Thank you! Yes, I recall signing up for Travel & Surf.

Hello @Dwakser,

as @RoadrunnerDD has already correctly written, there are additional roaming charges for outgoing and incoming calls abroad.
Unfortunately, you have only booked data passes for abroad, which only included free data usage.

This is the reason for the additional cost of the phone calls.

Kind regards

Malte

Thanks. I will try to keep that in mind the next time I go on a trip.

but I have questions about some of the charges

Primarily, this is a customer-help-customer community. So please ask your questions. Which items on your invoice do you not understand? What exactly is different to the last invoice? Have positions been added? Which?

But isn't that the purpose of the plan I purchased? To avoid those costs? That is what is confusing to me. Also, it shows I purchased TWO plans, though I don't know how that happened.

Also, it shows I purchased TWO plans

Are you sure you booked only one of them? Then we can call the @Telekom-hilft-Team to look into this issue

I recall distinctly that I was attempting to do this from my phone - but most of the screens are in German. I might have done something wrong. 

Yes - I didn't notice that. I am not used to these things. Thanks to all.
