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.
Ready to roam?
Set up your first eSIM in under two minutes. Cancel anytime.
