If you cannot text, there is very likely something wrong with your text message centre. If so, you will need to check it in your device. You can use one of two numbers: +32486000005 or +32456002000. If the one number does not work, please try the other one.
iPhone users can configure the text message centre by dialling the code 5005*7672+32486000005# or 5005*7672+32456002000# and pressing the call button.
All other users can enter the centre in the device settings (usually the settings for your text message app).
Afterwards, restart your device and try to send a text message to yourself. If this does not work, please call us so we can help you.
