What is eSIM io?
eSIM io is a travel data app that lets you use mobile internet abroad without paying expensive daily roaming charges.
Instead of buying a physical SIM card at the airport or paying £5–£10 per day in roaming fees, you install a digital eSIM directly on your phone.
It works in dozens of countries and can usually be activated within minutes.

Why Use eSIM io Instead of Roaming?
Traditional roaming charges can add up quickly. Many UK networks charge daily fees to use your allowance abroad.
With eSIM io:
- You pay only for the data you need
- No physical SIM swap
- No contract
- Instant activation
- Often cheaper than airport SIM cards
It’s especially useful for:
- Short city breaks
- Remote work abroad
- Digital nomads
- Long-haul trips
Is eSIM io Legit?
Yes. eSIM io provides prepaid data packages that work via supported eSIM-compatible devices (iPhone XS and newer, most recent Android flagships).
Always check:
- Your phone supports eSIM
- Your device is unlocked
- Coverage in your destination country
eSIM io personal review (Chile and Brazil 2026)
I saw an offer and got the app to test it as I was in Chile and my esim stopped working (I got it from https://www.virginmobile.cl/planes), but my friend from Chile had to pay for it as none of my cards were accepted, and we need a RUT number, etc.
With eSimio, it was easy to install and use, and my Revolut worked to pay. No local identification needed.
Then, when I got to Brazil, I took a plan for 30 days just for Brazil. I tried to get an eSim with https://www.correioscelular.com.br/e-sim/#compraresim, but that didn’t work as well. So I gave up and keep using eSimio, it’s a bit more expensive but not that much (cheaper than most e-sim), and it gives you credit back for your next purchase. I was only in big cities, so zero issues.
Is the eSIM io Referral Code Worth It?
The $3 bonus isn’t life-changing, but it reduces your first data purchase and makes testing the service cheaper.
If you’re travelling soon, there’s no downside to adding the referral code before your first purchase.
Again, the working code is:
