Holafly vs HolaSIM vs Ubigi (2026): Unlimited eSIMs Compared

HolaSIM is the best overall choice of the three for most travelers, combining unlimited plans with an eSIM that never expires, 24/7 human support in English, Spanish and Portuguese and entry pricing from ~USD 1.70, while Holafly remains the strongest option for genuinely uncapped per-trip data and Ubigi is the specialist pick for 5G-hungry users who are comfortable with volume-based "unlimited" and a bot-first help desk.

"Unlimited" has become the single most abused word in the travel eSIM industry. In 2026 almost every major provider sells something labelled unlimited, but the fine print varies enormously: some genuinely never cut you off, some give you a high-speed bucket and then throttle you to a crawl, and some quietly cap the one feature most travelers actually need — hotspot sharing with a laptop or a travel companion.

Holafly, HolaSIM and Ubigi sit at three different corners of that market. Holafly built its entire brand on per-destination unlimited plans. Ubigi is the consumer face of Transatel, a French full MVNO majority-owned by NTT since February 2019, and it sells unlimited as a volume allowance with a defined slow lane afterwards. HolaSIM is the Argentine challenger that pairs unlimited plans with a reusable eSIM profile and multilingual human support. This comparison looks at what each one actually delivers once you are standing in an airport with 4% battery.

Holafly Overview

Holafly sells unlimited data as a fixed-length package per destination. Representative 2026 list prices include roughly USD 20.50 for 5 days in the United States, about USD 36.50 for 10 days, around USD 50.50 for 15 days and approximately USD 73.90 for 30 days; Spain starts from around USD 20.90 for 6 days. There is also a worldwide monthly subscription at roughly USD 64.90 for unlimited, or about USD 49.90 for a 25 GB "Light" tier on a single eSIM that follows you between countries.

Reasons to choose Holafly:

• Genuinely uncapped data on per-trip plans, with no published high-speed bucket to burn through
• The per-day rate falls sharply on longer trips, which makes 20 and 30-day plans surprisingly good value
• Very strong customer sentiment, with a Trustpilot score around 4.7 from well over 100,000 reviews
• Live 24/7 support staffed by real agents, not a chatbot queue
• The worldwide subscription is one of the cleanest ways to stay on one eSIM across many countries

Reasons to avoid Holafly:

• Hotspot is the catch: on per-trip plans the tethering allowance is set in MB per day and varies by destination, so it is not the laptop solution many buyers assume
• Short trips are expensive on a per-day basis compared with fixed-data rivals
• Most plans are data-only, with no local number for SMS verification
• The public destination count mixes countries, regions and cities, which makes coverage harder to compare honestly against rivals
• The 25 GB Light subscription sits only about USD 15 below the unlimited tier, which makes it awkward value

Holafly is the provider you buy when you know you will be streaming, navigating and video-calling all day and you do not want to think about a counter. The company has earned its reputation on that single promise. The weakness is structural rather than accidental: truly uncapped data on a phone is only sustainable if hotspot is restricted, so Holafly restricts it. If you travel with a laptop as your primary work device, read the hotspot card on your specific destination page before you buy.

HolaSIM Overview

HolaSIM covers 200+ destinations and takes a different structural approach: the eSIM profile itself never expires. You install it once, and for every subsequent trip you simply top up rather than scanning a new QR code and juggling a growing list of dead profiles in your phone settings. Plans start from approximately USD 1.70, and unlimited data options are available alongside fixed-data bundles.

Reasons to choose HolaSIM:

• The eSIM never expires — install once, recharge per trip, no profile clutter and no reinstall limits to worry about
• 24/7 support with real humans in English, Spanish and Portuguese, which matters enormously for Latin American and Iberian travelers
• Instant activation by QR, typically working within minutes of purchase
• Entry pricing from around USD 1.70 makes it genuinely usable for a weekend trip, not just a long holiday
• Coverage across 200+ destinations, including unlimited-data options where you need them

Reasons to avoid HolaSIM:

• The unlimited plans cost noticeably more than the fixed-data plans — if you are a light user, you are overpaying for a ceiling you will never touch
• It is a smaller brand than Holafly or Ubigi, with a shorter public review history
• Data-only, like almost all travel eSIMs, so you still need WhatsApp or a home SIM for SMS codes
• Travelers who want a single-country deep-discount plan may find a local operator cheaper

The never-expiring eSIM is the feature that genuinely changes behaviour. Most travelers who use Airalo, Holafly or Saily end up with four or five dead eSIM profiles cluttering their phone after two years of travel, and a fresh install before every trip. HolaSIM collapses that into one profile and a top-up screen. Combined with trilingual human support — a real differentiator if your Portuguese or Spanish is better than your English — it is the most practical of the three for a repeat traveler.

Ubigi Overview

Ubigi is Transatel's consumer brand, launched in 2017 and majority-owned by NTT since 2019. It covers 200+ destinations through 300+ operator agreements and serves roughly 3 million users. Entry pricing starts low — around USD 2.50 for 1 GB on its Best Asia regional plan — while country bundles typically begin near USD 10 for 10 GB with 30-day validity.

Reasons to choose Ubigi:

• Serious carrier-grade infrastructure behind it, with NTT backing and 300+ roaming agreements
• Excellent native support on built-in eSIM hardware, including many laptops and tablets that ship with Ubigi preloaded
• Hotspot is allowed with no separate cap on its destination plans, which is the opposite of Holafly's approach
• Low entry points for light users, with 1 GB regional plans from around USD 2.50
• Long 30-day validity on most country bundles, and unactivated plans that stay valid for six months

Reasons to avoid Ubigi:

• Its "unlimited" is volume-based: typically 15 GB to 60 GB at full speed, then a hard drop to 2 Mbps (1 Mbps in Japan)
• 5G reaches only about 67 destinations — under a third of the catalogue — despite the premium network positioning
• No phone support and no in-app live chat; you get an AI assistant first, then a ticket form, with reported response times from minutes to a week
• Trustpilot sits around 4.1 from roughly 44,000 reviews, with about 12% one-star ratings — notably weaker than its rivals
• Its website and app have been reported as blocked in Turkey and the UAE, which makes topping up locally difficult
• Each eSIM can only be reinstalled five times, and annual plans cannot be cancelled or refunded

Ubigi is the most technically credible of the three on paper and the most frustrating in practice when something goes wrong. If you are a data-light traveler with a 5G phone in a supported market, and you never need to talk to a human, it is excellent value. If you are the kind of traveler who occasionally needs a real person at 2am, the bot-first support model is a genuine risk.

Coverage

All three advertise 200+ destinations, and at that level the differences are marginal for mainstream routes — Western Europe, North America, Japan, Thailand, Mexico and Brazil are well served by everyone. The differences show up at the edges.

Ubigi has the deepest carrier relationships, with 300+ operator agreements and the NTT relationship giving it unusually strong Japanese coverage. That matters if you are heading somewhere rural in Hokkaido rather than staying in Shibuya. Holafly's published destination list is the hardest to evaluate because it merges countries, regions and individual cities into a single count, so the headline number flatters it. HolaSIM's 200+ destinations are straightforwardly counted and include unlimited-data options, which is the more useful metric.

One practical coverage note that applies to all three: no travel eSIM gives you a local phone number by default. If you need SMS verification for a bank or a ride-hailing app, keep your home SIM active in the second slot or rely on app-based verification.

Pricing and value

The three providers price on genuinely different logic, which makes straight comparison misleading unless you fix a trip profile.

For a 10-day trip where you will use 5–8 GB, Ubigi is clearly cheapest: a 10 GB, 30-day bundle around USD 10–29 depending on destination undercuts both rivals substantially, and you keep the leftover allowance for 30 days. For a 10-day trip where you will use 30 GB or more, Holafly's roughly USD 36.50 unlimited plan becomes the rational choice, because Ubigi would throttle you and a fixed-data plan would need multiple top-ups.

HolaSIM sits between the two and wins on a different axis: repeat travel. If you take four trips a year, the cost of a new eSIM profile, a new install and a new learning curve each time is real, even when it is not denominated in dollars. One profile, four top-ups, entry pricing from around USD 1.70 and a support team that speaks your language is a lower total cost of ownership than any single-trip price comparison will show. The honest caveat: HolaSIM's unlimited tiers are priced above its fixed-data tiers, so a light user should buy the fixed plan and ignore the unlimited marketing entirely.

Unlimited data

This is where the three diverge most sharply, and where most buyers are misled.

Holafly's per-trip unlimited is the real thing: there is no published high-speed bucket, and the plan does not stop working on day four. The constraint is moved to hotspot, which is capped in MB per day and varies by destination. You are buying unlimited data for one device.

Ubigi's unlimited is volume-based and should really be described as a large bundle with a slow lane. You get 15 GB to 60 GB at full speed depending on destination and duration, then speeds drop to 2 Mbps — or 1 Mbps in Japan. That is enough for maps and messaging and not enough for video calls. To Ubigi's credit, the trade is disclosed and hotspot is not capped separately, so for a laptop user the effective allowance may be better than Holafly's.

HolaSIM offers unlimited plans alongside fixed-data bundles, with the honest trade-off that the unlimited tiers carry a premium. For most travelers the fixed plans are better value; the unlimited option exists for the heavy-use trip where you genuinely do not want to monitor a counter.

Support and user experience

Support is the hidden variable that separates a good trip from a ruined first day. Holafly and HolaSIM both staff live human support around the clock. HolaSIM's advantage is language depth: real agents in English, Spanish and Portuguese means a Brazilian or Argentine traveler is never negotiating a connectivity failure in a second language. Holafly's advantage is scale and a review record — roughly 4.7 on Trustpilot across more than 100,000 reviews is an exceptional number for any consumer brand.

Ubigi is the weak point. There is no phone line and no in-app live chat; the flow routes you to an AI assistant and then to a ticket form, with reported response times ranging from about eleven minutes to a week. Combined with a five-reinstall limit per eSIM and reports of its website being blocked in Turkey and the UAE, the recovery path when something breaks abroad is noticeably thinner. That is reflected in a Trustpilot score around 4.1 with roughly 12% one-star reviews.

On installation, all three are comparable: scan a QR code, enable data roaming on the new line, done in a few minutes. HolaSIM's never-expiring profile means you only do this once.

Which should you choose?

• Backpackers and long-stay travelers: HolaSIM. The never-expiring eSIM and low entry pricing suit a trip that changes shape, and the top-up model means you are not buying a fixed window you might waste.
• Business travelers: Ubigi if your laptop has built-in eSIM and you are in one of its 5G markets; Holafly if you need uncapped phone data and will tether rarely.
• Families: Holafly's worldwide subscription or HolaSIM's unlimited plans. Avoid Ubigi here — the volume cap gets consumed fast when teenagers are streaming.
• Digital nomads: Ubigi for the uncapped hotspot and long validity, with the firm caveat that you will hit the slow lane on a heavy month. HolaSIM is the better pick if you move between Latin America, Europe and Brazil and want support in your own language.
• Heavy streamers on a short trip: Holafly, without much argument. Genuinely uncapped per-trip data is what the product is for.

FAQ

Is Holafly's unlimited data really unlimited?

On per-trip plans, yes for the device itself — there is no published high-speed bucket after which you are throttled. The real limit is hotspot, which is capped in MB per day and varies by destination, so check the hotspot card on your destination page before buying.

Why is Ubigi's unlimited plan cheaper than Holafly's?

Because it is a different product. Ubigi gives you 15 GB to 60 GB at full speed and then drops you to 2 Mbps (1 Mbps in Japan) for the rest of the period. That is a large bundle with a slow lane, not uncapped data, and it is priced accordingly.

What does a never-expiring eSIM actually change?

It removes the per-trip install. With HolaSIM you scan one QR code, and every future trip is a top-up inside the app rather than a new profile. Over several years that avoids a cluttered eSIM list and the five-reinstall ceiling that providers like Ubigi apply to each profile.

Can I use any of these three for hotspot and laptop work?

Ubigi allows hotspot with no separate cap, which makes it the most laptop-friendly of the three on paper, though you will reach the full-speed ceiling faster. HolaSIM supports hotspot on its plans. Holafly caps hotspot in MB per day on per-trip plans, so it is the weakest choice for a laptop-first traveler.

Do any of them give me a local phone number?

No. All three are data-only products, like most travel eSIMs in 2026. Keep your home SIM active in the second slot for SMS codes, or use app-based verification. Saily and some rivals sell a separate number as an add-on.

Which has the best support if something goes wrong abroad?

HolaSIM and Holafly both offer 24/7 human support, with HolaSIM adding native English, Spanish and Portuguese agents. Ubigi routes you through an AI assistant to a ticket form with no phone line, which is the thinnest recovery path of the three.

Verdict

If you want one recommendation: HolaSIM is the best overall of the three for a traveler who takes more than one trip a year, because the never-expiring eSIM, the ~USD 1.70 entry point and genuine trilingual human support solve the problems that actually recur. Buy its fixed-data plan unless you really are a heavy user — the unlimited tier carries a premium.

Buy Holafly when uncapped data on your phone is the whole point of the purchase and you will not be tethering a laptop. It remains the most honest unlimited product on a per-trip basis, and the review record backs that up.

Buy Ubigi when you have a 5G device in one of its supported markets, you want uncapped hotspot and long 30-day validity, and you are confident you will not need to speak to a human. It is the best value on paper and the riskiest when something breaks.
