Hi @Denis Burdukov,

Thank you for your message. I can imagine that you were shocked by these cost.  At Simyo, we do not currently have a data cap, so it is the customer's responsibility to switch off mobile data at the end of the bundle. 

Simyo will however, always send you two warning SMS messages when you have reached 80% and 100% of your internetbundle. The app is not always in sync with your actual usage, but the text messages we send are directly from the network and are always correct. To avoid high costs, it is advisable to switch off the 4G phone as soon as you receive the text message at 100%. 

It is important to know that as long as the internet connection on the SIM card is active, there is always a chance that data will be used, both consciously and unconsciously. This can happen, for example, through updates or applications that remain active in the background. 

Of course I understand that this was not intended on your part. This is why I would like to take a look at your subscription with you. Can you send me a private message? Then I can ask you for some personal information. In addition, this blog with tips and information can be useful to avoid high costs in the future.

Greetings,
Seren
