal appears to be full when the phone conversation is stating to have problems and I'm not walking when I'm on the phone ( the signal can not be lost by changing the place from where the phone is used )...I have 3 or 4 bars all the time...so I don't think it's a hardware problem because if it were I shouldn't be able to have good signal at all, but I do. That problem doesn't always appear.
I know that I should change the modem but I don't want to decrease the battery life. So, my questions are:
1. If I change the modem will the battery life be affected? If yes, what is the best modem for battery lifetime? If no, it is deppending on kernel:
2. Are there compatibility issues between modems and kernels?
