Is Holafly The Best eSIM For Travellers? Review And Discount Code

Staying connected while travelling has changed dramatically for me over the past few years. Thankfully, the days of swapping out my physical SIM card at every new destination or paying extortionate international roaming fees are no longer my only options.

The rise of eSIM technology has completely transformed my approach to using mobile data abroad. Among the growing number of providers, Holafly has become my favourite because it offers me simplicity, speed, and reliable connectivity wherever I go.

Holafly caters to all kinds of travellers—from solo backpackers exploring Southeast Asia, business travellers meeting in different countries, families on European road trips, to digital nomads working their way across continents. The convenience of unlimited data at my fingertips and global coverage make it one of the best options for me to stay connected abroad without stress.

After testing Holafly's eSIMs on several of my trips, I can vouch for their reliability. My research led me to Holafly as the best eSIM for unlimited data options, a straightforward setup, and coverage in over 200 destinations worldwide, and it does what it says on the tin. It's designed for people like me who want their phone to work seamlessly when they arrive—no hidden promises, no tech jargon, and no complicated settings.

In this Holafly review, I'll share how the eSIM works, how it compares to another popular provider, and why Holafly is consistently ranked among the best eSIM providers for international travellers. And you can also get a discount with my code WHEREANGIEWANDERS on any purchase.

Who Is Holafly?

First things first—let's deep-dive into who Holafly are.

Holafly was founded in 2017 by two frequent travellers who were frustrated by high roaming charges and the frustration of physical SIMs on their trips. Holafly quickly established itself as one of the most trusted global eSIM providers. Its mission is simple: to keep travellers connected wherever they go, without the stress of roaming fees, unreliable local SIMs, or complicated setup processes.

Holafly has its headquarters in Dublin, Ireland, with offices in other places around the world.

Holafly's eSIMs have been used by over 10 million travellers worldwide, covering more than 200 destinations, from major travel hubs like Europe and the USA to remote islands and exotic corners of Southeast Asia.

Unlike traditional SIM cards, Holafly's eSIMs are 100% digital. Once purchased, simply scan a QR code, install the eSIM, and enable it on arrival—you're instantly connected. There's no need to wait for physical delivery or hunt down a local SIM provider.

But what really sets Holafly apart is its unlimited data in most destinations, letting you travel without worrying about running out of data for maps, messages, or uploads. Perfect for me as a travel blogger and content creator.

Is Holafly right for my data and budget needs?

If, like me, you use a moderate to heavy amount of data when you travel, the peace of mind of unlimited data outweighs the financial and network drawbacks of using a provider with caps or limits.

How to order and install a Holafly eSIM on your phone

Once I had established that Holafly was the best eSIM for my needs, ordering one was easy. The entire process took just a few minutes. It was perfect for me, and it will be perfect for last-minute planners or travellers who realise they forgot to sort mobile data before travelling.

Here's how it works:

1. Visit Holafly's website: Receive 5% off your eSIM purchase with code WHEREANGIEWANDERS.
2. Find your ideal eSIM: Choose the destination you want to go to—specific city, country, region, or even a global eSIM—and the number of days you need, which can be personalised from 1 to 90 days across over 200 destinations.
3. Purchase: Holafly will send the QR code and other setup instructions to the email address or WhatsApp number registered at checkout.
4. Scan to install: Go to your Settings > Mobile Data > Add eSIM. On your phone, scan the QR code and follow the screen instructions. Once installed, you can enable your new eSIM upon arrival at your destination. You can also install it manually, or, for iPhone users with iOS 17.4 or later, there is a one-button install option.
5. Stay connected: That's it! You're online from the moment you arrive.

Holafly subscription plans

My experience with the Holafly eSIM was focused on a regional eSIM for Asia; however, for travellers intending to use an eSIM for an extended period, there is an option to subscribe to a Holafly Plan on a monthly basis.

Holafly Plans cover 160+ countries, with 2 options: light with 25GB per month, or unlimited, which, of course, includes unlimited data and even unlimited hotspot. It is also important to note that both subscriptions can be cancelled at any time.

Holafly vs Airalo: Key Differences

When comparing Holafly to one of the biggest names in the eSIM space, Airalo, several key distinctions set Holafly apart — especially for heavy data users who prioritise simplicity, unlimited data, and stress-free connectivity.

While I haven't used Airalo myself, I researched it while looking for the best eSIM data plans for my needs and found that Holafly was my best option as an eSIM provider for Asia. I was able to purchase unlimited data for the duration of my trips, whereas Airalo does not offer unlimited data on its regional Asia plan.

Why do these differences matter for travellers?

• Unlimited Data = Peace of Mind
• For me, Holafly's unlimited data wins over Airalo's per-GB plans. This means no stressful data monitoring or throttled speeds mid-trip. I can stream, navigate, and upload without restrictions.
• Regional Bundles That Make Sense
• Instead of fixed "Europe" or "Asia" bundles that include countries I may never visit, Holafly's eSIMs target the destinations I need.

Pros and Cons of Holafly eSIM

What Worked For Me

• Unlimited data in over 200 destinations.
• Instant activation with QR code.
• No need to swap out physical SIMs or visit stores.
• Works on most iPhones, Samsung, and Google Pixel devices.
• Hotspot sharing is supported (great for families or digital nomads who occasionally need connectivity).
• 24/7 live chat support (multilingual).

What Could Be Improved

• No local phone number—though some European eSIM providers include a local number, most, including Holafly, are data-only. However, in 6 weeks of travelling through Asia, this did not cause any issues for me.
• Not the cheapest eSIM for light data users looking for ultra-budget options—travellers who use only a little data might prefer capped, pay-per-GB plans, although Holafly's unlimited data removes any data anxiety, and for me it's worth paying slightly more for peace of mind.

Is Holafly the Best eSIM for International Travellers?

Holafly isn't just another eSIM provider — it’s the kind of travel essential that quietly does its job, letting you focus on the journey, not your data. For me, Holafly is the best eSIM for heavy data users like me, making staying connected easier than ever.
