eSIM Coupons: 28 Verified Brands | Sep 2026

An eSIM is a SIM card built into the phone itself, so a travel data plan can be installed by scanning a QR code instead of swapping a plastic card. Apple has sold iPhone 14 and later models in the United States without any physical SIM tray since September 2022, which pushed travel eSIMs from a niche into the mainstream.

Travel eSIMs let you land abroad with mobile data already working, usually for less than your home carrier's roaming charges. This category covers travel eSIM providers such as Airalo, Saily, Jetpac, Yoho Mobile, Roamless, Firsty, Global YO and eSIM4Travel, plus country and region specialists such as eSIM Japan and eSIM Europe.

For the trip itself, see Flights and Hotels, and for entry paperwork, Visas.

What this category covers

Does your phone support eSIM?

Most recent flagship phones support eSIM, including iPhone models from the iPhone XS and XR onward, Google Pixel phones from the Pixel 3 onward and recent Samsung Galaxy S and Z models. Many budget phones and some regional versions do not, so check your exact model before buying.

On an iPhone, go to Settings, then General, then About, and look for a Digital SIM or EID entry. Providers such as Airalo and Saily also list compatible devices.

Is your phone unlocked?

A travel eSIM only works on a phone that is not locked to a single carrier. Phones bought outright are usually unlocked, while phones bought on a contract may be locked until the contract ends.

Ask your carrier to unlock the phone before you travel. Trying to install an eSIM on a locked phone is one of the most common reasons it fails.

How much data do you need?

Maps, messaging and browsing use relatively little data, often well under a gigabyte a day. Video calls, streaming and using your phone as a hotspot for a laptop use far more.

Buy a plan slightly larger than you expect, or choose a provider that lets you top up easily. Most apps show how much data is left.

Country, regional or global plans?

Single country plans are the cheapest per gigabyte. Regional plans cover groups of countries, such as Europe or Southeast Asia, which suits trips that cross borders.

Global plans cover dozens of countries and cost the most per gigabyte. They make sense for frequent travelers and long trips across continents.

Data only or a local number?

Most travel eSIMs are data only, with no local phone number for normal calls and texts. Messaging and calling apps such as WhatsApp work over the data connection, which covers most travelers' needs.

If you need a local number, for example for taxis or deliveries, look for a plan that includes one. Your home SIM can stay active for texts, such as banking codes, while the eSIM handles data.

When should you install the eSIM?

Install it before you leave home while you have good WiFi, then switch it on when you land. Most plans only start their validity when they first connect to a network in the destination.

Turn off data roaming on your home SIM to avoid unexpected charges. Keep the QR code or activation details somewhere you can reach offline.

Which network will you use?

Travel eSIM providers use local mobile networks through partnership deals. Speed and coverage depend on that network, so check which partner the provider uses in each country, especially if you are heading somewhere rural.

Fair use and speed limits

Plans sold as unlimited often slow down after a daily amount of high speed data. Read the fair use terms so you know what speed to expect after that limit.

Do you need a travel eSIM in Europe?

Mobile plans from EU countries include roaming across the EU at no extra charge, under "Roam like at home" rules in place since June 2017. Visitors from outside the EU, including UK carriers that have reintroduced roaming charges, usually benefit from a travel eSIM.

Hotspots and connecting other devices

Many travel eSIMs allow hotspot use, letting a laptop or tablet share the phone's data. Some cheaper plans block it, so check before relying on it for work.

Removing an eSIM after the trip

An installed travel eSIM stays on the phone after the plan runs out, and some providers let you top up the same eSIM on your next trip. Deleting it frees the slot, but a deleted eSIM usually cannot be reinstalled, so only remove it once you are sure you will not reuse it.

Making an eSIM coupon go further

eSIM providers often give a discount on your first plan or credit for referring friends. Codes usually apply to one purchase, so use them on the largest plan you need.

Compare the price per gigabyte, not just the plan price, and check the validity period matches your trip.
