Data Roaming Charges incurred even when Data Roaming was not switched on

Check Settings → Mobile Data → current period roaming. If Roaming is off it should be zero…

Thank you so much for the hints. My problem is that I had never cleared my data usage since I got the phone so now I have 535 GB for current period and 8.1 GB for roaming. 😢 From O2 app, I saw 0.4 MB for data used in Ausland. 

Hallo Andrea, does that mean even if data roaming is turned off I would still be charged? Mobile data was turned on but most of the time was on flight mode as I used only WiFi. I haven’t received the bills so far and only 2 SMSes from O2 saying I have reached the €59.50 limit, once for Turkey and the other time for Taiwan. I checked the O2 app for Ausland data usage and it was 0.4 MB. 

Hallo Andrea, I received my latest bill and there are no data roaming charges, phew! Not sure why I received the SMSes though but it was a good reminder to always turn off mobile data in addition to turning off data roaming while traveling outside of EU. Many thanks for your help and I wish you a fantastic weekend ahead!

Hey @Monamie80 ,

A fantastic weekend to you, too🌞

Hey @o2_Matea @o2_Andrea @o2_Jessica, 

I had the same issue today, I received the same message saying that I reached the amount of 59.50 € for data roaming, while I had moblie data and data roaming off before I even left germany, and left them off the whole time, it even says in my o2 app that I have 0MB of data used outside the EU.

Hey @SelimBY,

welcome to the o2 Community :)

Same question to you: Did you recive the bill alredy?

No I didn’t receive the bill yet, I just got the SMS

Hey @SelimBY,

Then we must first wait for the invoice and see if something was charged and to what extent and why :)

Greetings,
