Airalo provides eSIM options for individual countries, multi-country regions and global travel. Plan availability, supported networks and connection speeds depend on the selected destination and local mobile-network coverage.

What is an eSIM?

An eSIM is a digital SIM profile installed on a compatible phone, tablet or other device. Instead of inserting another plastic SIM card, you download and configure the mobile plan digitally.

This allows many travellers to prepare their mobile data plan before departure and connect after arriving at their destination.

Why use an eSIM for travel?

  • No additional physical SIM card is required
  • Installation can usually be completed before departure
  • Your regular SIM can often remain in the phone
  • Plans are available for different destinations and trip lengths
  • It may be more convenient than buying a local SIM after arrival

Why consider Airalo?

  • eSIM plans for more than 200 destinations
  • Local, regional and global plan options
  • Digital purchase and installation process
  • Different data allowances and validity periods
  • Plan management through the Airalo app or website

How it works

  1. Check that your exact device model supports eSIM
  2. Confirm that your device is not locked to another mobile network
  3. Choose a country, regional or global plan for your trip
  4. Review the data allowance, validity period and supported network
  5. Purchase and install the eSIM using reliable Wi-Fi
  6. Select the eSIM as the mobile-data connection when needed
  7. Enable data roaming for the travel eSIM when instructed

Check before purchasing

  • Your exact phone model supports eSIM
  • Your phone is not locked to a mobile provider
  • The plan covers your destination or travel region
  • The data allowance is suitable for your expected use
  • The validity period covers your complete trip
  • You understand when the validity period begins
  • You know whether the plan includes only data or also calls and SMS

What travellers use mobile data for

  • Maps and navigation
  • WhatsApp and other messaging services
  • Taxi and public-transport applications
  • Flight, transfer and hotel information
  • Restaurant and attraction reservations
  • Uploading photos and travel videos

Check device compatibility first

Not every phone supports eSIM. Compatibility can also differ between regional versions of the same device model.

Before purchasing, check that the exact device supports eSIM and is not restricted to another mobile network. A compatible but network-locked phone may not accept a travel eSIM.

Installation and activation

Install the eSIM while connected to reliable Wi-Fi and keep the installation instructions available. Avoid deleting the eSIM after installation unless the provider specifically instructs you to do so.

The validity period does not begin in exactly the same way for every plan. It may start at installation, activation or the first connection to a supported network. Check this before installing the plan.

Prevent unexpected roaming charges

Select the travel eSIM for mobile data and disable mobile-data switching if you do not want the phone to fall back to your regular SIM automatically.

Data roaming often needs to be enabled for the travel eSIM, while roaming on the regular SIM should remain disabled unless your normal provider includes roaming at your destination.

Data-only plans

Many travel eSIM plans provide mobile data only. They may not include a telephone number, regular voice calls or SMS messages.

Internet-based services such as WhatsApp can still work with a data connection. Your regular SIM may also remain available for calls and messages, depending on the phone settings and roaming costs.

Using two SIMs at the same time

Many compatible phones can use a physical SIM and an eSIM at the same time. This can allow you to use the travel eSIM for mobile data while keeping your regular number available for calls, messages or verification codes.

Receiving calls or messages through your regular SIM may still result in roaming charges. Check the roaming conditions of your regular provider before departure.
