Everything you need to know about the 4G Box

What is a 4G Box?

In general, the term "4G" refers to mobile Internet while "box" brings fixed Internet to mind. The 4G Box is an everyday solution, offering broadband Internet via 4G on all your devices (smartphone, tablet, computer, etc.). All you need is a 4G box and a SIM card to take advantage of POST's 4G high-performance network anywhere in Luxembourg. It is super easy to install as once the SIM card is inserted in the box, that's it: up to 64 devices can be connected to the Internet, via WiFi (the wireless solution) or with an Ethernet cable. So there's no need for technical support to install it and no waiting time. Turn it on, insert and enjoy!

The advantages of a 4G Box

  • It is THE solution for those whose fixed Internet connection is too slow or who are in a black spot (not eligible for fibre).
  • The 4G Box is available either with no minimum contract term or with a 12-month contract.
  • It comes in two versions –200GB or unlimited– and offers you a download speed of 100 Mbit/s and upload speed of 50 Mbit/s.
  • It is very easy to install and provides an instant Internet connection.
  • Are you interested in the 4G Box but you’re not convinced yet? Feel free to test it for 15 days and if you don’t like it, you may get a full refund.

Is the 4G Box for me?

The 4G Box is for anyone looking for an alternative to a fixed Internet solution. For example:

  • If your fixed Internet connection is too slow or you are in a black spot (not eligible for fibre)
  • If you are looking for an instant Internet solution for a temporary or specific need (apartment, office, building site, camping, events, etc.)

In both cases, the POST 4G Box is right for you. It can be used in the same way as a fixed Internet connection: for watching videos online, browsing, using social networks, sharing photos/videos, etc.
