GPRS / GSM Modules and Modems

Although 2G cellular network transmission speed is slow, but the industry still has a very broad application space.

USR IOT provides GSM / GPRS Modules and GSM / GPRS Modems, which have the biggest advantage is the transparent transmission, simple to set up.

Low Power Gsm Modules, Small GPRS Modems

USR-GM3 is highly-integrated UART to GSM/GPRS module, Users can easily make communication with it among serial device,cellphone and network device.
