What is an eSIM?
A digital SIM built into your phone — buy a plan, install in minutes, land already connected.
A SIM without the plastic
An eSIM (embedded SIM) is a digital profile your phone downloads. Instead of swapping a physical card abroad, you install a Roamio plan over Wi‑Fi before you fly — and keep your regular number on your physical SIM for calls and WhatsApp.
Why travelers use eSIM
Skip airport SIM hunts
Install at home on Wi‑Fi. When you land, turn on the line and connect to a local network.
Know the price upfront
Transparent plan prices instead of surprise roaming bills from your home carrier.
Keep your number
Use eSIM for data while your regular SIM stays active for SMS and calls (dual-SIM).
Top up when you need more
Running low? Add data from your Roamio account without buying a new plastic SIM.
What you need
- An unlocked phone that supports eSIM (most recent iPhones and many Androids).
- Wi‑Fi to install the profile before travel (or at the airport).
- A Roamio plan for your destination — local, regional, or global.
