Hi ​@Andreika,

Thank you for your message. I'm sorry to hear that you incurred charges outside your bundle due to internet usage! 

We always send warning messages at 80% and 100% usage of your data bundle. These text messages come directly from the network and are always leading. In the last text message we also clearly indicate what the tariff is from that moment on (€0.15 per MB) and that it is wise to turn off the internet or to buy an internet bundle. From Simyo, we do our best to warn our customers in time. If you have incurred high costs outside your bundle within a short period of time, we will block your SIM card as a precaution and send an e-mail about this. 

We recently introduced the option to enable a data cap for €0.50 cents per month. This will prevent you from incurring charges outside your bundle again due to internet usage. We have also created a topic on the forum with detailed information about the data cap. You can activate the data cap through Mijn Simyo.

I understand that the costs were not made deliberately. Would you like to send me a private message with your 06 number and personal details? I'd be happy to see what we can do for you to resolve this together.

Greetings,
Roeqajja
