The short verdict
Ubigi and Airalo take different approaches to the same job. Ubigi runs on Transatel's own mobile core with a focus on fast 5G and connected devices — phones, but also laptops, tablets, and cars. Airalo is a marketplace that resells local carriers across more countries than anyone, with the most mature app. Ubigi often edges Airalo on 5G performance and device support; Airalo wins on coverage breadth and ecosystem. Both price above wholesale, so if you want the same capped data for less, Flysimio uses the same networks for roughly half the per-GB price. Pick Ubigi for 5G and non-phone devices, Airalo for coverage, and Flysimio for price.

Price: Ubigi vs Airalo
Ubigi's small starter plans can look cheap, but per-GB at typical travel volumes it sits close to Airalo — both well above wholesale. Real examples (competitor prices checked June 2026): a Japan 3 GB / 30-day plan is about $8 on Ubigi versus $5.25 on Flysimio; a USA 5 GB / 30-day plan is around $14.99 on Ubigi versus $7.75 on Flysimio; Europe 10 GB is roughly $19.99 on Ubigi versus $14.18 on Flysimio. Ubigi charges a premium for its 5G and device support; if you only need phone data, Flysimio is significantly cheaper on the same carriers.
5G, connected devices, and app
- Network: Ubigi runs on Transatel's own core and markets fast, reliable 5G; Airalo resells local carriers, so 5G availability depends on the specific plan and country.
- Devices: Ubigi supports laptops, tablets, and connected cars, not just phones — useful for remote work or in-car connectivity. Airalo and most travel eSIMs are phone-focused.
- App & coverage: Airalo has the larger app ecosystem and the most countries. Ubigi's app is solid and its direct-carrier model can mean smoother activation on supported hardware.
- Value: Flysimio sells the same capped phone data on the same tier-1 networks for roughly half Ubigi's per-GB price — the trade-off is no IoT/device plans and a simpler, web-based product.
Coverage and networks
Both cover a lot of ground — Ubigi around 190+ countries through direct carrier deals, Airalo 200+ through its marketplace. Ubigi's model can deliver strong, consistent 5G where it has direct agreements; Airalo's breadth means it almost always has something for obscure destinations. Flysimio covers 180+ countries and, in any given place, routes through the same dominant carriers as both — so real-world coverage is comparable and the difference is price and device support.
Which should you choose?
- Choose Ubigi if you want fast 5G or need to connect a laptop, tablet, or car — its device support and direct-carrier network are its strengths.
- Choose Airalo if you want the widest country coverage and the most full-featured app for phone data.
- Choose Flysimio if you want the lowest price on the same tier-1 networks for phone data, with a 7-day money-back guarantee.
Frequently asked questions
Is Ubigi or Airalo better?
It depends on your needs. Ubigi is better for fast 5G and for connecting non-phone devices like laptops, tablets, and cars, thanks to its direct-carrier network. Airalo is better for the widest country coverage and the most mature app. Both sell capped data above wholesale; if price is your priority, Flysimio undercuts both on the same carriers.
Is Ubigi cheaper than Airalo?
It is close and depends on the plan. Ubigi's small starter plans can be cheap, but per-GB at typical travel sizes it sits near Airalo. For example, a Japan 3 GB plan is about $8 on Ubigi. Both price well above wholesale — Flysimio is cheaper than either, around $5.25 for that Japan plan on the same carrier.
Does Ubigi support 5G?
Yes. Ubigi runs on Transatel's own mobile core and markets fast 5G as a key differentiator, along with support for laptops, tablets, and connected cars. Airalo's 5G availability depends on the specific local plan it is reselling.
Can I use Ubigi on a laptop or car?
Yes. Ubigi is one of the few travel eSIM providers with native plans for laptops, tablets, and connected cars, not just phones. Most travel eSIMs, including Airalo and Flysimio, are designed for phones. If you need connectivity on non-phone devices, Ubigi is the stronger choice.
What is a cheaper alternative to Ubigi and Airalo?
For phone data, Flysimio is a cheaper alternative — it runs on the same tier-1 carriers but is typically about half the per-GB price, with plans from $1.75 and a 7-day money-back guarantee. The trade-off is that Flysimio does not offer IoT/device plans or a large app.
