A device incorporates an eSIM (embedded SIM), a sort of programmable SIM card. In place of an integrated circuit that is stored on a detachable universal integrated circuit card (UICC), which is often made of PVC, an eSIM consists of software put onto an eUICC chip that is permanently attached to a device.
When an eUICC is configured with an eSIM carrier profile, it performs just like a physical SIM, complete with a unique ICCID and network authentication key generated by the carrier.
The eSIM standard has begun to replace physical SIM in a number of industries, including cellular telephony since it was first introduced in 2016.
You can activate a cellular plan with your carrier using an eSIM, an industry-standard digital SIM, without using a physical SIM. On an iPhone, eight or more eSIMs can be installed, and two phone numbers can be used simultaneously.
How do I activate eSIM on my iPhone 14?
Turning on your new iPhone and following the onscreen prompts typically suffices to configure your eSIM.
If your carrier enables eSIM Carrier Activation or eSIM Quick Transfer, you can activate your eSIM at the same time as configuring your iPhone. When you buy an iPhone, your carrier gives it an eSIM through eSIM Carrier Activation.
Without contacting your carrier, you can transfer the SIM from your old iPhone to your new iPhone using eSIM Quick Transfer. Using either technique, turn on your iPhone and follow the on-screen instructions to activate your eSIM during setup.
Later on, you can add or move an eSIM using these options as well. In the absence of these choices, speak with your carrier to activate your eSIM with a QR code
If your carrier activated an eSIM after you requested one and after configuring your iPhone, you should take the following actions:
Touch the area where it reads “Carrier Cellular Plan Ready to Be Installed.”
From the Settings app, choose Carrier Cellular Plan Ready to Be Installed
