The GSM modem operates in a similar way, except that it sends and receives data via radio waves rather than a telephone line. This type of modem can be an external device connected via a universal serial bus cable (USB) or a serial cable. More often, however, it is a small device that connects directly to the USB port or a card slot on a computer or laptop. Non -installed SIM card.

In this way, the GSM modem works just like a mobile phone; In fact many mobileThe phones also use SIM cards for the same purpose. Because the SIM card actually contains all subscriptions, membership and user data, these cards are usually interchangeable between GSM mobile phones and GSM mobile phones.
