How can I protect myself from unexpectedly high invoices ?

Do you sometimes get caught by surprise by high amounts gracing you telecom invoice?

When traveling to another country you have undoubtedly received free text messages informing you of roaming tariffs for calling, texting and mobile Internet. And very possibly you have received from time to time a free message stating that you had already consumed a certain amount (about 50 euros, excluding VAT) or a certain volume.

A similar system was introduced on 1 February 2014 for mobile communications within Belgium.

You can also avoid high bills by asking your operator to block calls to specific numbers or texting at premium tariffs. That system is free as well.
