What you actually pay
A carrier day pass runs about €10–15 a day, whether you use it or not. A Roamsim plan is a fixed price for a fixed allowance, bought once and used until it runs out — and validity only starts when you first use data, so buying early costs nothing.
No daily charges
One price up front. Nothing accrues while you sleep, and there's no bill waiting when you land back home.
Fair-use stated up front
Every unlimited plan shows its daily full-speed allowance and the speed after it — before you pay, not in the small print.
Real network, named
Each destination lists the carriers you'll actually roam onto and the network generation they reach, so 5G means 5G.

Questions, answered
Everything you need to know before your first eSIM. Still stuck?
Visit the help centerWill it work on my phone?
Most 2019+ flagships support eSIM — iPhone XS+, Pixel 3+, Galaxy S20+. Your phone must be carrier-unlocked.
When does my plan start?
Validity begins when the eSIM first connects to a network at your destination, not when you buy it.
Can I keep my main number?
Yes — the Roam eSIM is a second line, so your primary number keeps receiving calls and texts.
