Holafly eSIM: complete guide to unlimited data abroad, installation and tips
What an eSIM is, how Holafly works, unlimited data in 175+ destinations, Holafly Plans, hotspot, phone compatibility, step-by-step installation, prices, limitations and comparison with Yesim and Roamic.
Arriving in another country and having internet from the first minute is no longer a luxury. eSIMs let you activate a data plan on your phone without changing the physical SIM card, and Holafly is one of the best-known brands in this market thanks to its unlimited data in more than one hundred and seventy-five destinations. In this guide we explain what an eSIM is, how Holafly works, how to install it, what to check before buying and how to make the most of it during your trip.
What an eSIM is and why it changes how you travel
An eSIM is a SIM card built into the phone and programmed digitally. Instead of buying a physical card at the airport or paying your carrier's roaming, you buy a plan online, scan a QR code and your phone connects to a local network at the destination. You can keep your usual SIM active for calls and texts and use the eSIM only for data.
For travelers, the advantages are clear: no hunting for shops on arrival, no high roaming charges and internet as soon as the plane lands.
What Holafly is
Holafly is a travel eSIM provider known for offering unlimited data. It covers more than one hundred and seventy-five destinations in Europe, the Americas, Africa, Asia and Oceania, with plans by country and by region. Activation is by QR code, and on regional plans the phone switches networks automatically when crossing borders.
In our network we recommend Holafly through the CoVisas link, and the brand often offers discounts with promo codes for new customers.
Unlimited data: what it means in practice
Holafly's main difference from many competitors is that it sells unlimited data plans instead of gigabyte packages. For a traveler who uses maps, social media, video calls and cloud work, not having to watch consumption is a big advantage. Before buying, check the fair use policy and speed conditions of the chosen plan, because each provider defines how it manages traffic.
Holafly Plans: the monthly subscription
Besides plans by number of days, Holafly offers Holafly Plans, a monthly subscription designed for frequent travelers and nomads. It's billed monthly and can be paused, resumed or canceled at any time from the app or website. We have a dedicated guide to this option.
Sharing data (hotspot)
The conditions for sharing data with other devices vary by plan and have changed over time. Some sources indicate certain plans don't allow hotspot use. If you need to connect your laptop or a companion's phone, check the plan's current conditions before buying or consider an eSIM that allows hotspot, such as Yesim or Roamic.
Phone compatibility
Not every phone supports eSIM. Recent models from the main brands are usually compatible, but check in your phone's settings or the provider's compatibility list. The phone must also be unlocked, meaning not carrier-locked. If your phone isn't compatible, a local physical SIM is the alternative.
How to install Holafly step by step
- Buy the plan for your destination from the link in this guide.
- You'll receive an email with the QR code and instructions.
- On wifi, go to your phone's settings and choose to add a mobile data plan or eSIM.
- Scan the QR code and follow the prompts.
- Label the eSIM with a name such as "Travel" to tell it apart from your usual line.
- On arrival, enable the eSIM for data and turn on data roaming for that line.
- Turn off data on your usual SIM to avoid roaming charges.
When to install it
It's best to install it before the trip, with a good connection, but activate it on arrival, following the provider's instructions. That way you avoid installation problems at the airport and don't use up plan days early.
Prices
Prices depend on destination and duration. Published sources mention plans from around twenty-nine euros, although prices change often and with promotions. Always compare the price with your expected usage: if you use the internet heavily, an unlimited plan may work out cheaper than buying several data packages.

Benefits in practice
For a business traveler, internet from landing means ordering a ride, answering emails and arriving at the meeting on time. For a family, it means using maps and translators and calling travel insurance assistance if someone gets sick. For a nomad, it means working from anywhere without depending on the accommodation's wifi.
Holafly and travel insurance
One detail many travelers forget: to use travel insurance assistance you need to communicate, and many assistance companies work through WhatsApp or apps. An eSIM active from landing ensures you can ask for help at any time. That's why we recommend sorting connectivity together with insurance, with options such as IATI, Assist 365, GO! Assistance, Protege tu Viaje or Globely.
Limitations to keep in mind
- Data only: the eSIM doesn't include a local number for traditional calls.
- Hotspot: check the plan's conditions.
- Entry price: some competitors offer cheaper small packages.
- Compatibility: you need an unlocked, eSIM-compatible phone.
Holafly compared with other eSIMs in our network
Yesim offers local, regional, global and pay-as-you-go plans in more than one hundred and eighty-five destinations, with hotspot allowed. Roamic has very cheap plans, from €0.99 for one gigabyte for seven days in several European countries, and also allows hotspot. Holafly stands out for unlimited data and its monthly subscription. If you need to share data with your laptop, Yesim or Roamic may fit better; if you want to stop worrying about consumption, Holafly.
Common mistakes
Installing the eSIM without wifi. You need a connection to download the profile.
Deleting the eSIM by mistake. In many cases the same QR can't be reinstalled.
Forgetting to turn off roaming on your usual SIM. You may get charges from your carrier.
Not checking compatibility. Check before buying.
Assuming you can share data. Check the hotspot conditions.
Tips for multi-country trips
If you're visiting several countries, a regional plan avoids buying an eSIM for each destination and allows automatic network switching. Check that every country on your itinerary is included in the regional plan. For trips combining regions, such as Europe and Asia, compare a global plan with two regional plans.
Data usage: how much you really consume
To choose well, it helps to know your consumption. Browsing social media, using maps and sending messages use relatively little; video calls, video streaming and uploading high-resolution photos use much more. A traveler working remotely with daily video calls can use several gigabytes a day. With an unlimited plan you don't need to calculate it, but if you choose a gigabyte-based plan from another provider, check your usual consumption in your phone's settings before traveling.
Security and public wifi
Having your own mobile data reduces the need for public wifi in airports, cafés and hotels, networks that can be unsafe for banking or entering passwords. With an eSIM you can make payments, check your bank or manage travel documents with more peace of mind.
What to do if the eSIM won't connect
If the eSIM doesn't connect on arrival, check that it's enabled as the data line, that data roaming is on for that line and that airplane mode is off. Restart the phone. If the problem persists, contact support from the app or website using airport wifi. Most connection problems are solved with these steps.
Holafly when you land in a new country
For tourists and nomads arriving in any country, an eSIM with data from landing makes it easy to use ride apps at the airport, contact your accommodation and find your way around the city. If you'll stay for several months, compare the eSIM with a prepaid plan from a local carrier, which may be cheaper for long stays.
eSIM vs local physical SIM vs roaming
There are three main ways to get data abroad. Your carrier's roaming is convenient because you don't have to do anything, but it's usually expensive and sometimes limited. A local physical SIM is usually cheap for long stays, but requires finding a shop, showing your passport and swapping the card, which can be awkward on arrival. An eSIM combines convenience and a reasonable price: you buy it before traveling, install it in minutes and it works from landing.
For short and medium trips, an eSIM is usually the best option. For stays of several months in one country, it's worth comparing with a local plan.
Traveling with children or teenagers
If your children have phones, think about whether they need their own data or whether sharing from an adult's phone is enough. If the plan doesn't allow data sharing, each phone will need its own eSIM. Set up parental controls and explain how to reach you if they get separated from the group.
Business trips: a productivity argument
For a business traveler, time is money. Having data as soon as you switch on your phone after landing lets you confirm transport, check schedule changes and answer urgent messages while waiting for your bags. Many companies reimburse connectivity costs, so keep the eSIM invoice.
Discounts and codes
Holafly often offers discounts with promo codes. Check whether a promotion is running before paying; the link in this guide is our partner link.
Support during the trip
If you have a problem with the eSIM, contact support from the app or website. Have your purchase email and phone model at hand to speed up help.
How to choose between a country plan and a regional plan
If your trip is in a single country, a local plan is usually the most precise option. If you're visiting several countries in the same region, such as Europe or Southeast Asia, a regional plan avoids buying several eSIMs and changing settings at every border. Before deciding, list the countries on your itinerary, including long layovers, and check that they're all in the regional plan.
Keep a backup plan
Even the best eSIM can occasionally fail to connect in a remote area or during a network outage. Note down the wifi details of your accommodation, keep your usual SIM's roaming as a last-resort option and save offline maps of the cities you'll visit. A small backup plan means a connection hiccup never turns into a real problem.
Checklist before you travel
- Compatible, unlocked phone.
- Plan bought for the destination or region.
- eSIM installed on wifi.
