What is a physical SIM?

A physical SIM is a small card that is inserted into a cellular device, such as a smartphone or tablet, to connect to a cellular network, along with talk time and data services. The physical SIM contains identification and authentication information that allows the cellular network to recognize the device and the user. The information is stored on a microchip inside the card and is protected with a PIN code to prevent unauthorized access.
One of the main advantages of a physical SIM is its wide availability and compatibility with most cellular devices around the world. Physical SIM cards are easy to purchase and you can find them at electronics stores, cellular network operators, and online. In addition, they offer a variety of data and voice plans that can fit your needs easily.
However, there are several disadvantages. One of these is that the process of buying and activating them can be tiresome and slow. Also, if you travel frequently, changing your SIM card from one country to another can be a problem. Another disadvantage is that the physical SIM card is subject to damage, theft, or loss. Certainly, this can result in the loss of data stored on the card and the need to replace it.
What is an eSIM?

eSIM is a new digital SIM tech that eliminates the need for a physical card to connect to cellular networks. Instead of a physical SIM card, identification, and authentication information is stored on a chip embedded in the cellular device. An eSIM allows users to download cellular network operator profiles directly to the device and switch between them without having to physically change the SIM card.
One of the main advantages of eSIM vs. SIM is its convenience. The setup of the eSIM is very simple. Also, users can change cellular network operators without having to physically change the SIM card and without having to wait for a new SIM card to arrive. Additionally, the eSIM has no risk of damage, theft, or loss, which means that the data stored on it is protected and safe. However, one of the downsides to the eSIM is that it is not yet widely available on all cellular devices and in all countries.
For those interested in eSIM, a suitable option is the Holafly store. This provider offers eSIMs for various destinations around the world. By choosing Holafly, travelers can save time and money by avoiding international roaming costs and having the flexibility to select a custom voice and data plans.
Why is the eSIM vs SIM better?

The eSIM offers several benefits over traditional physical SIM cards. Firstly, eSIM is much more convenient for users. Why? Because it eliminates the need to physically change the SIM card when changing cellular network operators. Instead, users can download cellular network operator profiles directly to their devices and switch between them with just a few clicks!
Another advantage of the eSIM is its flexibility. Users can switch cellular network operators at any time, allowing them to select the voice and data plan that best suits their needs and budget. In addition, the eSIM has no risk of damage, theft, or loss, which means that the data stored on it is protected and safe.
While eSIM offers many interesting advantages, there are also some disadvantages that users should consider before making the switch. In some cases, the data and voice plans available through the eSIM may be more expensive than the plans available through a physical SIM card. Also, the eSIM is not available on all cellular devices and in all countries yet. This can indeed limit its usefulness for some people.
How to activate an eSIM?
Activating an eSIM is a relatively simple process. First, users need to make sure that their cellular device supports eSIM. They will then need to get the cellular network operator profile they wish to use, which you can download directly to the device via a special app or a QR code provided by the operator.
Once users download the profile from their cellular network provider, they must follow the steps provided by the operator to activate the eSIM on their cellular device. This may include inserting an activation key or confirming activation via text message once the QR code is scanned.
Compared to activating a physical SIM card, activating an eSIM can be faster and easier. With a physical SIM card, users must insert the card into the device, wait for it to activate, and set up the cellular network operator profile through the device’s settings menu.
What is eSIM vs SIM-compatible devices?
More and more cellular devices offer eSIM compatibility. Among the most popular devices that support eSIM are the latest iPhone models, Samsung Galaxy, Google Pixel, and the Apple Watch and Samsung Galaxy Watch smartwatches.
Compared to devices that only support a physical SIM card, the list of eSIM-compatible devices is still relatively limited. But it should continue to grow as more manufacturers jump on the bandwagon.
Do you want to know the complete list of eSIM-compatible devices? We recommend visiting the manufacturer’s or cellular network operator’s website. You can also find an up-to-date list of eSIM-compatible devices here.

The steps to change the operator with an eSIM vary depending on the device and the cellular network provider. However, the steps include downloading a new eSIM from the desired network carrier.
