Through international roaming, a mobile communications service user may access such services while traveling internationally, enabling the user to make and receive calls, send and receive messages (SMS), send and receive other data (MMS and Internet), and access other service requirements by utilizing the mobile telephony network of one or more providers operating in the country where the user is located. International roaming enables you to use your portable computer when traveling abroad.
Roaming-related services, including the Internet access service, are typically more expensive.
It is important that users are aware that they may have been charged for accessing their e-mails, navigating the Internet, and viewing and downloading files (images, music, videos, or movies). The size (in bytes) of such data and files is relevant to the billing conditions.
Users of the national mobile network near border crossings may unintentionally use roaming when using their portable computers.
In such cases, users are charged roaming tariffs by the undertakings in their country, which are typically pricier than national ones, particularly for Internet access.
This roaming-related issue may result from different factors, including sporadic coverage service problems or momentary network gaps. However, it is impossible to prevent undesired roaming cases, which is why users should be informed about this issue and the relevant measures to avoid such events.
In order to avoid undesired roaming, users should contact their undertakings to learn whether the roaming service is enabled and what steps to take to permanently or temporarily disable it, or manually select the network of the national undertaking.
