If travelling by boat on open water or during a flight, your mobile phone may connect to a non-terrestrial network (for example, a satellite network provided on board the aircraft or boat). These services are not covered by ‘roam like at home’ and may have high surcharges. As part of the roaming rules, you will be informed with a notification about additional charges for using roaming services on so-called non-terrestrial networks.
In order to help you avoid unexpected charges, if your mobile phone connects to a non-terrestrial network, you should receive an automatic message from your mobile network provider to alert you. Your mobile services should be interrupted automatically by your mobile network provider if you continue using your phone (or if apps using mobile data continue running on your phone) and you reach €61.50 (including VAT) of additional charges (or another predefined limit).
Mobile providers may offer additional services such as the possibility to opt out from roaming on planes and boats.
