What if I have an option for mobile internet while abroad?

You automatically receive an SMS when you have used 90% and 100% of your option for mobile internet while abroad. What happens if you continue using mobile internet while abroad thereafter? And you have the notification service activated? Then you will receive an SMS when you have used an additional 90% and 100% of the standard limit (€60 incl. VAT).

Example
You have a 5 GB data roaming option. You will receive an SMS when you have used 4.5 GB (90%) and when you have completely used up the 5 GB (100%). What happens if you continue using mobile internet while abroad thereafter? And you have the notification service activated? Then, if you have a limit of €60, you receive an SMS after €54 (incl. VAT) of extra usage and €60 (incl. VAT) of extra usage. So when you receive the fourth SMS your data roaming will be blocked.
