Overview
Ubigi has built a reputation as one of the best-value travel eSIMs — often the cheapest and among the fastest in Europe and Asia. It's a subsidiary of Transatel, now owned by NTT (Japan's largest telecom), which gives it strong carrier access. This review examines whether the reputation holds and who Ubigi is genuinely best for.
What is Ubigi?
Ubigi is an eSIM provider founded in 2017, based in Paris, France, and now a subsidiary of NTT Group. It covers 200+ destinations with a wide range of prepaid data plans including some unlimited options. Ubigi's key differentiator is pricing — it frequently undercuts major competitors in European and Asian markets. It also offers monthly recurring plans in 20+ countries, making it an option for regular business travelers. The company has MVNO infrastructure, giving it more direct carrier relationships than pure resellers.
Ubigi Pricing: Why It's Usually the Cheapest
Ubigi's direct carrier relationships via NTT's global network enable lower wholesale rates than reseller-model competitors. In Europe, Ubigi regularly prices 20–40% below Airalo and Holafly for equivalent data. In Asia, it's competitive with Nomad for the top value position. A 10GB/30-day Europe plan typically runs $12–18 on Ubigi vs $20–30 on Airalo. Unlimited monthly plans are available in select countries, often cheaper than Holafly's equivalent. The trade-off: the app is bare-bones and plans under 5GB are limited.
Ubigi Speed Performance: Often the Fastest
In independent speed tests, Ubigi consistently ranks in the top 2–3 fastest eSIMs in Europe and Asia. Its NTT-backed carrier relationships provide access to premium tier-1 networks in most major destinations. In the UK, Ubigi has consistently clocked top speeds among tested providers. In Asia, it competes directly with Nomad for the top speed position. The speed reputation is real and well-documented across multiple independent testing publications.
Ubigi Pros and Cons
Pros: frequently the cheapest and fastest option in Europe and Asia, 200+ country coverage, NTT-backed carrier access, monthly plans available in select markets, hotspot supported, unlimited plan options in some countries. Cons: app is functional but outdated and unintuitive compared to Saily or Airalo, logs users out regularly which disrupts plan management, no rewards/loyalty program, limited plan options under 5GB, customer support described as slower than Saily or Holafly, AI chatbot support of inconsistent quality.
Who Should Use Ubigi
Ubigi is ideal for: budget-conscious travelers in Europe and Asia who want the best cost per GB, travelers who prioritize speed over app experience, business travelers making regular visits to the same countries (monthly plans), and tech-comfortable users who don't mind a utilitarian app. Less suitable for: travelers who prioritize a polished app experience, users visiting less common destinations outside Europe and Asia, first-time eSIM users who want guided setup assistance, and anyone who needs fast, high-quality customer support.
eSIM OMNI vs Ubigi: Which Is Right for You?
Ubigi and eSIM OMNI compete directly on price in European and Asian markets. For travelers who want maximum savings and are comfortable managing a utilitarian app, Ubigi often wins on raw per-GB pricing. eSIM OMNI offers a more polished experience, clearer plan terms, and more responsive customer support — meaningful advantages for travelers who want setup simplicity and support confidence.

Ubigi Review: Final Verdict
Ubigi is genuinely excellent on the two metrics that matter most for eSIM: price and speed. In Europe and Asia specifically, it's hard to beat. The app is the weak point — functional but frustrating enough that many users cite it as a reason they switched. For tech-comfortable travelers in Europe and Asia who want the cheapest, fastest option and can tolerate a dated interface, Ubigi is outstanding. For those who want the full package — good price, good speed, good app — eSIM OMNI is the stronger overall choice.
