I just downloaded the NoW SMS Lite trial software. I am getting a message saying Modem does not properly support Command for sending SMS (AT+CMGS).

I am using Sierra Aircard 330U which I bought from Rogers store. It is locked by Rogers. However, Their communication manager can send the SMS.

I am wondering if i need to unlock to use it with your software?

Roger charges $50 to unlock. I just want to make sure that it will work if i unlock. Otherwise, i can return it with full refund and buy another one. Any suggestions, please.

Hi Naseem,

Sorry for the delay getting back to you.

The issue with Sierra Wireless Aircards is that the driver software for the Sierra Wireless modems actually installs several virtual COM ports for communicating with the modem.

One of these COM ports can be used for sending/receiving SMS messages, while the other COM port can only support data/internet connectivity.

With most Sierra Wireless modema, multiple virtual COM ports are installed by the Sierra Wireless software. However, a Windows modem driver is installed for only one of these COM ports, so when you select “Sierra Wireless HSPA Modem”, you are connecting to a COM port that only supports data/internet connectivity, not SMS connectivity.

To be able to send/receive SMS messages, it is necessary to identify the other COM port.

The following link will explain the process of identifying and using the correct port:
