GSM Gateways Cellular Terminals
What is a GSM Gateway?
A GSM Gateway (also known as Fixed Cellular Terminal, Fixed Wireless Terminal, Cellular Gateway) is a device that enables users to save money on calls from fixed phones to mobile phone networks.
In general, mobile to mobile calls are cheaper than landline to mobile calls. The GSM Gateway acts like a mobile phone, through which all company landline calls go to mobile networks.
Having one or more SIM cards installed in the GSM Gateway, you can make mobile to mobile calls instead of landline to mobile calls. GSM Gateways are sophisticated devices, and provide other useful features and options such as sending SMS, fax messages, etc.
Cellular GSM Gateways are mostly used for:
