After searching for lot of forums for parsing incoming SMS from GSM modems, i ran out of options as no forum mentions how to parse the incoming SMS from GSM modems, I finally had a chance and was successful at parsing the incoming messages in proper format. Anyone who has trouble parsing the messages will find this these scripts helpful. Adding on, i have developed some functions for GSM modem for sending SMS, reading and Parsing SMS, Deleting, getting signal info, and sim card status. All are written in Bash shell scripting on Openwrt and tested with 3 modems i got a chance to work with : QUECTEL: EC-25E, HUAWEI: ME909s-821 and SIMCOM: SIM7100E.
Hi @p3rtinax , are you able to communicate to your Quectel EC-25E via openwrt terminal? are you able to send AT commands to it, are you sure the correct drivers are loaded? can you see the /dev/ttyUSB* ports getting created?

Hi,
Executing simStatus.sh give me this error: ` Checking SIM CARD status
UNABLE TO DETERMINE SIM STATUS`
running bash sendSMS.sh and nothing, just blinking cursor :(
I'm using the modem as my LTE connection via QMI right now, I don't know why your script can not communicate with EC25?
can you plz guide me?
