Out with the Old, In with the New? — Physical SIM vs. eSIM comparison

4 min readSep 23


The traditional physical SIM card has long been the standard way of connecting our smartphones to cellular networks. But increasingly, a new technology called the eSIM (embedded SIM) threatens to replace the need for a physical SIM altogether. What are the key differences between these two SIM options? Which one is better for today’s mobile users?

Out with the Old, In with the New? — Physical SIM vs. eSIM comparison

Before diving into the key differences, let’s briefly define what exactly physical SIM cards and eSIMs are.

  • A physical SIM card is the traditional removable smart card that goes into your smartphone, containing your subscription details to connect to a mobile network.
  • An eSIM on the other hand, is an embedded digital SIM chip that is permanently installed in your device. eSIM profiles are stored on the chip and can be remotely provisioned and activated with cellular plans, without the need for a physical card. Companies like Uquid are on the leading edge, providing eSIM data plans that work globally in over 200 countries (including very hot countries in the trend of using eSIM such as Australia, Japan, India, USA…etc). You can purchase eSIM service from Uquid’s digital store and conveniently connect without swapping out cards.

To understand this SIM card showdown, let’s examine how physical SIMs and eSIMs compare across some key categories:


For many years, physical SIM cards have allowed users to easily swap between carriers and plans by simply replacing the card. However, the emergence of eSIMs takes convenience even further by enabling cellular plan activation directly from your phone without needing a physical card. eSIM profiles are stored digitally, allowing you to quickly switch between plans or manage multiple lines from one device. The eSIM approach simplifies the process for consumers.


Another plus for eSIMs is the ability to support multiple cellular plans simultaneously from different carriers. With a dual eSIM phone, you can have separate plans for work and personal lines in one device. You can’t do this with a single physical SIM card. The flexibility to activate plans over-the-air and manage multiple lines makes eSIMs the more agile, future-thinking option.


Both physical SIMs and eSIMs offer secure authentication and identification for network access. However, the risk of someone physically removing your SIM without your knowledge does not exist with eSIMs. Their embedded nature provides another layer of security from tampering. eSIMs win in this regard.


One clear advantage physical SIMs still have over eSIMs is universal compatibility. Almost all smartphones accept standard physical SIM sizes. eSIM adoption is still growing. You may find compatibility issues if your device or carrier doesn’t fully support eSIM technology yet.

Global Usability

For global travelers, eSIMs can be slightly less convenient than swappable physical SIMs. Remote activation of eSIMs while roaming depends on region and carrier availability. A physical SIM lets you simply use local SIMs as you travel. However, some eSIM providers like Uquid offer global compatibility so you can stay connected abroad.

A lot of users prefer a smartphone with both eSIM and a classic SIM card.

So which kind of SIM setup should you choose? While the transition is still ongoing, eSIM technology is likely the future thanks to its flexibility and digital focus. However, physical SIMs still work universally. Savvy users may want to enjoy the best of both worlds by having a smartphone with dual eSIM functionality alongside the classic SIM card slot. This allows you to reap the benefits of digital eSIM plans while retaining the global roaming accessibility of physical SIMs.
