Can I install the same eSIM on multiple devices simultaneously?

The introduction of eSIMs in smartphones has made switching carriers, managing mobile plans, and staying connected while overseas easier than ever. However, many users are curious about whether they can install an eSIM on multiple devices simultaneously. In this article, we’ll explore how eSIMs work, the limits of their use, and how to effectively manage them across multiple devices.

What is an eSIM?

An eSIM, short for embedded SIM, is a digital SIM card embedded within your device, eliminating the need for a physical SIM card. It allows you to activate a mobile plan directly on your eSIM-compatible device without the hassle of swapping physical SIM cards.

Instead of inserting a physical SIM card in your phone, eSIMs work through the installation of an eSIM profile. The eSIM profile is somewhat like a piece of software, which consists of the necessary information required for a network to authenticate and authorise the connection.

Can You Use the Same eSIM on Multiple Devices?

Since an eSIM is digital, some might be wondering if you can use the same eSIM - or install the same eSIM profile - on multiple devices simultaneously.

The short answer is no—an eSIM cannot be installed on multiple devices simultaneously. Here’s why:

1. Unique Activation Profiles

Each eSIM comes with a unique activation profile tied to a specific device. Once the eSIM profile is downloaded onto a device, it cannot be reused on another device unless it is transferred or reissued by your carrier.

2. Carrier Restrictions

Mobile carriers often lock eSIM profiles to a single device for security and billing purposes. Attempting to use the same eSIM on multiple devices could violate your carrier’s terms of service.

What if I need to stay connected on multiple devices?

If you need to stay connected on multiple devices, there are a few options.

You could consider buying multiple eSIMs, one for each device that you need — assuming all of them are eSIM-compatible. While eSIMs can only be installed on a single device, depending on your provider, you need not necessarily install the eSIM on the device that you used for your eSIM purchase.

If you purchase a Nomad travel eSIM for your trip, you will receive an email with a QR code. You can simply scan that QR code using the device that you want your eSIM to be installed on. But remember, eSIMs can only be installed once so if you have already installed your eSIM on one device, you wouldn’t be able to install it on another.

Alternatively, you can consider getting a plan that allows you to hotspot or tether data. This way, you can turn your primary device that has the eSIM installed into a hotspot for your other devices to connect to the internet.

Stay connected when you travel with a Nomad eSIM

While you can’t install a single eSIM on multiple devices simultaneously, the flexibility of eSIM technology makes it easy for you to purchase multiple eSIMs and have them installed on your various devices.

If you will be traveling internationally, travel eSIMs are a convenient and affordable solution to helping you stay connected.

There are many providers of travel eSIMs, and one of the best options is to get a Nomad eSIM. Nomad offers connectivity in over 190+ destinations worldwide, including popular travel destinations like the United States, United Kingdom, and Japan. If you will be traveling to multiple countries, Nomad also offers regional plans, offering seamless internet connectivity as you travel across the various countries.
