What is Roaming?

  • Roaming helps ensure that a traveling wireless device (typically a cell phone) is kept connected to a network without breaking the connection.
  • In wireless telecommunications, Traditional Roaming is a general term referring to the ability for acellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network. For example; should you travel beyond your cell phone company's transmitter range, your cell phone would automatically hop onto another phone company's service, if available.
  • National roaming: This type of roaming refers to the ability to move from one mobile operator to another in the same country.  In a country like India, where the number of regional operators is high and the country is divided into circles, this type of roaming is common.
