Roaming costs despite WLAN use
If mobile data usage is activated on your mobile phone, it can happen that unwanted automatic connections are established.
To avoid this happening in future, you can block your data connections while abroad in my yallo under "Settings".
Roaming costs without staying abroad
In Swiss border regions, your mobile phone may automatically connect to networks in these regions due to more powerful antennas.
To avoid this roaming connection, you can adjust the settings of your mobile phone on our network to default manually. Alternatively, it is also possible to block the roaming function in my yallo under "Settings".
