📶 Why I recommend preparing internet before travelling

One of the things I most recommend preparing before a trip is your internet connection. Being able to use Google Maps, book transport, search for a restaurant, translate something or message home as soon as you land gives a lot of peace of mind.

That is why my recommendation for travelling is to use an eSIM.

❓ What is an eSIM?

An eSIM is a digital SIM card. You do not need to change the physical SIM in your phone or buy one when you arrive. You simply buy your plan online, install the eSIM on your phone and activate mobile data when you reach your destination.

It is a very convenient option if you want internet during your trip without depending on hotel, airport or cafe Wi-Fi.

✨ My recommendation: Holafly

The travel eSIM I recommend is Holafly, because it is easy to buy, install and use. You can also prepare it before the trip and activate it when you arrive.

⬇️ How to install your Holafly eSIM

You do not download it like a normal app. Instead, you install an eSIM profile on your phone. I recommend doing it before your trip, calmly from home, with a good Wi-Fi connection.

If you have an iPhone

Open your iPhone settings.
Go to “Mobile Data” or “Cellular”.
Tap “Add eSIM”.
Select “Use QR Code”.
Scan the QR code sent by Holafly.
Follow the on-screen steps.
Give it an easy name, such as “Holafly trip”.

If you have Android

Open your phone settings.
Go to “Connections”.
Select “SIM manager”.
Tap “Add eSIM”.
Scan the Holafly QR code.
Follow the installation steps.
Save it with a clear name, such as “Holafly trip”.

🛬 How to use the eSIM when you arrive

Open your phone settings.
Activate the Holafly eSIM line.
Select the Holafly eSIM as your mobile data line.
Turn on data roaming for the eSIM.
Turn off mobile data on your regular SIM if you want to avoid roaming charges.
Turn off Wi-Fi and check that internet works.

After that, you can use mobile internet during your trip for maps, social media, WhatsApp, bookings, translations and anything else you need.

✅ Tips before travelling with an eSIM

Install the eSIM before the trip. Activate it when you arrive. Use a stable Wi-Fi connection for setup. Save the Holafly email with the QR code. Have the QR code on another device or printed. Check that your phone is compatible. Do not delete the eSIM during the trip unless needed. Check data roaming if it does not work at first.

🌍 Is travelling with an eSIM worth it?

For me, yes. It is a very convenient way to have internet from the first moment of your trip, without looking for phone shops, changing physical SIM cards or depending on Wi-Fi.
