Summary
Mobile phones and wireless communications in general are kinds of technologies that have been deeply involved into social life as its essential part. The term “roaming” in wireless telecommunications refers to mobile users’ ability to continually realize their voice calls, send and receive messages, or access other services including home ones, and while traveling outside the borders of the geographical area covering the national telecommunications network service to use service network of the visited country at the same time. In practice this means that roaming ensures the wireless telecommunication devices (mainly mobile phones) to maintain a persistent connection to the home network without any interruption. If any higher priority networks are found, the mobile device stays on the visited network.
