GSM operators are mobile network operators that provide wireless voice and data services to subscribers. They are responsible for building and maintaining the GSM infrastructure, which includes cell towers, base stations, and switching centers. GSM operators also provide customer service, such as billing and technical support.

GSM operators divide their service area into small cells, each of which is served by a cell tower. When a user makes a call or sends a text message, their phone connects to the nearest cell tower. The cell tower then relays the call or text message to the GSM core network, which is responsible for routing calls and messages to the correct destination.

A virtual phone number is a phone number that is not associated with a physical SIM card. Virtual phone numbers are often used by businesses to provide customer support or to conduct marketing campaigns. They can also be used by individuals to protect their privacy.

The SMS code will be sent to the virtual phone number that you purchased. You will be able to access the SMS code by logging into your smscodehub's account.

Virtual phone number services are connected to physical services in a few ways. First, virtual phone numbers are often routed through the same network as physical phone numbers. Second, virtual phone number providers often partner with physical mobile operators to provide their services.
