Comparing eSIM and Physical SIM: What You Need to Know
Change language:
Having access to the internet when travelling is of crucial importance, whether it’s for having directions at hand, being able to call the local primary care service when needed, or checking the most important sightseeing points in the city you’re in, a stable internet connection is non-negotiable. However, you are met with two options when it comes to SIM cards you can use abroad. In addition to physical SIM cards, eSIM has recently become increasingly popular. In this article, we will compare the most important aspects of eSIMs and physical SIM cards in hopes that you will have an easier time choosing what works best for you.
eSIM vs physical SIM: form factor

Let’s first look at the forms of these two different types of SIMs. The physical SIM is a small, removable chip that needs to be inserted into your phone or other device. It’s available in different sizes (nano, micro, standard). The eSIM (which is available for tourism and business travels for multiple countries at Yesim.app) is embedded directly into your device’s hardware (it has no removable part). You activate it digitally via a QR code or app, eliminating the need for a physical card.

Convenience
Another important factor is convenience, and this battle has a clear winner. A physical SIM card requires manual insertion or removal. If you’re switching carriers or phones, you need to physically swap SIM cards. However, an eSIM (available in Hungarian on Yesim.app) is more convenient for switching between carriers, numbers, or plans, as everything is done digitally. This is particularly helpful when travelling or switching between personal and business numbers.
Device compatibility
Almost every phone supports physical SIMs, though new devices are increasingly supporting eSIM technology. However, not all devices support eSIM, but many modern smartphones (like the iPhone, Pixel, and Samsung Galaxy) have started integrating eSIM functionality. Make sure your phone is compatible before relying on this option!
