Wi-Fi and mobile internet (3G/4G)


Wi-Fi connects to the Internet over a wireless network and its coverage is limited to a building or a particular area.

At home

Are you a Proximus Internet customer? If so, you’ll have a private Wi-Fi network through your B-Box modem. By logging into this network with your smartphone or tablet, you use your fixed Internet volume (and not mobile Internet volume).

Outside your home

Wi-Fi is available:

  • via the Wi-Fi Hotspots: the Proximus Internet subscription allows you to connect to the Wi-Fi Hotspots free of charge: completely securely, you share part of your own Wi-Fi network at home and, in exchange, you enjoy free access to the Wi-Fi network of all other members. This allows you to surf via more than 1 million Wi-Fi Hotspots in Belgium and more than 14 million Wi-Fi Hotspots abroad! When doing so, you use your fixed Internet volume.
  • in public places such as cafés, airports and shopping centers. These hotspots may be public or private, free or paying.

To surf via Wi-Fi on your mobile, your device must be Wi-Fi-compatible.

3G/4G (mobile Internet)

Mobile Internet (3G/4G) uses the mobile telephony network. With your SIM card, you can access the Internet anywhere, whether you're in Belgium or abroad. In Belgium, Proximus's 3G network covers the whole country, while the 4G network already covers 85% of the population.

As a Proximus customer, mobile Internet volume is included in your Internet subscription and in most mobile subscriptions. If that’s not the case, we recommend that you choose a mobile Internet option so you pay less for your data consumption.

To surf via 3G or 4G on your mobile, you need a 3G- or 4G-compatible device.

When should you use Wi-Fi and when 3G/4G?

Check whether you can connect via a free Wi-Fi network, otherwise connect to the 3G/4G network.

If you’re at home

Use your personal Wi-Fi network.

If you’re outside your home in a café or park, at a friend's place, etc.

See if there’s a Wi-Fi Hotspot or a free open Wi-Fi network nearby. If there isn't, use your mobile Internet volume.

If you’re outside your home in a car, bus, tram, etc.

While on the move, it's better to use the 3G/4G network.

If you’re abroad

See if there’s a Wi-Fi Hotspot or a free open Wi-Fi network nearby. If there isn't, have you considered an option allowing you to surf more cheaply abroad?
