If you're tired of dealing with physical SIM cards, changing them every time you travel, or losing coverage at the worst possible moment, eSIM technology is here to simplify your life. It's not just a passing fad: it's the future of mobile connectivity, and more and more smartphones are incorporating it to offer you greater freedom and flexibility.
What exactly is an eSIM?
An eSIM (or embedded SIM) is a digital SIM card that's built into your phone's hardware. Unlike traditional SIM cards, you don't need a physical card to insert or remove. Everything is managed electronically, downloading carrier profiles directly to your device.
This means you can activate a phone line without going to a physical store, without waiting for a card to arrive in the mail, and without worrying about losing or breaking a tiny piece of plastic.
eSIM technology is certified by the GSMA (the global association of mobile operators) and is already supported by hundreds of operators in more than 190 countries. Its adoption is growing rapidly because it offers real advantages for both users and manufacturers.
Key advantages of having an eSIM in your mobile phone
Instant operator switch
Forget about going to physical stores or waiting for deliveries. With eSIM, you can switch carriers in minutes by scanning a QR code or downloading an app. It's especially useful if you're not happy with your current carrier or find a better deal.
Ideal for travelers
This is probably the most valued advantage. When you travel abroad, you can get a temporary local plan without having to buy a physical SIM at the airport. You save on roaming charges, have coverage from the moment you land, and can compare rates online before making your decision.
The Xplore 2, For example, it allows you to keep your regular line active and add a local eSIM for data, managing both from the phone settings.
Multiple lines on a single device
With eSIM you can have multiple active lines simultaneously: one personal and one professional, or one national and one international. You don't need to carry two phones or keep swapping physical SIM cards.
Many models, such as the Xplore 2, They support dual SIM (one physical + one eSIM), giving you complete flexibility to choose how you organize your lines.
More space for other technologies
Removing the SIM card tray allows manufacturers to use that internal space for other improvements: larger batteries, better cooling systems, or additional components. While it may seem like a minor detail, every millimeter counts in the design of a modern smartphone.
Enhanced security
An eSIM cannot be physically removed, making it difficult for someone to steal your phone and swap the SIM to resell it or access your accounts. Furthermore, in case of loss or theft, you can remotely deactivate the eSIM without needing to physically recover the device.
Sustainability
By eliminating plastic SIM cards and their packaging, eSIM technology helps reduce waste. It may seem insignificant, but when you add up millions of devices worldwide, the positive environmental impact is considerable.
Our personal opinion
When I traveled to Switzerland, I got an eSIM so I wouldn't be charged for data there, but I lost my physical SIM card. I got home and had to go to the carrier (assuming the store was open, of course) and request a new one. So complicated! With this, I could have easily forgotten about it and saved myself the trouble. Just one small example of the advantages of an eSIM.
Frequently Asked Questions
Do all carriers offer eSIM?
Not all, but more and more. In Spain, operators like Movistar, Vodafone, Orange, and Yoigo already support eSIM. It's advisable to check with your operator before buying a phone with eSIM only.
Can I go back to using a physical SIM if I have an eSIM?
Yes, especially on phones like the Xplore 2 that support dual SIM. You can use both technologies simultaneously without any problems.
Is it complicated to set up an eSIM?
Not at all. You usually scan a QR code provided by your carrier, and the profile is installed automatically in seconds. It's even easier than inserting a physical card.
What happens if I change my mobile phone?
You can transfer your eSIM to the new device. The process varies depending on the carrier, but it's usually as simple as deactivating it on the old phone and activating it on the new one using a QR code or app.
Does the eSIM consume more battery?
No. Battery consumption is virtually identical to that of a physical SIM. Electronic profile management does not add significant load to the system.
Is the eSIM secure?
Yes, even more so than a physical SIM. Because it's integrated into the hardware, it can't be removed by a thief, and you can deactivate it remotely if you lose your phone.
