The Mobilus subscription allows you to call, text and surf freely in Belgium and the European Union. If you use up more than what is included in your subscription or when travelling outside the EU, you have the option of exceeding your monthly bundle. You will then be billed at the applicable out-of-bundle rate. You can track your usage via MyProximus and through SMS notifications.
With Mobilus FullControl, you retain full control over your budget as you cannot exceed your monthly bundle. With a Mobilus FullControl subscription, your call minutes and MB will be automatically blocked once you have used them up. You can of course continue to send text messages limitlessly. If you have used up your bundle or you need to make calls, send text messages or surf the Net outside the European Union, you can top up with additional credit online, at the top-up rate.
