Hi ​@Martin_Simmy,

Welcome to the Community!

We don’t offer roaming add-ons for Montenegro. You can still use services there but they would be chargeable. You can find further information regarding charges at the link below:

That's exactly my point, how do I get a refund for an add on that I can't use as I am in Montenegro?
