Free SIM cards, PAYG or contract, unlimited text deals
Different mobile networks offer different prices for their various services and some have better or worse mobile coverage in a certain region or for a certain technology. For example, some networks are Pay As You Go (PAYG) only and some offer contracts. Many networks give out free SIM cards or have offers that provide unlimited texts for a certain price. Others even have the option of unlimited data or unlimited calls.
Mobile telecommunications
One essential characteristic that defines a mobile network operator is that they must have acquired a radio spectrum license from government agencies before they can provide a mobile phone service on the airwaves within a country. The extent of the spectrum obtained depends on the type of mobile phone technology the operator intends to deploy. For example, GSM and 3G communications require a different frequency range. The operator must also deploy essential equipment in order to offer the services, most notably the radio transmitter network and the core network.
