Does the Galaxy S25 Ultra Support eSIM? 3 Easy Activation Steps

Staying connected has become the priority of smartphone users. This need has paved the way for a form of wireless connectivity called eSIM. This is wireless connectivity without the hassle of physical SIM cards. Many tech giants like Samsung, Apple, and OnePlus incorporate eSIM into their smartphones. In this guide, we'll confirm if Samsung will retain this feature for its new release: the Samsung Galaxy S25 Ultra.

If you plan to buy the Samsung Galaxy S25 Ultra, we’re excited to tell you more about its eSIM functionality. We will start by defining eSIM, and later on, we’ll answer the question: Does the Samsung Galaxy S25 Ultra support eSIM?

eSIM, short for embedded SIM, is a form of advanced tech that eliminates the need for a physical SIM card. Unlike traditional SIMs that need to be inserted and swapped manually, an eSIM is built directly into your phone’s hardware and activated remotely.

For Samsung Galaxy phones, eSIM allows users to connect to a mobile network, make calls, send texts, and use data like a regular SIM card. The convenient part is that cellular plan activation can be done without a physical card.

An eSIM works by embedding a programmable SIM chip directly into your S25. This lets you connect to a mobile network without inserting a physical SIM card. Unlike traditional SIM cards that store network credentials on a removable chip, an eSIM holds this information digitally. It can also be updated or changed remotely, removing the hassle of manually swapping physical cards whenever you swap carriers.

When you activate an eSIM, your carrier sends the necessary network settings over the air, which are then securely stored on your device. You can add, remove, or switch mobile plans simply through your phone’s settings without needing a new SIM card. It’s a pretty neat and secure piece of tech, and the question falls on whether the Samsung Galaxy S25 Ultra will support it. Let’s find out.

Yes, the Samsung Galaxy S25 Ultra is expected to support eSIM. The Galaxy S25 series is also expected to support dual-SIM.

Reports suggest an anticipated transition of Samsung’s Galaxy S25 series to eSIM-only configurations in certain markets, notably the United States. This strategic move mirrors Apple’s earlier adoption of eSIM technology with the iPhone 14.

eSIM technology introduces a completely digital setup. Users can purchase, install, and connect to a carrier remotely through their settings. In-store visits are no longer necessary, as switching providers or adding a new plan is handled digitally.

One of the standout features of eSIM is its ability to store multiple profiles. Swapping SIM cards is no longer necessary since users can now toggle between carriers directly from their phone’s settings.

Beyond functionality, removing the traditional SIM tray means better water and dust resistance, as there are fewer openings where moisture or particles can enter. The extra internal space from the SIM tray can be used for other components, such as larger batteries, for improved performance and battery life.

Finally, if the Samsung S25 goes eSIM-only, the need for plastic SIM cards and their packaging will help cut waste and lower the carbon footprint associated with SIM card production and distribution. With millions of SIM cards being manufactured and discarded yearly, transitioning to eSIMs is a step toward a more sustainable environment.

Activating an eSIM is quick and hassle-free. eSIM technology makes managing your plan directly from your phone easy. In this guide, we’ll walk you through three simple methods to activate your eSIM so you can start enjoying seamless connectivity in no time. Ready to activate? Let’s start.
