Supported GSM Modems

NowSMS supports 2 types of GSM modems for sending and receiving SMS and MMS messages:

1.) USB or RS-232 connected GSM modems that support an “extended AT command set” for sending/receiving SMS messages, as defined in the ETSI GSM 07.05 and and 3GPP TS 27.005 specifications (AT+CMGS).

2.) Android devices running the NowSMS Modem app using either local WiFi or cellular data/internet connectivity. (Avoid dual SIM devices.)

As there are thousands of different device models and variations, we do not recommend specific devices.

However, we have begun asking recent customers which modems they are using, and will update this page with this information.
