How eSIMion works
eSIMion gets your phone online in another country before you even pack. You email us your trip. We email you an eSIM. There is no app to download and nothing to install except the eSIM itself.
Getting started
You need two things. A phone that supports eSIM and an email address.
That is the whole list. You do not need to download an app. You do not need to create an account first. You do not need to be on fast Wi-Fi. Everything happens over email, so it works even on a slow hotel connection or spotty airport Wi-Fi.
Most phones sold since 2018 support eSIM. If you are not sure about yours, check our device compatibility page. It takes one minute.

What is an eSIM?
An eSIM is a SIM card that lives inside your phone as software. There is no plastic card to insert and nothing to lose.
A travel eSIM adds mobile data for the country you are visiting. Your regular SIM stays in place. Your phone number does not change. When the trip ends, you turn the travel eSIM off and your phone is back to normal.
We cover the full picture on our What is an eSIM page, including how it sits next to your home plan.

Why use eSIMion?
No app. Ever. Other eSIM sellers make you download their app to buy and install. With eSIMion the whole thing happens in your inbox. Your eSIM arrives as an email with a tap-to-install link and a QR code.
Because it runs on email, it works when your connection is bad. An email loads on a weak signal where an app store download will not.
We also do something nobody else does. When you tell us about your trip, we reply with four plan tiers so you choose what matters most. More on that below.
Data plans in 200+ countries. Pay once, no surprise roaming bill. Run low on data and a top-up is one email away.
How to order
The easiest way is email. Forward your flight confirmation, hotel booking, or any trip email to trips@get.esimion.com. That is the whole job. We read your destinations and dates and reply with plans that fit your exact trip.
Prefer to browse? You can also pick a destination yourself and buy a plan directly. Both roads end the same way, with an eSIM in your inbox.
Install takes one tap on most iPhones. On other phones you scan the QR code in the same email. Your eSIM is ready before you fly and switches on when you land.
Need more data mid-trip? Email us and say "top up." We reply with a one-click link.

Four tiers, your choice
Every trip has a tradeoff. Price, coverage, or simplicity. Instead of guessing what you want, we show you four options and let you pick.
Best Coverage
The strongest network match for every stop on your trip. Pick this when being reachable matters more than price. Good for work trips and remote areas.
Best Value
The sweet spot. Solid coverage and enough data for the length of your trip, at a fair price. Most travelers pick this one.
Lowest Price
The cheapest way to stay connected. Good for short trips, light users, and anyone who mostly lives on Wi-Fi.
Global Simplicity
One eSIM for the whole trip, even across many countries. No switching plans at each border. Good for multi-country trips and cruises.
You get all four in one email and pick with one click. No other eSIM service explains your choices this way.
How pricing works
Every trip is priced on its own. You send your destinations and dates, and the reply shows current prices for all four tiers.
We do it this way because plan prices come from live provider catalogs and change. A price printed on a page goes out of date. A quote made against your real trip does not.
Start with one email. Forward your trip email and your eSIM options arrive in minutes.
