Thanks for your excellent app. Ok, my problem is: I have 3 cellphones: my great n900, my mother's cellphone and my father's cellphone. So i decided to check the great feature of receiving the new sim number (when i change the sim card). I set my mother number in the smscon-editor and all the test work fine. I type smscon -imsi and i see 1 imsi number (mine). Then i change the sim card (i put my father's sim) to check that great feature. But i don't receive my father's number via sms to my mother's cellphone. I type again smscon -imsi and now i see 2 imsi numbers. I type smscon -log and i see: DAEMON INFO: reading 1 IMSI codes from "smscon_code" file DAEMON WARNING: IMSI code has changed to "xxxxxxxxxx" DAEMON INFO: added IMSI code (xxxxxxxxxx) to "smscon_code" file (the Xs are numbers) It should send the new number, not add the IMSI code. thanks in advance for you help.
