About
Here we are going to show you how GSM gateway works. A GSM Gateway is a device that takes outbound calls and routes them using virtual SIM cards. Employees' routines are not disrupted because they just dial the number on their phones. The gateway then selects the most appropriate line for the call, avoiding costly call termination costs.
When contacting a mobile phone from a landline phone, GSM gateway devices can help you save money on your phone bill.
