How FairSIM works
Three steps between you and the internet abroad. Nothing to pick up at the airport.
- 1
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
- 2
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
- 3
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Popular destinations
Wholesale data rates in the places travelers go most. Each page tells you which network you get, how much data you need, and what to sort out before you land.
Why does using your phone abroad cost more than the flight?
Because roaming is priced for people who never check. FairSIM found the loophole: the real wholesale rate, sold without the markup.
Wholesale rates, zero markup
We hunt down the lowest network rates in each country and pass them on. No activation fee, no hidden margin, no surprise line on a bill, because there is no bill.
Data only, on purpose
Your physical SIM keeps your number for calls and two-factor codes. FairSIM handles the data. You never pay for a phone number you will not use.
One eSIM for every trip
Keep the FairSIM line on your phone. Next trip, buy a plan for the new destination in the app and it is live in seconds. Running low? Top up without reinstalling.

A roaming pass from a big carrier runs $10 to $12 a day. Ten days abroad is $100 or more. A 10 GB FairSIM plan is a fraction of that, and it does not expire at midnight.
What is an eSIM?
An eSIM is a SIM card built into your phone. Instead of swapping a plastic chip, you download a profile. Every iPhone since the XS has one, alongside the physical SIM slot, so your home number stays put while FairSIM supplies the data. Install it once, keep it, and load a new plan for each trip.
Frequently asked questions
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer. iOS 17.4 or later unlocks the one-tap install with no QR code. Check the full list on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
Can I use my physical SIM at the same time?
Yes. iPhones run both at once: your physical SIM handles calls and texts while the FairSIM eSIM handles data. Set FairSIM as the data line and turn off data roaming on your home SIM to avoid surprise charges.
What happens if I run out of data?
Top up directly in the app in seconds. No new plan, no new install, no waiting. The app shows exactly how much data you have left and alerts you before you run out.
Can I get eSIMs for family or friends traveling with me?
Yes. Buy and manage separate plans for the people you travel with, each with their own data, all visible in one FairSIM app. Nobody else has to download anything.
Are there any hidden fees?
No. The price on screen is the price you pay: no activation fee, no contract, no add-ons. FairSIM sells data at the wholesale network rate without a markup.
