Best Unlimited Data eSIM For Travel in 2026 

The best unlimited data eSIM for travel in 2026 is Holafly Plans. They offer an unlimited data subscription that covers 160+ destinations with hotspot, backup data, and 24/7 human support. Unlike competitors, Holafly doesn’t impose a company-level fair usage policy that throttles your speed after a couple of gigabytes per day.

We’ve traveled to over 40 countries since 2018.

Since that time, we’ve tested 12+ travel eSIMs that advertise “unlimited data”.

This includes using eSIMs in places like Bali, Vietnam, the USA, Mexico, and even regional eSIM plans in Europe.

Here’s the problem:

Most unlimited eSIMs aren’t actually unlimited.

Let me explain…

If you check the fine print of most unlimited eSIM providers, you’ll see something called a “fair usage policy”.

And if you read further – it tells you exactly how much “high-speed data” you get before you get throttled.

We’ve been in this exact scenario before.

We were spending the day looking at villas in Bali. That involved a lot of back-and-forth driving, Google Maps, checking websites, watching videos, and the other general daily stuff.

Just after lunch, the data slowed down.

And by slowed down, I mean you couldn’t load a web page or use Google Maps. Even receiving WhatsApp messages seemed like a struggle.

Not a great thing when you’re trying to contact villa owners.

I contacted the provider’s customer support, and they pointed straight to their fair usage policy.

Fast for 2GB per day, then slow for the rest.

So I went looking for a provider that actually delivers unlimited data without strict company-imposed speed caps.

After testing the options, Holafly Plans came out on top.

In this guide, I am going to break down all of the best unlimited data eSIMs for travel, how they compare, and why we ended up choosing Holafly.

The Best Unlimited Data eSIM For Travel

Finding an unlimited data eSIM for travel used to be hard. Now almost every provider has one.

But here’s the thing:

The basic connection is usually the same. Most eSIM providers connect to the same local network providers in each country.

The actual difference comes down to the fine print:

• Data caps
• Fair usage policies
• Throttling speeds
• Customer service
• Extra plan benefits
• What happens when things go wrong

And most importantly…

What kind of deal your provider has negotiated with the local network partners in each destination.

That’s where Holafly Plans stands out.

Below is a comparison of each of the top unlimited data eSIMs for travel:

	Holafly Plans	Saily Ultra	Ubigi World	Airalo Discover
TTA Score	4.8 / 5	4.3 / 5	4.3 / 5	4.0 / 5
Price	$64.90/month	$59.99/month	$140/month	$96.00 for 15 days
Worldwide coverage	160+ destinations	121 destinations	200 destinations	170 destinations
Unlimited data	Yes, no set throttling limit	30GB high-speed, then 1 Mbps	60GB, then 2 Mbps	3GB/day, then 1 Mbps
Company-imposed FUP	No	Yes	Yes	Yes
Monthly subscription	Yes	Yes	Yes (3-month min)	No
Always On (global backup data)	Yes	No	No	No
Hotspot / tethering	Yes	Yes	Yes	Yes
24/7 human support	WhatsApp + Website Chat	In App Chat	Email + AI chatbot	WhatsApp
Trustpilot	Excellent (4.7/5)	Excellent (4.7/5)	Great (4.2/5)	Great (4.0/5)

Table scores and ratings are based on our independent testing and experience with each provider.

Holafly Plans is our top pick for the best unlimited data eSIM for travel.

They’re the only provider on this list without a company-imposed fair usage policy. And they’re the only one that includes Always On backup data.

More on both of those later.

The issue with Saily Ultra is the high-speed data cap. Even on their Premium tier ($59.99/month), you only get 30GB at full speed. After that, everything drops to 1 Mbps.

For a week of heavy use with video calls, maps, and streaming, 30GB goes fast.

Ubigi does offer a World Unlimited plan. But it costs $140 per month with a 3-month minimum commitment. That’s nearly 2x the price of Holafly’s unlimited plan. And you still get throttled to 2 Mbps after 60GB.

Airalo doesn’t offer any worldwide or global unlimited plan that’s more than 15 days. They also enforce a strict 3GB daily fair usage policy.

Go over that, and you’re at 1 Mbps for the rest of the day.

Here’s the bottom line:

If you want one eSIM with unlimited data that works across multiple countries without rebuying, Holafly Plans is the clear unlimited data eSIM choice for travelers.

Why Holafly Plans Wins For Unlimited Data

Holafly Plans is the best unlimited data eSIM because it’s one of the only providers without a company-imposed fair usage policy. 

You also get an eSIM that works in 160+ destinations around the world, and you can cancel anytime.

Here’s what sets it apart from other plans and providers we’ve used. You can also read our full Holafly eSIM review for our complete speed tests and long-term testing results.

Unlimited Data On Every Plan

Every Holafly plan includes unlimited data. No daily caps. No high-speed data limit set by Holafly.

Most competitors put a ceiling on how much high-speed data you actually get. Saily Ultra gives you 30GB before dropping to 1 Mbps. Ubigi caps you at 60GB. Airalo limits you to 3GB per day.

With Holafly, you browse, stream, and video call without watching a data counter.

You also get hotspot sharing, so you can connect your laptop or tablet from the same eSIM.

One eSIM For 160+ Destinations

Holafly Plans covers over 160 destinations with a single eSIM. You don’t buy a new one for every country that you visit.

Here’s why that matters:

If you travel through multiple countries in one trip, most providers make you buy a separate plan for each destination. Simply cross a border, and you’ll need to buy and install a new eSIM plan.

This is one of the reasons we love Holafly Plans.

The moment you land in a new country, your eSIM connects to the local network. Even while you’re taxiing, you’ll be able to connect to the internet.

No need to switch or reinstall a new eSIM profile.

And the best part?

Holafly Plans is a monthly subscription that you can cancel anytime. It’s perfect whether you’re heading overseas on a vacation or doing an extended trip.

Pro Tip: Holafly Plans is great for long layovers. We were recently flying from Thailand to the United States. Our trip included a 12-hour stopover in Singapore. Holafly Plans gives the flexibility to use data in stopover countries without having to buy another eSIM.

Always On Backup Data

Every Holafly plan includes a benefit called Always On.

It gives you 1GB of backup data every month at no extra cost.

Think of it as a safety net.

Keep your eSIM installed even after you cancel your plan, and you’ll automatically receive 1GB of free backup data every month across 160+ destinations.

That’s potentially 12GB of included backup data every year. It resets every 30 days and activates without you doing anything.

Here’s where we found this really helpful…

Let’s say you’re heading home for a couple of weeks between two trips. You forget to reactivate your Holafly plan before you leave your home country.

The Always On backup data is sitting there when you land in your new destination.

That means you’ll be able to order an Uber and get to your new accommodation without any issues.

All you have to do is make sure that you keep your Holafly Plans eSIM installed.

24/7 Human Support

Holafly offers 24/7 human support through WhatsApp and live chat on the website. You message a real person at any time, any day.

That matters more than most people think.

When you’re in a foreign country at 2am with no data connection, you need someone who can actually help. Fast.

Not an AI-powered chatbot or a support ticket that gets answered 5 hours later.

Holafly has a 4.7 out of 5 Excellent rating on Trustpilot from 100,000+ reviews. That tells you something about the quality of their support.

When something goes wrong while traveling, you want a real person on the other end.

Holafly gives you that around the clock.

No Specified Fair Usage Policy

This is the big one.

Every other provider on this list sets their own fair usage policy on high-speed data.

Here’s what I mean:

• Saily Ultra caps high-speed data at 30GB
• Ubigi caps it at 60GB
• Airalo limits you to 3GB per day.

Technically, they’re all still unlimited. But once you use your “high-speed data,” you’re basically unable to use the internet on your phone. We’ve been there before.

Holafly doesn’t set its own artificial cap.

Their official terms state that data speed “may be subject to a network service provider’s fair use policy.” That means any limits come from the local carrier in each country, not from Holafly.

In practice, you typically get far more data before seeing any slowdown depending on the destination.

And even if a local carrier does throttle after heavy use, lighter apps like WhatsApp and Maps tend to keep working.

This is different from most of the major unlimited eSIM providers who set their own artificial limits.

And that’s why Holafly has such a good reputation online.

Which Holafly Plan Should You Choose?

Holafly offers two subscription plans:

• Unlimited – Unlimited Data
• Light – 25GB per month

Both cover 160+ destinations and include Always On backup data.

If you need unlimited data, then the choice is pretty obvious.

But here’s a breakdown of what each plan includes:

	Unlimited Plan	Light Plan
Price	$64.90/month	$49.90/month
Data allowance	Unlimited	25GB
Hotspot	Yes	Yes
Coverage	160+ destinations	160+ destinations
Payment	Monthly	Monthly
Local phone number	Included (US, UK, Canada)	None
Always On	1GB backup	1GB backup
Yearly plan savings	Save 15%	Save 15%

The biggest differences are:

• Data
• Phone number

If you stream, video call, or tether your laptop while traveling, go Unlimited. Using your phone as your main internet connection burns through 25GB faster than you’d expect.

How does the Holafly Plans phone number work?

The Unlimited Plan also includes a US, UK, or Canadian number. It supports inbound SMS and VoIP-based calls, but not traditional cellular calls.

If you’re just traveling for a short period, then you’ll likely keep your own home phone number.

But if you’re traveling for an extended period and need a phone number to receive texts or make VoIP calls, it can be a nice bonus.

Both plans include a hotspot, Always On backup data, and 24/7 support.

What Makes A Good Unlimited Data eSIM?

A good unlimited data eSIM offers truly unlimited data without company-imposed fair usage policies and reliable local network partners.

The best unlimited eSIM also covers multiple countries on a single plan. That way you don’t have to keep installing a new plan every time you change countries.

But that’s not all…

The unique features of the eSIM provider are also important.

Here’s what we look for when evaluating unlimited data eSIMs for travel. And before buying any of them, double-check your device against our eSIM compatible phones list.

Unlimited On Every Plan

A good unlimited data eSIM gives you unlimited data as the standard offering. Not as a premium add-on.

Some providers advertise unlimited data but cap your high-speed usage at 3GB per day or 30GB per month. After that, your connection drops to 1 Mbps or less.

That’s not unlimited. That’s a data plan with a speed limit.

The reality is that every unlimited eSIM provider has a fair usage policy in place. That’s normal, and it’s designed to stop people from taking advantage of the data plan.

What’s not fair is having arbitrary limits set by the provider.

Holafly’s Unlimited Plan gives you unlimited data across all 160+ destinations without a company-set throttling limit.

Coverage Across Borders

A good unlimited data eSIM should cover as many destinations as possible on a single plan. Buying a new eSIM every time you cross a border defeats the purpose.

In 2022, we were on a train from France to Belgium. We just had French-specific eSIMs. The moment we crossed the border into Belgium, the data stopped working.

The issue was that the Wi-Fi on the train was spotty.

I couldn’t buy a new Belgian eSIM until we managed to find a McDonald’s when we reached Bruges. It was painful because we then couldn’t work on the train trip.

The best providers give you one eSIM that works in most destinations around the world. Your connection switches automatically when you land or cross a border.

No extra purchases or hassle required.

It’s a convenience that makes a huge difference when you land in a foreign country you’re not familiar with.

Hotspot And Tethering

Hotspot sharing lets you connect other devices through your eSIM.

This includes:

• Laptop
• Tablet
• Other devices

It essentially turns your phone into a simple Wi-Fi hotspot, giving you more flexibility on the go. As digital nomads, this is an absolute must for us.

Not every eSIM provider includes this. Some block tethering entirely and others restrict it to specific plan tiers.

I cannot tell you how painful it is when you check into a hotel or Airbnb and the Wi-Fi is too slow to do anything. Or you’re stuck at a cafe where the Wi-Fi just doesn’t work.

A good unlimited data eSIM should include hotspot on every plan.

If you’re working from a cafe or your hotel Wi-Fi drops out, tethering your laptop to your phone should be the backup you can count on.

That’s another reason why we like Holafly Plans.

Backup Data When A Plan Ends

Backup data is an extra data allowance that kicks in when you need it.

It acts as a safety net so you’re never completely disconnected while abroad.

Most unlimited eSIM providers don’t offer this. If you pause your plan or it doesn’t renew for some reason, you’re just stuck.

Holafly offers Always On backup data. Every plan includes 1GB of backup data per month, renewed automatically at no extra cost.

It’s there when you need it.

Support That Answers

This is more important than most people think.

Let me explain:

eSIMs sometimes have issues. They don’t install properly or don’t connect to the local network.

If you’ve used as many eSIMs as we have for as long as we have, you will run into a problem at some point. That’s just part of using this technology.

And when something goes wrong…

You want a provider that’s there to help you ASAP.  Not a chatbot or a FAQ page.

A real person who can fix the problem quickly.

My recommendation is to only choose data eSIM providers that offer 24/7 human support. The last thing you want is to land in a new country, have an issue with your eSIM, and not get a support ticket response for 24 hours.

You want it fixed now.

Holafly has a 4.7 out of 5 Excellent rating from over 100,000 reviews, with 24/7 human support via WhatsApp.

That’s the level of support you want when you need it most.

Wrapping It Up

Most eSIMs that say “unlimited” aren’t.

They have a fixed amount of fast-speed data included in the plan. Once you use that data, your speed drops and you’re stuck until your plan renews.

Holafly Plans gives you unlimited data across 160+ destinations on a single eSIM. The plan can be canceled anytime and automatically renews each month.

You also get great benefits such as:

• Hotspot and tethering
• Always On backup data
• 24/7 human support
• Included phone number
• Cancel anytime flexibility
• No company-imposed fair-usage policy

This is why we recommend Holafly Plans so often as the best unlimited data eSIM for travel.

We can’t find another provider that offers the same convenience and benefits all on one eSIM. If you travel full-time, see why Holafly Plans is also our pick for the best eSIM for digital nomads.
