Hi Mohammad,
1. Can you check your SIM and see if it is inserted in ?
2. You can also telnet into the iSMS device on port 5000 and type in:
AT+CPIN? <–Check to see if the SIM is inserted correctly. If it is then you should get a +CPIN:Ready.
AT+CSQ <–Check the signal quality
AT+CREG? <–Check to see if it is registering to home or roam.
AT+CMGF=1 <–Turn on text mode.
AT+CMGS=”your_cell_number”[enter]
*After you hit Enter Key, you will get: ‘>’ prompt, then type in your sms message then to send it, you must do ctr+z.
For example,
>This is your message[ctr+z]
3. If it is still not working for you, I suggest take out the SIM and put it in your cell phone and try it out and verify it if you can send the sms message with that SIM. Or you can try to plug in a different SIM to the iSMS device and see if it helps.
