If you are in a border area, we recommend that you change your network or operator selection from automatic to manual in the terminal settings, so that your calls or data connection are not transferred to a foreign network without your knowledge.
For more detailed instructions on how to change the selection, please refer to your terminal's user guide.
Always remember to check the network you are using after you have switched on the power to your terminal. For example, after a software update, the manual network selection may be switched on automatically.
Please note that you will be responsible for any costs incurred for using a foreign network.
