Re: Fwd: Cellphone can't detect sim card

From that it is impossible to say what your problem is. Use an oscilloscope or logic analyzer to investigate various points on the PCB. Use debugging statements inside the firmware to investigate what is going on in the firmware. Provide the mailing list with detailed information about what actually goes wrong. You have to do that investigation yourself. Only then can you actually get some help. //Peter
