Hi ​@Steveanne1952,

Yes, that's correct. The Roam Beyond add-ons are country-specific, so if you're planning to use mobile data in Serbia, Bosnia and Herzegovina, and Montenegro, you'll need to purchase a separate add-on for each country where you wish to use data.

The add-on purchased for one country won't work in another country, even if you're travelling between them on the same trip.

Before travelling, we'd recommend checking the roaming page below for the latest information on eligible destinations and available add-ons: https://www.idmobile.co.uk/help-and-support/roaming

Depending on how long you'll be spending in each country, you may also find that a local SIM or eSIM is a more cost-effective option.

I hope this helps, but if you have any other questions about your trip, please let us know.

Regards,
