Are SIM cards going extinct? It sure looks that way. Instead of those tiny plastic chips we’ve been using for years, phones are switching to eSIMs—built-in digital SIM cards.
eSIMs are becoming more popular fast. By this year, nearly 40% of smartphones will have them, and by 2030, there could be 7 billion eSIM-connected devices, including tablets, smartwatches, and even smart home gadgets. Big brands like Apple, Samsung, and Google are already on board, with Apple even removing the SIM card slot from the iPhone 15—giving us a clue about where things are heading.
You may ask: why are they changing? The answer is that eSIMs are just easier— you don’t need to swap tiny plastic cards or risk losing them.
As more devices and carriers support eSIMs, those plastic SIM cards might soon be history. But for now, both are still in use, so it’s good to know how they compare.

eSIM vs. Physical SIM: What’s the Difference?
Ever wondered what the difference is between the little plastic SIM cards in your phone and the invisible tech behind eSIMs? Both connect you to your carrier’s network, but eSIMs are more popular. Let’s break down the main difference between physical SIMs and eSIMs.
Physical SIM Cards
A physical SIM (which stands for Subscriber Identity Module) is a small, removable card that stores information needed to connect your phone to a mobile network. It holds your phone number and authentication information to identify you on the network.
SIM cards come in different sizes (standard, micro, and nano) and can be moved between compatible devices. They’re made of plastic with a metal chip and are supported by most carriers and phones.
A physical SIM card, also called a pSIM, is a small, removable card that stores your phone number and network information.
With a physical SIM, you can easily switch devices easily by moving the card, change carriers by swapping it out, and store contacts or data. They’re compatible with most devices and networks, simple to use, and can be removed for security or phone changes. However, they can get lost or damaged, require manual handling, and take up space in your device. If you ever want to switch carriers, you’ll need a new SIM.
While physical SIMs are still common, eSIM technology is more popular now in newer devices.

eSIM: embedded SIM
An eSIM (embedded SIM) is a digital SIM card built directly into your device. It works the same way as a regular SIM but it can be programmed and switched remotely. With an eSIM, you can store multiple eSIM profiles on one device and switch mobile networks easily without needing to swap physical SIM cards. It’s found on smartphones, tablets, smartwatches, and other IoT devices.
eSIM technology uses a special chip called eUICC (embedded Universal Integrated Circuit Card) to store the information needed to connect to a mobile network, much like a regular SIM card but without the need for a physical one. It has a unique identifier and security key that lets it work with compatible devices.
The GSMA, an organization that represents mobile companies, has two versions of the eSIM standard: one for consumer and IoT devices, and another for machine-to-machine (M2M) devices. By February 2025, eSIM has become widely used, with most smartphones made after 2018 supporting it. Almost all mobile carriers are expected to offer eSIM services.
