A roaming SIM is a mobile phone SIM card that operates on more than one network within its home country. Roaming SIMs currently have two main applications, the least cost call routing for roaming mobile calls and machine to machine. Using a normal network locked SIM, travelers can use their own roaming enabled mobile phone in any country that has a roaming agreement with their home network, or for global networks like Vodafone, with another Vodafone OpCo. This manifests itself to most users when they receive a text message welcoming the traveler to a local network. Once they return home, their SIM will only work on the network with which they have a contract. A roaming SIM however, also known as a global roaming SIM, will work with whichever network it can detect, at home or abroad.
