What is GSM Gateway?

GSM Gateway is a device connected to the fixed phone or fixed telephone exchange which by a SIM card directs calls from fixed telephony to mobile telephony. When a user calls a mobile phone from his fixed number, the call bypasses the fixed telephony network and is directed directly to GSM network. In this way, although a user is calling from a fixed phone, he is making the call within the mobile network.
 

Cost reduction

The main benefits from using the GSM Gateway are large savings on fixed phone bills. By using the Gateway a company eliminates calls from fixed lines to mobile phone numbers, which are, as a rule, several times more expensive than calls made within the mobile network.
 
In this way you can save up to 70% on your fixed phone bills.
