Buy a Travel eSIM

If you want mobile data as soon as you land, a travel eSIM is the easiest way to get online without queuing for a kiosk or swapping out your home SIM card. It works on local mobile networks, so the coverage you get depends on the destination carrier, not on the eSIM itself.

Why travellers choose an eSIM

An eSIM is useful for short trips, multi-country itineraries, and anyone who wants to keep a home SIM active for calls, banking codes, or two-factor authentication. You can usually install it before departure, switch it on when you arrive, and start using data straight away.

  • No physical SIM swap when you land
  • Easy to keep your normal number active on dual-SIM phones
  • Helpful for airport arrivals, late-night landings, and transit stops
  • Often the simplest choice if you are visiting more than one country

eSIM vs physical SIM

Option Best for Main advantage Watch out for
eSIM Short trips, airport arrivals, and multi-country travel Instant setup and no SIM swapping Needs an eSIM-compatible phone
Physical SIM Longer stays and travellers who need local calls Can be cheaper for heavy data use in some destinations May require passport registration and a shop visit

For most travellers, an eSIM is the fastest way to avoid roaming charges and get connected immediately. A physical SIM can still make sense if you are staying longer, need a local number, or plan to use a large amount of data.

What to expect on arrival

In many airports, physical SIM counters are available, but queues, opening hours, and passport checks can slow things down. An eSIM removes that step. Before you travel, check that your phone is unlocked and supports eSIM, then install the plan while you still have reliable Wi-Fi.

If local registration rules apply at your destination, an eSIM can save time because activation is handled digitally. That said, some countries still ask for identity verification, so it is worth checking the destination requirements before you buy.

Which travel plan should you choose?

If you only need maps, messaging, ride-hailing, and email, a smaller data bundle is usually enough. If you stream video, hotspot a laptop, or travel with a second device, choose a larger plan from the start. It is often cheaper and easier than topping up repeatedly.

Practical tips before you buy

  • Check that your handset supports eSIM and is network unlocked.
  • Install the profile before departure if you want instant activation on arrival.
  • Keep your home SIM active if you need verification texts or emergency calls.
  • Use Wi-Fi to complete setup, then switch mobile data to the travel eSIM when you land.
  • Choose a plan that matches your trip length and data usage instead of overbuying.

Start with the simplest connection

A travel eSIM gives you a fast, low-friction way to get online overseas. It is especially useful when you want to avoid airport delays, keep your home number active, and manage mobile data from your phone before you leave.

FAQs

Frequently Asked Questions

Yes, you can use an eSIM in Travel if your phone supports eSIM and is unlocked for use with other networks. A Travel eSIM is a convenient way to get mobile data for maps, messaging, email and travel apps without needing to find a local SIM card after you arrive.

Your Travel eSIM connects through available local partner networks in Travel. Coverage can vary between cities, airports, main roads and more remote areas, so it is best to check the product details before you buy and allow for weaker signal in rural or hard-to-reach locations.

The best Travel eSIM plan depends on how long you are staying and how much data you normally use. Light users who mainly need messaging, maps and email can choose a smaller data allowance, while travellers using video calls, hotspot sharing or frequent photo uploads should choose a larger plan for extra peace of mind.

We recommend installing your Travel eSIM before you travel, while you have a reliable WiFi connection. You can then switch it on when you arrive in Travel. This helps you avoid airport queues, language barriers and unexpected roaming charges from your home network.

A Travel eSIM can often be a better-value option than standard international roaming, especially if your home network charges high daily roaming fees or expensive out-of-bundle data rates. You buy a clear data allowance in advance, making it easier to control travel costs.

You can use your Travel eSIM for practical travel needs such as booking transport, checking hotel details, using maps, messaging family, accessing email, translating phrases and keeping travel documents available online. It is especially useful when moving between airports, hotels, meetings and sightseeing locations.
