Prices depend on the country, the amount of data and the number of days. We check prices daily, so these figures are up to date. Sort the table above by price or by price per GB to compare.

RoamVault has plans for 18 countries and territories. To see the plans for your destination, choose it under Filters next to the plans.

Yes, you can buy a RoamVault eSIM in advance, but you must activate it within 2 months of purchase, or it expires with no refund.

The days start when you first use data, not when you buy or install. You buy RoamVault eSIMs through MobiMatter, which suggests installing 1–2 days before your trip, keeping the line off, and switching it on with data roaming when you arrive.

Don't delete the eSIM to reinstall it later, as it may not come back.
