Are you planning your next trip and looking for a way to stay connected to the internet?

By the time you finish, you will know what an eSIM is and how it can provide you with instant internet access, whether you're backpacking through Europe, exploring Asian markets, or relaxing on tropical beaches.

What is an eSIM, and how does it work?

eSIM is an easier & faster solution for all travellers to stay connected anywhere they go.

If you have ever travelled to foreign countries, you probably have experienced the situation of searching for local SIMs. And it´s not always fun nor 100% reliable.

The eSIM technology eliminates that need and enables users to change mobile operators without the need to buy a new card and physically swap SIMs from their device.  You can switch between mobile operators in seconds.

 

How does an eSIM work?

eSIM runs on programmable chips that are built into your phone. It all lies down to the embedded universal integrated circuit card (Euicc), which powers eSIM functionality.

Basically, it means you can activate and use all the features by entering or scanning the code into your phone, rather than changing the physical card in it. They work just like traditional SIM cards but run completely through software and remote programming.

All the data needed for switching between mobile operators is stored digitally. You can think of it as a digital SIM card installed on the phone, tablet, smartwatch or other smart device.

 

Who is eSIM for?

Whether you're a frequent flyer, vacation traveller, digital nomad, or business professional, the eSIM solution keeps you connected worldwide.

That is why our GigaXeSIM was created specifically for global explorers, the ones who stay connected wherever they go.

 

How to check if your phone supports eSIM and activate it?

Before you buy the eSIM, find the answer to the big question. Can you use eSIM on your phone?

It´s easy to check if your current phone supports eSIM. Follow these few steps or try to type "eSIM" in Settings / Search.

 

1. Settings ­> Mobile Data / SIM cards and mobile networks.

If you see “Add eSIM”, your phone supports it, and you are ready.

 

      2. Carrier network unlocked:

Go to Settings ­> General>About. Check that “Carrier Lock” shows “No restrictions”.

 

     3. Compatibility:

Go to Connections / Network & Internet ­> Sim Card Manager.

If you see an eSIM section or “Add eSIM” option, your device is compatible.

 

If you did all the checkups, you are ready for the purchase. Select the eSIM plan that best suits your needs and activate it.

Can I have both an eSIM and a physical SIM?

Yes, you can have both, but make sure to switch profiles and deactivate the ones you are not using at the time. You can store both SIM and eSIM profiles on most modern devices, but typically only one stays active at a time.

 

What to do if my phone doesn´t support eSIM?

We are aware that not all phones support eSIM. However, that does not exclude you from having access to the same service—the internet—while on the road.

For this reason, GigaX offers physical eSIM. It works like a regular SIM card and can be reused for future trips.

So, don´t worry, the stories from that European trip will be published, your mom will know you are safe, and you can continue working on that work project. Even if eSIM is not supported by your phone.

eSIM technology - your gateway to effortless global connectivity 

eSIMs allow easier switching between mobile carriers, support multiple profiles on one device, and free up space within phones, leading to more compact designs. Although the technology is relatively new (from around 2012), some resources predict it will completely take over the market within a few years.

Traditional SIM cards won´t just perish, but starting from 2027, more than 80% of devices will have eSIM technology.

So, in the end, what is an eSIM exactly? It´s the future of seamless connectivity in your pocket.
