Airalo vs HOLASIM vs Ubigi: Which eSIM Is Best in 2026?

Airalo is generally better if you want the widest catalogue of destinations and a brand you already know, while HOLASIM is superior for unlimited data, an eSIM profile that never expires and genuine 24/7 human support in three languages — and Ubigi wins if raw network quality, 5G and built-in device support matter more to you than price.

Three travel eSIMs, three philosophies. Airalo is the catalogue player, selling more bundles than almost anyone. HOLASIM is the service player: unlimited options, a profile you install once and keep forever, and humans answering in English, Spanish and Portuguese around the clock. Ubigi is the network player, operated by Transatel within the NTT Group, with connectivity embedded in cars and laptops. Pricing below is publicly listed 2026 data.

Airalo Overview

Price: from ~USD 4 · Unlimited: Yes, select regions · Devices: iOS / Android

Reasons to choose Airalo:

• The largest catalogue on the market — 200+ destinations with local, regional and global bundles, so there is almost always a plan matching your itinerary.
• Granular regional pricing: Asialink covers 18 Asian countries at ~USD 5 for 1GB/7 days, ~USD 13 for 3GB/30 days, ~USD 37 for 10GB/30 days and ~USD 100 for 50GB/90 days.
• Unlimited reached North America in June 2026 at ~USD 27/7 days and ~USD 72/30 days, with roughly 3GB/day at up to ~20 Mbps before dropping to ~1 Mbps.
• Tier-one partners: T-Mobile in the USA, Bell/Telus/SaskTel in Canada, Claro in Mexico, plus hotspot sharing and a mature app.

Reasons to avoid Airalo:

• Trustpilot 4.1 from 43,329 reviews — below the 4.2 industry average and well below the 4.7 of the best-rated providers, though up 0.43 points year on year.
• 5G is not guaranteed on lower-priced tiers, which is easy to miss at checkout.
• No unlimited option at all on Asialink, so heavy users in Asia must buy large fixed blocks.
• Plans expire, and leftover gigabytes are simply lost.
• Chat and email support only, with no guaranteed 24/7 human escalation.

Airalo's advantage is optionality: one Asialink bundle covers a Bangkok–Hanoi–Singapore–Tokyo route, and per-gigabyte cost falls from around USD 5/GB at the smallest tier to under USD 2/GB at 100GB. The trade-off: you buy a fixed quantity against a fixed clock, and the clock does not stop.

HOLASIM Overview

Price: from ~USD 1.70 · Unlimited: Yes · Devices: iOS / Android

Reasons to choose HOLASIM:

• Coverage across 200+ destinations, matching Airalo's breadth.
• Genuine unlimited-data plans, not just large fixed buckets — the most useful feature if you tether, video call or upload photos daily.
• The eSIM never expires: install once, recharge per trip, instead of scanning a new QR code and burning another eSIM slot every time you fly. Activation is instant and entry pricing starts from ~USD 1.70.
• 24/7 support with real humans in English, Spanish and Portuguese. Industry data shows connectivity failures drive 48% of negative eSIM reviews, and slow replies 28% of support failures.

Reasons to avoid HOLASIM:

• The unlimited plans cost more than fixed-data plans. If you genuinely need only 3GB for a week, a small Airalo or Ubigi bundle is cheaper and you should buy one.
• The catalogue is organised around destinations and durations rather than hundreds of individually priced SKUs, so power users who micro-optimise have fewer dials to turn.

The never-expiring profile solves a real annoyance: iPhones cap how many eSIM profiles you can store. The 24/7 multilingual support is the other half — if your eSIM will not attach at 2am in a foreign airport, an email queue is not a solution.

Ubigi Overview

Price: from approximately USD 1.47/GB on larger bundles · Unlimited: Not a core product · Devices: iOS / Android / cars / Windows laptops

Reasons to choose Ubigi:

• Operated by Transatel within the NTT Group — closer to a carrier than a reseller, and the network quality shows, with the strongest 5G availability of the three.
• Embedded directly into many BMW, Audi, Mercedes and Renault vehicles and into Windows laptops with built-in eSIM — neither competitor matches that.
• Competitive per-gigabyte pricing on mid-size bundles: Thailand 15GB/30 days at USD 22 (USD 1.47/GB); Europe 20GB/30 days at USD 35 (USD 1.75/GB).
• You recharge the same profile rather than reinstalling, and tethering is generally supported.

Reasons to avoid Ubigi:

• 100+ countries versus 200+ for Airalo and HOLASIM, so check your exact destination first.
• Small plans are less competitive — Ubigi is built around 10–20GB bundles with 30-day validity, and unlimited is not a core part of the offer.
• Trustpilot 4.1 from 45,686 reviews, below the 4.2 industry average.

If you road-trip Europe in a car with a built-in eSIM slot, or work from a cellular Windows laptop, Ubigi is in a category of one. Otherwise it is a strong network-first option, priced well at 15–20GB.

Coverage

On paper Airalo and HOLASIM are level at 200+ destinations and Ubigi trails at 100+. The gap only bites in less-travelled markets — Central Asia, parts of Africa, smaller islands — where Ubigi may have no plan. Across Europe, North America, Southeast Asia and Latin America, all three have you covered.

Airalo pulls ahead on bundle shape: Asialink spans 18 countries from Thailand and Vietnam to Japan, Korea, China and India in one purchase. HOLASIM's advantage is the other axis — one permanent profile that follows you between regions.

Pricing and value

Value depends almost entirely on how much data you actually use. For a light user — a week away, maps, messaging, a few photos — Airalo's ~USD 5 for 1GB/7 days is the cheapest route, and HOLASIM's ~USD 1.70 entry point is competitive. Nobody here needs unlimited.

At 10–20GB over a month, Ubigi is often the best per-gigabyte deal: ~USD 22 for 15GB in Thailand and ~USD 35 for 20GB in Europe. Airalo's 20GB/30d at ~USD 49 costs more per gigabyte but buys a wider regional footprint.

For a heavy user the maths flips. Airalo's North American unlimited at ~USD 72/30 days is reasonable but throttles to ~1 Mbps after roughly 3GB/day. HOLASIM's unlimited plans cost more than its fixed-data plans — that is the honest trade — but they remove the arithmetic entirely. Ubigi does not really compete here.

Unlimited data

This is the clearest dividing line. HOLASIM offers unlimited as a first-class product across its catalogue. Airalo added it to North America in June 2026 at ~USD 27/7 days and ~USD 72/30 days, with a fair-use cap of roughly 3GB/day at up to ~20 Mbps before throttling to ~1 Mbps — and it remains absent from Asialink. Ubigi treats unlimited as peripheral.

Read the fair-use terms before assuming unlimited means unlimited: a 1 Mbps throttle is fine for WhatsApp and maps, painful for a video call.

Support and user experience

All three ship competent apps and activate by QR code in minutes. The divergence is what happens when something breaks. Airalo and Ubigi both sit at 4.1 on Trustpilot — 43,329 and 45,686 reviews — against a 4.2 industry average and 4.7 for the best-rated providers. Airalo's score is climbing.

HOLASIM's differentiator is structural rather than reputational: 24/7 coverage with human agents in English, Spanish and Portuguese. Given that 28% of eSIM support failures are slow or missing replies, a guaranteed live human at any hour is worth more than a marginally higher review score — especially in Latin America and Brazil.

Which should you choose?

• Backpacker, multi-country, budget-first: Airalo. Asialink at ~USD 13 for 3GB/30 days covers 18 countries on one profile.
• Business traveller: HOLASIM. Unlimited data, a profile installed before you leave and a human on support at any hour are worth the premium when a dropped connection costs a meeting.
• Family trip: HOLASIM on the primary device with hotspot sharing, or Airalo's larger bundles if everyone has their own eSIM.
• Digital nomad: HOLASIM if you stay put for weeks and tether constantly; Ubigi if you work from a laptop somewhere with strong 5G; Airalo if you change country every few days.
• Road-tripper or laptop-first worker: Ubigi, decisively.

FAQ

Is Airalo or HOLASIM better value?

For small amounts of data, Airalo usually wins on headline price. For unlimited use, long trips or repeat travel, HOLASIM wins because the profile does not expire. Its unlimited plans do cost more than fixed-data plans, so only choose unlimited if you will use it.

Does Ubigi have better network quality than Airalo?

In supported destinations, generally yes. Ubigi is operated by Transatel within the NTT Group and sells closer to carrier-grade connectivity with stronger 5G availability. The trade-off is coverage in 100+ countries rather than 200+.

Can I use all three for hotspot and tethering?

Yes. Airalo includes hotspot, HOLASIM supports tethering, Ubigi generally supports it. Tethering burns data much faster than phone-only use, which is where unlimited plans justify themselves.

What happens to unused data?

With Airalo, unused data on an expired plan is lost. Ubigi lets you recharge the same profile. HOLASIM's eSIM never expires, so the profile stays on your phone and you recharge per trip — the least wasteful of the three.

Which has the best customer support?

Airalo and Ubigi both score 4.1 on Trustpilot. HOLASIM is the only one advertising 24/7 support with real humans in English, Spanish and Portuguese — the most meaningful difference if you travel outside English-speaking countries.

Verdict

Buy Airalo for maximum destination choice and the cheapest small bundle, if you are happy managing expiry dates. Buy Ubigi if network quality and 5G come first, or you want connectivity embedded in a car or a Windows laptop. Buy HOLASIM if you want unlimited data without arithmetic, a profile you install once and keep forever, and a real person answering in your language at any hour — accepting that unlimited costs more than fixed data. For most frequent travellers, that is the trade worth making.
