What is an unlimited data eSIM and how does it work?

If you’ve never used one, an eSIM (or virtual SIM card) is a technology already built into your smartphone. You don’t need to open your phone’s SIM tray to insert a card to get internet access abroad like in the past. You simply buy an eSIM plan online, install it, and that’s it: your phone connects to the local networks of your destination country.

What is an eSIM and how does it work?

When it comes to an unlimited data eSIM, the magic is even better. As the name suggests, it ensures you don’t have to worry about data limits or extra roaming fees. You can browse as much as you want, post that Instagram story, or use your GPS without holding back.

However, it is worth pointing out that it is not all perfect. Even though there are no limits and you won’t face exorbitant costs at the end of the month, the quality of your internet connection varies depending on your location, and after using a certain amount of data, your speed will drop.

Fox’s tip

Install your eSIM while you still have a stable Wi-Fi connection in your home country. You can set everything up and keep the plan turned off. As soon as your plane lands at your destination, simply activate the line in your phone’s settings. Here is how to install your Airalo eSIM.
