Airalo is an eSIM company that provides cellular data worldwide at a very affordable price. Users can access data connectivity options from countries around the world without removing their physical SIM cards.

What is Airalo?

Airalo is a platform that allows users to purchase eSIMs when travelling outside their home country. eSIMs are digital SIM cards that activate a phone plan without requiring a new physical SIM. This allows users to connect to the local network at their destination while continuing to use their phone as normal.

How Airalo Works

Airalo provides eSIMs for over 200 countries through its website and mobile app. You purchase an eSIM that meets your specific requirements — price, duration, data allowance — activate it, and you’re ready to use your phone as you would at home, including iMessage, WhatsApp, and mobile data.

Airalo’s Compatibility with Devices

Most current smartphones are compatible with eSIM technology, though some carriers may limit their use depending on your provider and the region where your device was purchased. Most phones manufactured from 2018 onwards support eSIMs, and users must have a carrier-unlocked device to use one.

Setup and Activation

After confirming your device is compatible, getting started is straightforward. Purchase your chosen eSIM through the Airalo app, select it, and follow the step-by-step instructions to complete setup on your phone. Once installed, select the eSIM as your mobile data provider and use your device as usual. Airalo also offers a YouTube tutorial, a help centre, and 24/7 support through its website and app.

Network Coverage and Speed

An Airalo eSIM provides data speeds and coverage comparable to what you’d experience at home. The same factors that can slow connectivity day-to-day — distance from cell towers, network congestion — apply when travelling too. In major cities, however, speeds and connectivity are generally seamless.

User Feedback and Testimonials

Airalo holds an average rating of 4.5/5 on Google Play and 4.6/5 on the iOS App Store, based on thousands of reviews accumulated over many years. Independent reviews from travel bloggers and Reddit users provide additional honest, unsponsored feedback for anyone wanting more firsthand perspectives before purchasing.

How Airalo Compares to Other eSIM Providers

Airalo vs. Holafly

Holafly has comparable app store ratings and has been operating two years longer than Airalo, giving it a slight experience advantage. It does tend to be pricier — some one-day Holafly eSIMs cost as much as a seven-day Airalo plan — though Holafly does offer unlimited data for the duration of the purchased SIM.

Airalo vs. Ubigi

Ubigi is perhaps Airalo’s closest competitor — both launched in 2017 and offer comparable pricing, validity periods, and data caps. Ubigi differentiates itself by offering monthly and annual eSIM rates, which may appeal to frequent travellers making multiple trips to the same destination each year. It also offers eSIMs compatible with Windows 11 devices.

Airalo vs. Traditional SIM Cards

Traditional SIM cards offer full phone functionality when travelling, but switching to a travel SIM means your existing phone number is no longer associated with your device. Physical SIM cards can also be lost, stolen, or damaged — none of which apply to an eSIM, which has no physical component.

Tips for Using Airalo Effectively

Checking Device Compatibility

Before purchasing, confirm that your device is eSIM-compatible and carrier-unlocked. Using an eSIM on a device still under contract with a carrier could result in additional charges, so it’s worth verifying beforehand.

Choosing the Right Data Plan

If you plan to use your phone mainly for GPS and maps while relying on hotel or hostel Wi-Fi for everything else, a lower-data plan will likely be sufficient. If you want unrestricted phone use throughout your trip, opt for a higher GB package. It’s always better to have slightly more data than you need than to run out mid-trip.

Troubleshooting Common Issues

Airalo’s help centre — accessible via its website and app — and its support helpline can assist with most issues. Community forums on Reddit and travel blogs are also useful resources for troubleshooting tips from users who have encountered the same problems.

Common Issues with Airalo and How to Resolve Them

Activation Problems

Airalo provides a setup guide and a YouTube tutorial with step-by-step activation instructions at the point of purchase. The 24/7 help centre on the website and app is also available for real-time support if any issues arise during setup.

Slow or Unstable Connection

After installing a new eSIM, restarting your device is a good first step — this resets all apps and allows the eSIM to initialise cleanly. Moving closer to a cell tower will also help improve speeds and connection stability.

Pros and Cons of Using Airalo

Pros

Affordable Data Plans

Airalo plans are significantly more affordable than standard roaming fees charged by most carriers. Some plans start at $5 USD for a 7-day validity period — a fraction of what many providers charge for a single day of international roaming, often with hidden fees on top.

Seamless International Connectivity

Once the eSIM is purchased and installed, connecting to the local network at your destination takes just a few taps. You can then use your device as normal for the entire duration of your trip.

Environmentally Friendly

With no physical SIM card involved, there is no plastic waste and no shipping emissions from transporting SIM cards to retail locations around the world. The environmental footprint is effectively zero.

Cons

Limited Device Support

Because eSIMs require carrier-unlocked devices, phones that are still tied to a carrier contract — often those offered “free” as part of a plan — may not be compatible with eSIM purchases until the contract period ends.

No Voice or Text Services

An Airalo eSIM provides data only — standard phone calls and SMS text messages are not supported. Workarounds such as WhatsApp calls or FaceTime are available for voice, but incoming SMS messages will not be received while using an eSIM.

Final Verdict: Is Airalo Worth It?

Airalo is worth it. With years of experience, consistently strong reviews, and a rapidly expanding global network, it takes the stress out of staying connected while travelling internationally. An Airalo eSIM will save both money and time compared to relying on your home carrier’s roaming rates.
