AT+CREG and some other AT commands like AT#Moni has a very long time out (up to 180 seconds). I could not recommend to use AT+CREG to often, because then the GSM module is busy with handling this AT command and will not be able to do the main job like sending or receicing of SMS. You can train the GSM module to give you the extented error messages. Based on this error code you will know what is going on. BTW, GPRS modules on good price level and best support by biggest user group for for GPRS modules you will get at

You can meet the team of Round Solutions twice a year in Italy and . The speaking "Making mobile devices like playing with toys" is listed at: . Next event in Italy will be the M2MForum in Milano (April 2008) Regards Meff
