Similar post to others. WIFI stopped working and started to use cell data. In 1 hour 30 minutes my phone incurred 181 euros of charges. Then SIMYO freeze it. They dont have the option to block out of bundle usage. So if something goes wrong, as it did here, you will end up with a huge bill.
This is not fair and not a good way to treat customers.
Contacted through Whats App and was told they sent a warning text. This was not received until after all the charges had been incurred.
