An eSIM is a SIM card built into your phone. Instead of inserting plastic, you scan a QR code and your phone downloads a mobile plan. A travel eSIM is a data plan for another country that you add alongside your usual number.
How an eSIM works
Your phone can hold more than one plan at a time. You keep your home SIM for calls, SMS and bank OTPs, and use the travel eSIM for data. Most travel eSIMs are data-only, so apps like WhatsApp keep working with your usual number.
With eSIMKite, you install the plan at home on Wi-Fi. The plan starts when it first connects in your destination, so you don't lose days before you fly.
Does my phone support it?
Most phones sold from 2019 onward support eSIM, including the iPhone XS and newer, recent Samsung Galaxy models and Google Pixel 3 and newer. The phone must also be carrier-unlocked.
Quick check: dial *#06#. If you see an EID number, your phone supports eSIM.
eSIM vs roaming vs local SIM
| Travel eSIM | Home roaming pack | Airport SIM | |
|---|---|---|---|
| Set up | Before you fly, in minutes | Activate with your operator | After landing, in a queue |
| Your number | Stays on | Stays on | Replaced |
| Cost | Usually the lowest for data | Often the highest | Varies, tourist pricing |
| Best for | Most trips | Short trips, heavy calling | Long stays in one country |
Tips for your trip
- Install the eSIM at home on Wi-Fi, a day or two before you leave.
- Don't delete the eSIM after installing; you may not be able to reinstall it.
- When you land, switch mobile data to the eSIM line and turn on data roaming for that line only.
- Keep your home SIM on for OTPs, but turn its data roaming off to avoid charges.
