General Questions

What is Airalo?
Airalo is a global eSIM marketplace that allows travellers to purchase and install local or regional data plans on compatible smartphones. It operates in over 200 countries and offers plans ranging from 500 MB to unlimited data. Airalo is not a mobile network operator itself; it partners with local operators in each country.
Is Airalo legitimate and safe to use?
Yes. Airalo is a well-established company founded in 2019, backed by reputable investors, and used by millions of travellers worldwide. It uses standard eSIM technology and processes payments securely. As with any online service, use the official Airalo app or website (airalo.com) to avoid counterfeit products.
What is AlrloService Guide?
AlrloService Guide is an independent information website based in Sheffield. We are not affiliated with Airalo Ltd. We provide free, unbiased information to help UK travellers understand and use Airalo eSIM services effectively.
Does Airalo provide a phone number?
No. Airalo eSIM plans are data-only. They do not include a phone number, voice calls, or SMS. You can make calls and send messages using VoIP applications such as WhatsApp, FaceTime, or Skype over the Airalo data connection.

Compatibility

How do I know if my phone supports eSIM?
On iPhone: go to Settings → General → About and look for "Digital SIM" or "eSIM". On Android: go to Settings → Network & Internet → SIMs and look for an "Add eSIM" option. You can also check our compatibility guide or search your device model online.
My phone is locked to EE/Vodafone/O2. Can I still use Airalo?
A carrier-locked device may restrict eSIM functionality. Contact your UK operator to request an unlock — this is typically free after your contract term. Once unlocked, you can use Airalo eSIM plans freely.
Can I use Airalo on a tablet or smartwatch?
Some tablets (e.g., iPad with cellular) and smartwatches (e.g., Apple Watch with LTE) support eSIM. However, Airalo's plans are primarily designed for smartphones. Compatibility with tablets and watches varies; check the Airalo app for supported devices.

Activation

When should I install the eSIM — before or after travel?
Install the eSIM profile before you travel, while you have a reliable Wi-Fi connection. However, do not activate it (switch to it as your data SIM) until you arrive in the destination country, as the plan may only work in the designated region.
Can I install the eSIM without Wi-Fi?
No. The eSIM profile download requires an internet connection. Use Wi-Fi at home, at the airport, or at your hotel before switching to the Airalo eSIM for data.
What happens if I scan the QR code on the wrong device?
Each QR code can only be used once and is tied to the device it is first installed on. If you scan it on the wrong device, contact Airalo support immediately. In some cases, they can issue a replacement code, but this is not guaranteed.
How long does activation take?
The eSIM profile download typically takes 30–90 seconds on a good Wi-Fi connection. Network registration after arrival in the destination country takes 2–5 minutes.

Coverage and Speeds

What data speeds can I expect?
In urban areas and popular tourist destinations, Airalo plans typically deliver 4G LTE speeds (10–50 Mbps download). In rural or remote areas, speeds may be lower (3G or 2G). Some plans offer 5G in supported countries.
What is a Fair Use Policy (FUP)?
Some "unlimited" Airalo plans include a Fair Use Policy, which means data speeds are throttled (reduced) after a certain usage threshold (e.g., 2 GB at full speed, then reduced to 1 Mbps). Check the plan details carefully before purchasing.
Does Airalo work in remote areas?
Coverage depends entirely on the partner network's infrastructure. In remote areas, coverage may be limited or unavailable even if the country is listed as supported. Check the partner network's coverage map for your specific destination.

Pricing and Refunds

Can I get a refund?
Airalo offers refunds for plans that have not been installed (QR code not scanned, profile not downloaded). Once installed, plans are non-refundable. Contact Airalo support promptly if you need to request a refund before installation.
Do unused data and validity days carry over?
No. Unused data and remaining validity days are forfeited when the plan expires. There is no rollover. If you need more data, purchase a top-up (if available) or a new plan.
Are there any hidden fees?
No. The price displayed on the Airalo platform is the total cost. There are no activation fees, monthly charges, or hidden extras. Your bank may apply a foreign currency transaction fee if the charge is processed in USD.

Troubleshooting

My eSIM shows as installed but data doesn't work
Check: (1) Is the Airalo eSIM set as your data SIM? (2) Is data roaming enabled for the Airalo SIM? (3) Are APN settings correct? (4) Try toggling Airplane Mode. (5) Restart your device. If still not working, contact Airalo support with your order number and device details.
How do I contact Airalo support?
Use the live chat in the Airalo app (fastest), or email [email protected]. Include your order number, device model, OS version, and a description of the issue. For questions about this information website, contact AlrloService Guide.

Glossary of Terms

eSIM (Embedded SIM)
A digital SIM built into your device that cannot be physically removed. eSIM profiles (carrier configurations) can be downloaded and switched digitally, allowing you to use different carriers without swapping physical SIM cards.
eSIM Profile
A digital configuration file containing the network credentials for a specific carrier. When you purchase an Airalo plan, you receive an eSIM profile that is downloaded to your device via QR code or the Airalo app.
QR Code Activation
The standard method for installing an eSIM profile. You scan a QR code provided by Airalo using your device camera, which triggers the profile download. Each QR code can only be used once.
APN (Access Point Name)
A configuration setting that tells your device how to connect to the mobile network's data services. Most Airalo plans configure the APN automatically, but some require manual entry. The correct APN details are provided in your Airalo account.
Data Roaming
Using mobile data while outside your home network's coverage area. Airalo eSIM plans are designed to provide local-rate data access, effectively replacing expensive traditional roaming charges from UK operators.
Data Throttling
A deliberate reduction in data speeds after a usage threshold is reached. Some Airalo plans throttle speeds after the stated high-speed allowance is consumed, rather than cutting off access entirely. Check plan details for Fair Use Policy thresholds.
Fair Use Policy (FUP)
A policy applied to "unlimited" data plans that limits high-speed data to a certain amount (e.g., 2 GB), after which speeds are reduced. This prevents network congestion and excessive usage by a small number of users.
Dual SIM
A device feature that allows two SIM cards (or one physical SIM and one eSIM) to be active simultaneously. With dual SIM, you can keep your UK number active for calls and texts while using an Airalo eSIM for data abroad.
