Do You Need an eSIM for International Travel?

Short answer: You don't need one, but a travel eSIM is usually the cheapest way to have data abroad. You buy a data plan online, scan a QR code, and your phone has internet when you land. Your phone has to support eSIM and be unlocked.
Your options abroad are your own carrier's roaming, a local SIM card at the airport, or a travel eSIM. Here's how a travel eSIM works, what it costs, and how to set one up, with prices we checked on SimKeep's site on Nov 9, 2026.
What a travel eSIM is
An eSIM is a SIM built into your phone. Instead of swapping a plastic card, you install a data plan with a QR code or a link. Your regular SIM stays in, so you keep your number for calls and texts over Wi-Fi.
Most travel eSIMs, including SimKeep's, are data only. There's no local phone number, so you call and text with WhatsApp, FaceTime or similar apps.
What a travel eSIM costs
Prices depend on the country, how much data you need and for how long. Here are SimKeep's France plans as shown on its site on Nov 9, 2026, at its sale prices:
| Plan | Price |
|---|---|
| 1 GB, 7 days | $3.59 |
| 3 GB, 30 days | $6.29 |
| 10 GB, 30 days | $12.52 |
| 20 GB, 30 days | $18.74 |
Regional plans cover several countries on one eSIM. SimKeep's Europe plan covers 44+ countries and its Global plan 132+. Prices change often, so check the plan page before you buy.

eSIM vs your carrier's roaming
Many US carriers sell day passes for travel. For example, Visible lists its Global Pass from $5 a day on its plans page. On a week-long trip, a day pass adds up fast, while a 7 or 30 day eSIM plan is one flat price. Roaming is easier, since there's nothing to install, and you keep your normal number for regular calls.
A good mix for many people: keep your normal line on for texts and calls over Wi-Fi, and use the eSIM for data.
How to set up a travel eSIM
- Check your phone. It needs to support eSIM and be carrier unlocked. SimKeep's How It Works page has a device check.
- Buy the plan before you go. Pick your country or region and data size. SimKeep sends the QR code by email after you pay.
- Install it at home on Wi-Fi. Scan the QR code in your phone's settings, under Cellular or Mobile data, then add the eSIM.
- Switch it on when you land. Set the eSIM as your data line and follow your plan's activation instructions.
Tips so it works the first time
- Install the eSIM a day before you fly, while you still have Wi-Fi.
- Turn off data roaming on your home line so it doesn't run up a bill.
- Going to more than one country? A regional plan is often cheaper than two single-country plans.
