HOLASIM vs Numero eSIM (2026): Which Travel eSIM Is Better?

If you want data that simply works abroad, HOLASIM is the better buy — a lower entry price, genuinely unlimited plans and a profile that never expires. Numero eSIM only makes sense if you specifically need a virtual phone number alongside your data, and even then its public review record deserves a hard look before you pay.

These two providers are rarely compared, because they are not really chasing the same customer. HOLASIM is a travel data company: one profile, 200+ destinations, unlimited options, humans on support. Numero eSIM is a telephony company that also sells data: its headline product is a virtual phone number you can keep for years, with travel data plans sold alongside it. Both are legitimate things to want. The question is which one is right for your trip, and that depends almost entirely on whether you need a number or just need internet.

HOLASIM Overview

HOLASIM is an Argentine company selling prepaid travel eSIMs across more than 200 destinations, with a catalogue that spans small daily bundles, large fixed-data packages and fully unlimited plans. Its two structural differences from most of the market are unlimited data as a first-class product rather than a throttled gimmick, and a profile that does not expire — you install the eSIM once, and recharge the same profile for your next trip instead of buying and installing a new one.

Reasons to choose HOLASIM:

• Entry pricing from around USD 1.70, among the lowest in the travel eSIM market
• Genuinely unlimited plans, not "unlimited after throttling to 128 kbps"
• The eSIM never expires: install once, top it up for every future trip
• 24/7 support staffed by real people in English, Spanish and Portuguese
• Instant QR activation, so you can be online minutes after landing
• Coverage across 200+ destinations on a single profile

Reasons to avoid HOLASIM:

• Unlimited plans cost noticeably more than a small fixed-data bundle — if you genuinely use 1 GB a week, you are overpaying for headroom you will not touch
• Data-only: no phone number, no inbound SMS, no voice minutes
• Smaller brand footprint in the US and UK than Airalo or Holafly, so fewer third-party reviews to read
• Pricing is shown in USD on the English and Spanish stores and in BRL on the Brazilian store, which means you need to compare in the currency you will actually be charged in

Numero eSIM Overview

Numero eSIM, run by Numero (numeroesim.com), is built around virtual phone numbers. You buy a second number in another country, keep it as long as you keep paying, and use it for calls, SMS and app verification. Alongside that, it sells local, regional and global travel data eSIMs, plus "Full eSIM" products that combine data with calling. Its own site cites 200+ destinations in body copy and 190+ countries in its metadata; the independent catalogue at eSIMDB lists its global plans as covering 116 countries, so treat the marketing figure with some caution.

Reasons to choose Numero eSIM:

• The only provider in this comparison that sells a real phone number — useful for app verification, local callbacks and long-stay relocations
• Combined data-and-calls products for travellers who need both on one profile
• Mature native apps on iOS and Android, with account management in one place
• Advertised 24/7 support with a claimed six-minute average response time
• Global plans with long validity windows, including a 20 GB plan valid for 180 days

Reasons to avoid Numero eSIM:

• Its public review record is the single biggest concern: as of late 2026, Trustpilot shows no TrustScore for numeroesim.com, with a notice that the rating is unavailable due to a breach of Trustpilot's guidelines and that fake reviews were removed. Of 481 reviews, roughly 46% are five-star and 49% are one-star — a polarised distribution that is worth reading in full before you buy
• Recurring complaints in those reviews about activation failures, refused or delayed refunds, and accounts closed without explanation
• Its travel data plans are data-only, like everyone else's — the phone number is a separate purchase, which is easy to miss
• No unlimited option in the independently listed global catalogue, despite the site referring to "select unlimited data options"
• Higher entry price than HOLASIM for the equivalent small plan

Coverage

On paper the two are close. HOLASIM publishes 200+ destinations on a single profile. Numero's own pages claim between 190 and 200+, but the independent listing at eSIMDB puts its global plan at 116 countries, which is a meaningful gap between marketing and verified catalogue.

In practice, coverage counts matter less than you would think, because nearly every travel eSIM resells capacity from the same handful of wholesale aggregators. What actually differs is which local partner network you land on in a given country, and neither provider publishes that per plan. If the network matters to you — say you know one operator has far better rural coverage in your destination — you will get more transparency from Airalo, which names carriers on some plans, than from either of these two.

Where HOLASIM has a practical edge is the single-profile model. Because the profile does not expire and covers 200+ destinations, a frequent traveller ends up with one eSIM line on their phone rather than a graveyard of dead profiles from past trips. That is an underrated quality-of-life difference on iPhones, which cap how many eSIMs you can store.

Pricing and value

HOLASIM starts at roughly USD 1.70 depending on destination and plan length. Numero's cheapest independently listed global plan is 1 GB for 7 days at about USD 7.81, scaling to 3 GB/30 days at ~USD 20.08, 5 GB/30 days at ~USD 27.89, 10 GB/90 days at ~USD 52.43 and 20 GB/180 days at ~USD 83.67.

Those Numero numbers are not bad for global plans — a 20 GB bundle valid for six months across 100+ countries is a genuinely useful product for someone travelling continuously. The per-gigabyte cost on that tier works out around USD 4.18, which is mid-market. But the comparison is not apples to apples: HOLASIM's cheap entry pricing is for single-destination plans, which is what most travellers actually buy. If you are going to Italy for ten days, a local HOLASIM plan will be dramatically cheaper than a global Numero bundle, and you will not be paying for coverage in 100 countries you are not visiting.

The honest version: Numero wins on long-validity global bundles for perpetual travellers. HOLASIM wins on everything else, which is most trips.

Unlimited data

This is the clearest split. HOLASIM sells unlimited as a real product, and it is the main reason to pick it over a cheaper fixed-data competitor. For destinations like the US, Spain or Brazil, an unlimited plan means you stop thinking about data — maps running all day, video calls home, tethering a laptop in a café, uploading photos without counting megabytes.

Numero's independently listed global catalogue has no unlimited tier, though its own site refers to "select unlimited data options" without specifying where. If unlimited data is what you came for, HOLASIM is the straightforward answer and Numero is not a contender.

The counterargument, which we will make on HOLASIM's behalf and against it: unlimited costs more. A traveller who spends a week on hotel Wi-Fi and uses maps for twenty minutes a day will spend less on a 1 GB plan from almost anyone. Buy unlimited for the freedom, not because it is cheaper — it usually is not.

Support and user experience

HOLASIM's pitch is humans, 24/7, in three languages. For Spanish and Portuguese speakers that is a real differentiator, because most of this market defaults to English-first chat support with slow ticket queues. Activation is QR-based and immediate.

Numero has the better app. Native iOS and Android clients, with numbers, data plans and calling in one interface, is a genuinely nicer experience than managing an eSIM through a web account — and if you hold a virtual number long-term, you need that app anyway.

But the user experience question for Numero cannot stop at the app. Its Trustpilot page currently carries no score at all, with Trustpilot stating that the rating is unavailable due to a breach of its guidelines and that it removed fake reviews from the company's profile. The 481 reviews that remain split almost evenly between five stars and one star, with the negative reviews clustering on activation failures, refunds that were refused or took months, and accounts closed without a stated reason. A polarised distribution is not proof of bad service — plenty of telecom companies attract angry reviews — but a suspended rating and removed fake reviews is a signal you should weigh before handing over payment details, especially for a recurring virtual-number subscription.

Which should you choose?

• Backpackers and budget travellers: HOLASIM. Lower entry price, single-destination plans that match how you travel, and no subscription to cancel later.
• Business travellers: HOLASIM for data reliability and 24/7 human support when something fails before a meeting. Consider Numero only if you need a local number clients can call.
• Families: HOLASIM. Unlimited on the parent phone with tethering for everyone else is simpler and cheaper than multiple data bundles, and the never-expiring profile survives until the next holiday.
• Digital nomads: The one case where it is genuinely close. If you move constantly and want a stable number for banking and app verification, Numero's number plus a long global bundle is a coherent setup. If you mainly need lots of data in a few countries at a time, HOLASIM's unlimited plans are better value.
• Anyone who needs inbound SMS or app verification codes: Numero, because HOLASIM is data-only and cannot do this. Just go in with your eyes open on the reputation issue, and pay with a method that lets you dispute a charge.

FAQ

Does HOLASIM give you a phone number?

No. HOLASIM eSIMs are data-only. You keep your home SIM active for calls and SMS, and use WhatsApp, FaceTime or Signal over the data line. If you need a second real number, that is exactly the gap Numero fills.

Is Numero eSIM safe to use?

It is a functioning, long-running service with apps on both major stores, and many users report no problems. The caution is specific and public: Trustpilot has suspended its rating over a guidelines breach and removed fake reviews, and about half the remaining reviews are one-star. Read the recent reviews yourself, start with a small plan rather than a long subscription, and pay with a card or platform that offers chargebacks.

Which is cheaper for a two-week trip to one country?

HOLASIM, in most cases. A single-destination plan avoids paying for global coverage you will not use. Numero becomes competitive only when you need many countries over several months on one bundle.

Can I use the hotspot with either provider?

Neither publishes tethering rules clearly on a per-plan basis, so check the terms for the specific plan before buying. As a general rule, fixed-data plans allow tethering more often than unlimited ones, because unlimited plans are where providers worry about abuse.

Do these eSIMs work on my phone?

Both need an eSIM-capable, carrier-unlocked handset — broadly iPhone XR or newer, Pixel 3 or newer, Galaxy S20 or newer. Dial *#06# and look for an EID to confirm.

What happens to my plan when I come home?

With HOLASIM the profile stays on your phone indefinitely and you recharge it for the next trip. With Numero, a data plan expires at the end of its validity window; a virtual number continues only while you keep paying for it, which is a recurring charge to remember.

The verdict: HOLASIM is the better travel eSIM for almost everyone, because it is cheaper to start, it sells unlimited data properly, it does not make you reinstall a profile every trip, and support answers in three languages at any hour. Numero eSIM is a different product wearing similar clothes — buy it for the virtual phone number, not for the data, and do your own reading on its review history before you commit to anything recurring.
