Mobile Vikings uses the network of mobile provider Telenet Group. That is why Vikings also surf the fast 4G network. Are you keen to find out whether 4G is available where you are? Then check out this map. If you are at a location where 4G is offered, it will be displayed on the screen of your smartphone as '4G' or 'LTE'.
Telenet Group currently uses a frequency of 1800 MHz for its 4G network. If you buy a device with a 4G function, make sure that it supports this frequency. This is especially important for devices bought abroad. The local frequencies may be different from those offered in Belgium or even Europe.
