Answer 1

mobile phone operator, wireless provider, or carrier is a mobile telecommunications company that provides wireless Internet GSM services for mobile device users. The operator gives a SIM card to the customer who inserts it into the mobile device to gain access to the service.

There are two types of mobile operators:

a mobile network operator (MNO) which owns the underlying network and spectrum assets required to run the service.

a mobile virtual network operator (MVNO) which buys wholesale service from an MNO and sells on to its own customers.
