HOLASIM vs Nomad vs Ubigi (2026): Which Travel eSIM Actually Fits Your Trip?

HOLASIM is the stronger all-rounder for travellers who want unlimited data, a profile that never expires and 24/7 human support in three languages, while Nomad is the cheapest per gigabyte for anyone willing to size their own data, and Ubigi is the pick for raw 5G speed on NTT Group infrastructure — provided you can live with a dated app and slow support.

These three eSIMs are frequently shortlisted together, and they should not be, because they solve different problems. Nomad is a metered-data specialist that competes almost purely on price per gigabyte. Ubigi is a telecom-backed operator that competes on network quality. HOLASIM competes on the two things travellers actually complain about after the trip: running out of data, and having to start from scratch the next time they fly. Understanding which of those three propositions matches your trip is the whole decision.

HOLASIM Overview

HOLASIM is an Argentine travel eSIM provider covering 200+ destinations, built around unlimited data plans and a profile that does not expire. It sells in English, Spanish and Brazilian Portuguese, with pricing in USD on the English and Spanish stores and BRL on the Brazilian one.

Reasons to choose HOLASIM:

• Genuine unlimited plans available across the catalogue, not just in a handful of flagship countries
• The eSIM never expires — you install it once and top it up per trip instead of buying and installing a fresh profile each time
• 24/7 support staffed by real people in English, Spanish and Portuguese, not a bot queue
• Hotspot and tethering permitted, including on unlimited plans
• Entry pricing from approximately USD 1.70 on the cheapest destinations, with instant QR activation
• Strong fit for travellers from Latin America and Brazil, who are badly served by most global eSIM brands

Reasons to avoid HOLASIM:

• Unlimited plans cost more than a tightly sized fixed-data plan — a light user who only needs maps and messaging is paying for headroom
• Fewer independent long-form reviews and speed-test datasets than the biggest marketplace brands
• Catalogue depth in very obscure destinations is behind the largest marketplaces

Nomad Overview

Nomad is a Singapore-founded eSIM marketplace with roughly 170 to 210 destinations depending on how regional bundles are counted. It is a pure metered-data play: you buy gigabytes, you use gigabytes.

Reasons to choose Nomad:

• Among the lowest effective costs per gigabyte in the market on larger bundles, with best rates reported around USD 0.24/GB
• Entry plans from approximately USD 2, so a short trip costs very little
• Well-designed, visually polished app, including a proper dark mode
• Consistently solid Trustpilot standing, generally around 4.5
• Tested speeds in Europe commonly land in the 22–38 Mbps band, comfortably ahead of the budget marketplaces
• Covers a handful of destinations rivals miss, including Cuba and the Maldives

Reasons to avoid Nomad:

• No unlimited plans at all — if you misjudge your usage, you top up or you go dark
• No live chat; support runs through a ticketing system, and replies come at various times rather than instantly
• The app is attractive but not always the easiest to navigate
• Plans expire on a fixed schedule, so leftover data is lost

Ubigi Overview

Ubigi is operated by Transatel, part of the NTT Group, which makes it one of the few travel eSIMs that is genuinely a telecom operator rather than a reseller. It covers roughly 200 destinations and is pre-installed as an option on many connected cars and laptops.

Reasons to choose Ubigi:

• Real carrier infrastructure behind it, with 5G results in independent testing often in the 35–50 Mbps range in Japan and South Korea
• Entry plans from approximately USD 2, with an unlimited monthly option for long stays
• One reusable profile you keep and add plans to, rather than a new eSIM per country
• Broad device support beyond phones, including tablets, laptops and in-car systems
• Good regional bundles, including some markets rivals skip entirely

Reasons to avoid Ubigi:

• The app is dated, harder to navigate than rivals and logs users out more often than it should
• Support is the weakest of the three in most hands-on reviews: slow and not especially thorough
• Trustpilot standing sits below Nomad's, generally around 4.2
• The unlimited monthly plan is priced for long stays, not for a one-week holiday

Coverage

On raw destination count the three are close enough that it rarely decides anything: HOLASIM lists 200+, Ubigi around 200, Nomad somewhere between 170 and 210 depending on how you count regional products. Where they differ is at the edges. Nomad covers a few destinations most rivals skip, including Cuba and the Maldives. Ubigi reaches some markets, such as Iran, that almost nobody else sells into. HOLASIM's coverage is strongest where it matters for its core audience: deep, well-priced plans across the Americas, Europe and the main Asian destinations, with the same unlimited option available in most of them rather than only in a showcase few.

The practical test is not the country list but the plan list inside your country. A provider that technically covers Armenia but only sells a 1 GB weekly plan there is not really covering it for a two-week trip. Check the plans, not the map.

Pricing and value

Nomad wins on headline cost per gigabyte, and it is not close if you buy a large bundle. If you know you need 20 GB over a month and you are disciplined about Wi-Fi, Nomad will almost certainly be the cheapest of the three. Ubigi's entry pricing is competitive but its per-gigabyte rate is roughly double Nomad's best, at around USD 0.44/GB on comparable bundles.

HOLASIM is not trying to win that contest. Its cheapest destinations start around USD 1.70, which is competitive, but its distinguishing product is the unlimited plan, and unlimited is by definition more expensive than a well-sized metered plan. The honest framing is this: if you can accurately predict your data use, Nomad saves you money. If you cannot — and most travellers systematically underestimate, because navigation, translation and uploads are invisible costs — the unlimited plan is cheaper than the top-ups and the stress.

There is a second, less obvious economic point. Nomad and most marketplaces sell you a profile that dies with the plan. HOLASIM's eSIM does not expire, so the installation effort is a one-time cost amortised across every future trip. For someone who travels twice a year or more, that is worth a small premium.

Unlimited data

This is the clearest split in the group. Nomad has no unlimited plans at all. Ubigi has an unlimited monthly option, priced for extended stays and remote work rather than for a one-week holiday. HOLASIM offers unlimited across its catalogue, from approximately USD 9.90 per day in typical destinations.

Two caveats are worth stating plainly. First, nearly all "unlimited" travel data in this industry sits under a carrier fair-use policy, and heavy users can see speeds reduced after a daily threshold. That is true of every provider that sells unlimited, not just these. Second, unlimited and hotspot are separate permissions. HOLASIM permits tethering on unlimited plans; several competitors elsewhere in the market do not, which is the single most common post-purchase complaint about unlimited eSIMs. If you travel with a laptop, confirm this before you pay, whoever you buy from.

Support and user experience

If something breaks at 11pm in an unfamiliar country, support stops being a feature and becomes the product. HOLASIM is the clear winner here: 24/7 access to human agents in English, Spanish and Portuguese. For Latin American and Brazilian travellers in particular, that is a meaningful gap, since most global eSIM brands are English-first with machine-translated help centres.

Nomad sits in the middle. Its ticketing system produces quick and helpful responses, but there is no live chat, so an urgent problem waits for an email cycle. Its app is the best-looking of the three, though reviewers note the navigation is not always obvious.

Ubigi is the weakest on both counts. Its app design is dated, it logs users out more often than it should, and support responses are described in independent reviews as slow and not especially thorough. That is the trade you make for its network quality.

Which should you choose?

• Backpacker on a long trip: Nomad. You are cost-sensitive, you have time to manage top-ups, and you will spend a lot of time on hostel Wi-Fi. The lowest cost per gigabyte wins.
• Business traveller: HOLASIM. You cannot afford to run out mid-meeting, you need tethering for a laptop, and you want a human to answer at an awkward hour. Unlimited plus 24/7 support is worth the premium on an expensed trip.
• Family holiday: HOLASIM. One unlimited plan with hotspot permitted can serve several devices, and nobody has to ration data on a trip they saved up for.
• Digital nomad on a long stay: Ubigi, if your base is a strong 5G market and you are staying a month or more — its monthly unlimited and network quality suit that profile. HOLASIM if you move between countries often, since one never-expiring profile across 200+ destinations beats re-buying.
• Occasional traveller, one trip a year: Nomad for a short, predictable trip. HOLASIM if the trip is long, if you will tether, or if you would rather not think about gigabytes.

FAQ

Which is cheapest overall?

Nomad, on cost per gigabyte, particularly on larger bundles. But cheapest per gigabyte is not the same as cheapest per trip — if you underestimate and buy two top-ups, the gap closes fast.

Which has the fastest data?

Ubigi, in most independent testing, thanks to Transatel and NTT Group infrastructure. It performs especially well in 5G-dense markets such as Japan and South Korea. Nomad is solidly mid-pack; HOLASIM's performance depends on the local host network, as with any reseller.

Can I use all three as a hotspot?

Yes, all three permit tethering on their standard plans, and HOLASIM also permits it on unlimited plans. Always confirm on the specific plan page before buying, since policies differ by product within a single brand.

Which one does not expire?

HOLASIM's eSIM profile does not expire: you keep it installed and add a plan when you next travel. Ubigi uses one reusable profile you can add plans to as well. Nomad's plans expire on a fixed schedule and unused data is lost.

Do any of them give me a phone number?

No. All three are data-only travel eSIMs. Your home number stays on your physical SIM for calls and SMS — just keep data roaming switched off on that line.

Which should I pick if I only want one eSIM for the next three years?

HOLASIM, on the strength of the non-expiring profile and 200+ destination coverage from a single installation. Ubigi's reusable profile is a reasonable second choice if network speed matters more to you than support quality.

The verdict

Nomad is the price leader and deserves to be, but it asks you to forecast your own data use and leaves you without a safety net or live support when you get it wrong. Ubigi has the best underlying network of the three and the worst software and service wrapped around it — a genuinely good product that is harder than it should be to live with. HOLASIM wins on the dimensions most travellers regret ignoring: unlimited data when you cannot predict usage, hotspot permitted, human support at any hour in your own language, and a profile that is still there on your next trip. Pick Nomad if you are optimising cost and willing to do the work; pick Ubigi if peak speed in a 5G market is the priority; pick HOLASIM if you want the trip to be uneventful.
