What are eSIMs?
Definition and basic concept
An eSIM, or embedded subscriber identity module, is a small chip built into your phone, tablet, or smartwatch. Think of it as a digital version of the physical SIM card you’re probably used to. Instead of needing to physically swap out SIM cards, an eSIM lets you activate a cellular plan directly from your device’s settings. This means you can switch carriers or have multiple phone numbers on a single device with ease. You can even have multiple eSIMs on one device—eight or more on some iPhones, for example—and use two numbers simultaneously. This is particularly handy for people who want to keep their personal and business lines separate or for frequent travelers needing local numbers in different countries.
eSIMs vs. traditional SIM cards
The main difference between an eSIM and a traditional SIM card boils down to convenience and flexibility. With a traditional SIM, you need a physical card for each carrier or plan. Switching carriers means physically swapping out the SIM card in your phone. An eSIM eliminates this, letting you switch carriers or add a new line with a few taps on your screen. This digital format also means no more fumbling with tiny SIM cards or worrying about losing them. While eSIM technology is becoming increasingly common, not all carriers and devices support it yet. However, as more devices and carriers adopt eSIM technology, its benefits are becoming more accessible.

Setting up your eSIM
Step-by-step guide
Setting up an eSIM is generally straightforward. For a new iPhone, simply follow the on-screen prompts. Your carrier might use “eSIM Carrier Activation,” where they assign the eSIM, or “eSIM Quick Transfer” to move it from your old iPhone. If your previous iPhone is nearby, unlocked, has Bluetooth enabled, and runs iOS 16 or later, the transfer is even simpler.
Often, you’ll receive a QR code from your carrier. Just scan this code with your iPhone’s camera app. Alternatively, some carriers might send a link. If neither a QR code nor a link is provided, you can manually enter the eSIM details in your iPhone’s settings after contacting your carrier for the necessary information. In some cases, you can even convert an existing physical SIM to an eSIM, or transfer a SIM from an old iPhone to a new one, directly through your phone’s cellular settings.
Troubleshooting common issues
While eSIM setup is usually easy, you might occasionally hit a snag. If you’re setting up an eSIM after the initial iPhone setup, check with your carrier for specific instructions. After activating an eSIM that replaces a physical SIM, remove the physical SIM and restart your iPhone. This simple step often resolves minor issues.
If you continue to experience problems, ensure your device is compatible with eSIM technology and that you have a stable internet connection during setup. Confirm with your carrier that the eSIM is activated and that there are no service outages affecting your area. Some carriers also offer dedicated apps that can assist with eSIM activation and management.
