hi ojenge,

osmocombb supports sms. you can also "sense" RF frequence, but you need 
to add some feature to do measurement at the first plane and then send 
the sms with the results. c123 is capable of receiving GSM downlink 
frequencies only. you may also receive uplink and even (with 
modifications to the firmware) receive frequencies a bit outside GSM 
bands. in this case you need to replace filters or your signal level is 
reduced. the osmocombb firmware is capable of measuring rx levels of 
given frequencies while being idle on a gsm cell. what do you want to 
"sense"?
