Koala Sim vs Airalo: Is Airalo’s “Unlimited” Data Actually Unlimited?
Last updated: January 2026
Short answer
Koala Sim offers genuinely unlimited data with no fair usage policies, no speed throttling, and unlimited hotspotting. Airalo’s unlimited plans are governed by fair usage rules and speed management, which can affect performance during normal travel use.
This comparison is informed by hands-on international travel usage, published provider terms, and direct operational insight from within the travel eSIM industry.
Key difference: Some eSIM providers define unlimited data through policies and limits, while others define it by consistent real-world performance across a trip.
If you want a clear explanation of how terms like unlimited data, fair usage policy, speed throttling, and hotspot limits are commonly defined in the travel eSIM industry, we explain them in our Travel eSIM Definitions Hub.
Many travellers buy unlimited eSIM plans assuming their phone will work the same way every day of their trip. In practice, unlimited can mean very different things depending on how a provider manages speed, usage, and hotspot behaviour.
Key differences at a glance
| Feature | Koala Sim | Airalo |
|---|---|---|
| How “unlimited” is defined | Unlimited data with no fair usage policy | Unlimited data governed by fair usage rules |
| Speed management | No speed throttling | Speeds may be reduced under fair usage conditions |
| Fair usage policy | No fair usage policy applied | Fair usage policy applies to unlimited plans |
| Hotspot / tethering | Unlimited hotspotting supported | Hotspot performance may be affected by speed management |
| App requirement | No app required | App required to install and manage the eSIM |
| Activation timing | Installed at home and activates automatically on arrival | Activation requires app access and user setup on arrival |
TL;DR
- Airalo unlimited plans operate under fair usage rules.
- Airalo speeds may be reduced during sustained usage.
- Airalo hotspot performance is often impacted first.
- Koala Sim provides unlimited data with no speed throttling.
- Koala Sim includes unlimited hotspotting and automatic activation.
Airalo states that its unlimited plans are subject to fair usage rules. In real-world use, this means speeds may be slowed once certain usage patterns are detected. At reduced speeds, connectivity is often limited to basic messaging and other low-bandwidth tasks.
Koala Sim takes a different approach. The eSIM is installed onto your phone at home before you travel. Once you arrive in your destination country and the eSIM connects to the local network, it activates automatically without any further action.
This difference is especially noticeable when hotspotting. On plans where speed is managed, hotspot traffic is often deprioritised first. With Koala Sim, hotspotting works consistently throughout the trip without hidden limits.
Who is each option better for?
Choose Koala Sim if you care about:
- Using your phone normally while travelling (social media, streaming, messaging, and video calls)
- Consistent data performance every day of your trip
- Unlimited hotspotting for laptops or shared devices
- No unexpected speed drops mid-trip
Airalo may be sufficient if you only need:
- Maps
- Basic messaging
- Very light usage where reduced speeds are unlikely to matter

After testing multiple “unlimited” travel eSIMs across several international trips, speed throttling and hotspot restrictions were the most common failure points.
We’ve also compared Koala Sim against Holafly, Simify, TravelKon, and Saily to show how different “unlimited” eSIM plans behave in real-world travel.
Frequently asked questions
