What is eSIM?

eSIM ( embedded SIM ) is a new technology that replaces the traditional physical SIM card . eSIM is a technology that allows you to use mobile communication services by installing data on your smartphone or tablet instead of a physical SIM card . 


Benefits of using an eSIM when traveling to Portugal

It won't be a burden

The biggest advantage of using an eSIM when traveling to Portugal is that you don't need to carry a separate Wi-Fi router. Also, unlike traditional physical SIM cards that you have to receive and store, eSIMs are installed directly into your device, so you can keep your existing SIM card inserted and use it.

Can be opened immediately at the airport

With an eSIM, you can simply set up your device when you arrive at the airport and start using it right away, saving you time by eliminating the need to purchase or exchange SIM cards locally.

Easy travel to multiple countries

Many travelers from Portugal also visit neighboring European countries such as Spain. If you use an eSIM, you can use it in multiple countries with one eSIM without having to buy a new SIM card every time you cross a border. This allows you to travel smoothly from Portugal to other countries while always having a stable internet connection.

Important points to note about eSIM

Check device compatibility

Not all smartphones and tablets support eSIM . Before using eSIM , it is important to check whether your device supports eSIM . Even if your device supports eSIM , it may not be supported by your carrier or region, so we recommend that you check in advance.

About SIM unlocking

SIM unlocking is also an important point. Normally, devices purchased from a carrier are SIM locked so that only that carrier's SIM card can be used. However, by unlocking the SIM , it becomes possible to use SIM cards or eSIMs from other carriers. When using eSIM , make sure to check whether the device is SIM unlocked. The SIM unlocking procedure can be done by contacting each carrier or consulting the support of the device manufacturer.
