HOLASIM vs KnowRoaming (2026): Which Travel eSIM Wins?

HOLASIM wins for travelers who want a reusable eSIM profile and real human support in English, Spanish or Portuguese, while KnowRoaming wins for anyone who wants one global unlimited plan across 164 destinations with a clearly published daily speed cap.

These two providers sit on different sides of a philosophical split in the travel eSIM market. KnowRoaming, a Toronto-born brand that has been in international connectivity since the sticker-SIM era, sells coverage breadth: one global plan, one price, 164 destinations. HOLASIM, an Argentine company serving travelers across the Americas and Europe, sells permanence and service: a profile that stays on your phone forever and a support team of actual people who answer in your language at any hour.

Both are data-only. Neither gives you a local phone number. The question is which model fits the way you travel.

HOLASIM Overview

HOLASIM covers 200+ destinations with plans starting from around USD 1.70, and it offers genuinely unlimited tiers alongside fixed-data ones. The defining feature is that the eSIM profile never expires: you install it once, and every subsequent trip is a top-up rather than a fresh QR code and a new line cluttering your settings.

Reasons to choose HOLASIM:

• The eSIM profile never expires — install once, recharge for each trip
• 24/7 support staffed by humans in English, Spanish and Portuguese
• Genuinely unlimited plans without a hard daily throttle headline
• Coverage across 200+ destinations from a single profile
• Instant QR activation, so you land connected
• Entry prices from around USD 1.70 on its cheapest destinations

Reasons to avoid HOLASIM:

• Unlimited plans cost more than fixed-data plans, including its own
• Per-destination pricing varies widely — some countries start well above the headline entry price
• Smaller brand footprint than the global incumbents, with fewer third-party reviews to check
• Data only, with no calls or SMS on a local number

KnowRoaming Overview

KnowRoaming sells global, regional and country plans, with the global catalog reaching 164 destinations and the overall network touching more than 200. Its global unlimited runs from around USD 11.99 for three days to USD 99.99 for thirty, with 90- and 180-day options for long-haul travelers. Fixed global data starts at about USD 6.50 for 1 GB over seven days.

Reasons to choose KnowRoaming:

• One global plan covering 164 destinations, ideal for multi-country trips
• Clearly published unlimited policy: 2 GB a day at full speed, then up to 256 kbps, resetting every 24 hours
• Hotspot included on every plan, fixed or unlimited
• 5G in most supported countries, LTE elsewhere
• Long-duration options up to 180 days that most rivals do not sell
• A 25% discount for Visa cardholders, usable up to six times a year
• Trustpilot score of about 4.1 out of 5

Reasons to avoid KnowRoaming:

• The "unlimited" plan is really 2 GB a day — heavy users will hit 256 kbps by afternoon
• Plans must be activated within 90 days of purchase, and unused data does not roll over
• 30-day plans are expensive relative to the category; reviewers have flagged this repeatedly
• Support runs through WhatsApp and a web form, with reports of AI agents closing tickets unresolved
• No 1-day plans, so short stopovers mean buying a week

Coverage

On raw numbers the two are close. KnowRoaming's global plan reaches 164 destinations and its broader network claims more than 200; HOLASIM also covers 200+. For almost any mainstream itinerary — Europe, North and South America, East and Southeast Asia, the Gulf — both will work.

The difference is in the shape of the catalog. KnowRoaming leans harder into regional packages, including underserved areas such as East Africa, West Africa and Oceania, which is genuinely useful if your route includes places most travel eSIMs price badly or skip. HOLASIM's strength lies in the Americas and Europe, where its Spanish- and Portuguese-language operation is built around the way travelers from Argentina, Brazil, Mexico and Spain actually move.

Neither provider publishes a complete list of local roaming partners per country, which is normal for the category but worth noting: you are buying a coverage promise, not a named network.

Pricing and value

KnowRoaming's global unlimited ladder is transparent and easy to compare: roughly USD 11.99 for 3 days, 17.99 for 5, 35.00 for 10, 55.00 for 15, 68.99 for 20 and 99.99 for 30. Its fixed global plans run about USD 6.50 for 1 GB over 7 days, 16.00 for 3 GB, 22.00 for 5 GB, 37.00 for 10 GB and 60.00 for 20 GB.

Those long plans are where reviewers push back. A 30-day global unlimited at USD 99.99 is a real sum, and TechRadar's review noted that KnowRoaming's monthly country plans are often beaten on price by smaller rivals. The Visa cardholder discount of 25%, usable up to six times a year, materially changes that arithmetic if you qualify — a 30-day global unlimited drops to around USD 75.

HOLASIM starts lower, from roughly USD 1.70 on its cheapest destinations, but its per-country pricing varies more. For a short trip to a well-covered market, HOLASIM will usually undercut KnowRoaming's global plan outright. For a six-country trip in a single month, KnowRoaming's single global plan can be the cheaper and simpler purchase than stitching together multiple regional ones.

The honest summary: KnowRoaming wins on simplicity across many countries, HOLASIM wins on single-destination value and on what the profile is worth to you over multiple trips.

Unlimited data

This is the most important section for most buyers, and the two providers handle it differently.

KnowRoaming is admirably explicit: unlimited means 2 GB per day at full speed, then up to 256 kbps, with the allowance resetting every 24 hours from the plan's start. That is enough for maps, messaging, social scrolling and a moderate amount of video. It is not enough to tether a laptop through a working day, and Trustpilot reviewers have complained about the drop being severe — one said they could not send email after the cap hit. The honesty is worth crediting; plenty of competitors bury the same limit in a fair-usage clause. But a disclosed cap is still a cap.

HOLASIM's unlimited tiers do not lead with a published daily throttle figure, which is a point in their favor for heavy users but also means you should confirm the current fair-usage terms for your destination before buying. HOLASIM is also upfront that its unlimited plans cost more than its fixed-data ones — if your consumption is genuinely modest, you are better off on a capped plan from either provider.

Support and user experience

KnowRoaming holds a Trustpilot score of around 4.1 out of 5 from roughly 89 reviews, which is respectable but a thin sample. The praise is consistent: easy setup, reliable connectivity, cheaper than carrier roaming. The complaints cluster around two things — the severity of the post-2 GB throttle, and support. Reviewers report that WhatsApp support is handled by an AI agent that closes conversations without resolving the issue, and TechRadar separately noted there is no phone or email channel and that the web form is slow. KnowRoaming does reply to negative reviews, which counts for something.

HOLASIM's differentiator is precisely here: 24/7 support with human agents in English, Spanish and Portuguese. If you have ever stood in an arrivals hall at midnight with a profile that will not activate, you know what that is worth. For travelers from Latin America and Brazil especially, being able to describe a technical problem in your own language rather than through translated English is not a small thing.

Installation is comparable on both: QR code or app, a few minutes over Wi-Fi before departure. KnowRoaming has a documented quirk where some Android users need to set the APN to "globaldata" manually.

Which should you choose?

• Backpacker crossing many borders: KnowRoaming. One global plan across 164 destinations beats buying a new eSIM at every frontier, and its regional packs cover places others price badly.
• Business traveler: HOLASIM, if you need a laptop tethered through a full working day — KnowRoaming's 2 GB daily cap will bite by mid-afternoon. KnowRoaming, if your usage is phone-centric and you want one invoice for a multi-country trip.
• Family trip: HOLASIM. The never-expiring profile means you set up each family member's phone once rather than redoing it annually, and multilingual support helps when the person with the problem is not the person who bought the plan.
• Digital nomad: Split decision. KnowRoaming's 90- and 180-day plans are genuinely rare and useful for long stays. But if you are working from the connection, budget for the throttle or choose HOLASIM's unlimited instead.
• Spanish- or Portuguese-speaking traveler: HOLASIM, on support alone.
• Short stopover: HOLASIM. KnowRoaming sells no 1-day plan, so a 14-hour layover costs you a week.

FAQ

Is KnowRoaming's unlimited data really unlimited?

No, and the company says so plainly. You get 2 GB per day at full speed, then speeds drop to as low as 256 kbps until the allowance resets 24 hours later. That is a usable fallback for messaging and maps but not for video calls or tethering.

Does the HOLASIM eSIM really never expire?

The profile itself stays installed on your phone indefinitely. Individual data plans still have their own validity, but you recharge the same profile rather than installing a new eSIM for each trip.

Which is cheaper, HOLASIM or KnowRoaming?

For a single destination over a short trip, HOLASIM usually comes out ahead, with entry prices from around USD 1.70. For a multi-country trip in one month, KnowRoaming's single global plan can be cheaper than buying several separate ones. If you hold a Visa card, KnowRoaming's 25% discount narrows the gap considerably.

Can I use either eSIM as a mobile hotspot?

Yes, both support tethering on all plans. Remember that on KnowRoaming, hotspot traffic counts toward the 2 GB daily full-speed allowance, so sharing with several devices will exhaust it quickly.

Do either of them offer phone calls or SMS?

Neither provides a local number for calls or texts. Both are data-only. Keep your home SIM active to receive SMS verification codes, and use WhatsApp, Telegram or FaceTime for calls.

How long do I have to activate a KnowRoaming plan after buying it?

Your plan must be started within 90 days of purchase, and it begins when you connect in a supported country. Unused data expires at the end of the plan and does not carry over.

The verdict

KnowRoaming is a solid, transparent operator with an unusually honest unlimited policy and a global catalog that handles multi-country itineraries better than most. Its weak points are real: expensive long plans, no 1-day option, and support that too often routes travelers to an AI agent.

HOLASIM is the better pick for most travelers reading this in Spanish or Portuguese, for anyone who tethers a laptop daily, and for anyone who values a profile they install once and keep. Its unlimited plans cost more than fixed-data alternatives, and that is a fair trade only if you actually use the data.

Choose KnowRoaming for breadth across borders. Choose HOLASIM for permanence, heavy use and a human on the other end of the chat.
