So what’s an eSIM, really?
Think of it as a SIM card with the plastic part missing. It’s a small chip already inside your phone that can hold multiple carrier profiles at once — including ours.
Activate it digitally, swap profiles when you cross a border, leave your home line untouched. No tools, no shops, no hunting for a paperclip in an airport.

WHY eSIM TRAVEL
Three reasons travelers don’t go back.
Faster than picking up a local SIM. Cheaper than roaming. Less hassle than either.
No bill shock
Pay once, in advance, for exactly the data you need. Your carrier’s roaming charges don’t fire — they don’t even know.
Keep your number
Your physical SIM stays in. Calls and texts still hit your home line. You just route data through the eSIM.
FREQUENT QUESTIONS
The five things people always ask first.
Short answers. Real ones. The kind we wish we’d had before our first international trip.
01Is my phone compatible with eSIM?
Most phones from 2018 onward are. Quickest test: paste your model into our device check tool. If it’s not supported, you’ll see that in a second — no commitment.
02When does my plan start counting down?
The day your eSIM first connects to a network in your destination — not the day you buy it. Install weeks ahead with zero penalty.
03Will calls and texts still reach me?
Yes. Your home SIM stays in place and active for voice and SMS. You just route data through our eSIM. Best of both worlds.
04What if it doesn’t work when I land?
Our help center has a 5-step troubleshooter that fixes most cases in under 2 minutes. If it can’t be fixed, we refund and replace — no questions.
05Can I top up if I run out of data?
Yes — from the same eSIM, no need to install anything new. Top-ups appear instantly in your account.
