How eSIM technology makes staying connected abroad simple.
A travel eSIM is a digital SIM card you download to your phone instead of inserting a plastic one. It holds a prepaid data plan for the country you are visiting, so you get local mobile data without roaming charges or hunting for a SIM on arrival.
Travelling to a new country is exciting, but staying connected abroad hasn't always been easy. Many travellers still face expensive roaming charges or the inconvenience of searching for local SIM cards upon arrival.
With an eSIM, you can activate mobile data in minutes without inserting a physical SIM card. For frequent travellers, digital nomads, and business professionals, this technology offers a simple and flexible way to stay online anywhere in the world.
Let's explore how travel eSIMs work and why they are quickly becoming the preferred solution for international connectivity.
What is a travel eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone or tablet.
Instead of inserting a physical SIM card, you install a mobile network profile digitally on your device. Once activated, the eSIM works just like a traditional SIM card and connects your phone to a mobile network so you can use data, calls, and messaging services.
The key difference is that everything happens digitally, which removes the need for physical cards. This makes switching between mobile plans faster and much more convenient.
How does a travel eSIM work?
You buy a plan online and receive a QR code by email. Scanning that code installs the network profile on your phone, which takes a couple of minutes on Wi-Fi at home.
The plan does not start counting down when you buy it. It starts when your phone first connects to a mobile network at your destination, so you can install it days before you fly. Check your handset first on our device compatibility page, and follow the eSIM installation guide when you are ready.
Why eSIMs are perfect for travellers
For people who travel internationally, eSIM technology makes staying connected much easier. Here are some of the biggest advantages.
Instant setup
You can purchase and activate an eSIM online in just a few minutes. There's no need to visit a store or wait in line at airport SIM kiosks.
Multiple plans on one device
Most modern smartphones allow you to store several eSIM profiles. This means you can easily switch between different data plans when travelling between countries.
No physical SIM cards
Since everything is digital, there's no risk of losing or damaging a SIM card while travelling.
Lower data costs
Travel eSIM plans often provide much cheaper mobile data compared with international roaming from your home carrier. We compared the actual figures in eSIM vs roaming for NZ and Australian travellers.
Choosing the right eSIM plan for your trip
The best eSIM plan depends on your travel habits and destination.
Before selecting a plan, consider where you are going, how long you'll stay, and how much mobile data you usually use. Here are some common types of travel eSIM plans.
Global plans
Global eSIM plans are ideal for travellers visiting multiple countries or continents during the same trip.
With a global plan, you can move between destinations such as New York, Paris, or Tokyo without changing your SIM or installing a new profile.
Regional plans
Regional eSIM plans cover multiple countries within a specific region, such as Europe or Asia.
These plans are often more affordable than global options and work well for travellers focusing on one area.
High data plans
Some travellers rely heavily on mobile data for navigation, video calls, social media, and work.
High-data plans offer larger data allowances so you can stay connected without worrying about running out of data.
How much mobile data do travellers usually need?
Mobile data usage depends on how you use your phone while travelling. Navigation and messaging use very little — Google Maps is only about 5 MB an hour. Video is what drains a plan, whether that is streaming, Reels or a video call home.
For a full per-app breakdown with sources, see how much data you actually need, by app.
As a rule of thumb:
- Light use (maps, messaging): 1–3 GB per week
- Moderate use (social media, browsing): 3–7 GB per week
- Heavy use (video calls, streaming): 10 GB or more per week
Choosing a plan that matches your travel habits helps ensure you stay connected without running out of data.
Tips for using eSIMs while travelling
To get the best experience with a travel eSIM, keep these tips in mind:
- Install your eSIM before departure if possible
- Choose a regional or global plan for multi-country trips
- Monitor your data usage during longer trips
- Check network coverage for remote areas
In most major cities and popular travel destinations, eSIM plans provide fast and reliable mobile data.
Frequently asked questions
What is a travel eSIM?
A travel eSIM is a digital SIM card you download to your phone instead of inserting a plastic one. It holds a prepaid data plan for the country you are visiting, so you get local mobile data without roaming charges or hunting for a SIM on arrival.
How does a travel eSIM work?
You buy a plan online and receive a QR code by email. Scanning it installs a network profile on your phone. When you land, the eSIM connects to a local partner network and your data plan starts. Your usual SIM can stay active alongside it.
Do I need to remove my normal SIM card?
No. Most phones from the last few years run two SIMs at once, so your home number stays active for calls, texts and banking codes while data runs through the eSIM. Set mobile data and data roaming to the eSIM only to avoid home carrier charges.
