SIM CARDS: TYPES, USES, AND FEATURES

A sim card simply means Subscriber-Identity-Module or Subscriber-Identification-Module, it is used to access connectivity to the telecommunications network for the communication services they provide.

A sim card gives us the ability to make and receive phone calls and SMS (Short Message Service), connect to data, and other value-added services. Users can subscribe to network providers either by Contract (Post-paid services that you use and pay later) or by Prepaid (pay for subscription services or airtime before use).
