ROAMING

Mobile telephone network roaming refers to the ability of a mobile phone to connect to and use a different network than its home network when traveling outside its coverage area.

This allows users to make and receive calls, send texts, and access data services even when they are in a different city or country.

Here's how it works in simple terms:

Automatic Network Switching: When you travel beyond your home network's coverage, your phone automatically connects to a local network in the area you are visiting. This is possible because your home network has agreements with other networks to allow roaming.

Service Continuity: Roaming ensures that you can continue using your phone for voice calls, messaging, and data without interruption, even when you are abroad.

Charges and Billing: The visited network records your usage and sends the details to your home network. Your home network then bills you for these services, often at higher rates than your usual plan.

Roaming is essential for maintaining connectivity while traveling, but it can result in additional charges, especially when roaming internationally.

However, some regions like the European Union have regulations that cap these charges for users.
