hi community,

i am using a n900 and i am very happy and satisfied to work with this device. i am a normal user with some linux skills.

since a few days i have the following error message on the screen:
"All telephony functions, including emergency calls, are disabled due to a communication error. To recover, you might have to reboot the device."

i am switching off and on the device. it is working for a few hours and then the error comes again. i am not sure if it is the sim card or the device itself.

are there logs or tools on the n900 to check what is going on?
if there are already threads for analysing such a problem i say sorry for the double post. i would be happy for a link.

best regards
