An eSIM is a digital cellular plan, so setup depends partly on your carrier. Supported carriers can use automatic activation, Quick Transfer from another iPhone, a QR code, a carrier app, or another activation method.
Quick steps
- Connect the iPhone to Wi-Fi.
- Open Settings and tap Cellular.
- Tap Add eSIM or Set Up Cellular.
- Choose the transfer, QR-code, carrier, or other option offered for your plan.
- Follow the carrier prompts until activation completes.
- Test a call, text message, and cellular data.
Quick Transfer can avoid a carrier call
With participating carriers, eSIM Quick Transfer can move a phone number from an old iPhone to a new one without contacting the carrier. Both devices need to meet Apple’s software and account requirements, and carrier support still determines whether the option appears.
QR codes and carrier apps
If Quick Transfer is unavailable, the carrier may provide a QR code, activation link, or app. Use activation information from the carrier rather than a QR code from an unknown source, because the eSIM controls access to your cellular line.
Dual SIM and multiple numbers
iPhone can support more than one stored eSIM, and current software can transfer multiple numbers in supported situations. Labeling lines as Personal, Business, or another useful name makes it easier to choose the correct line for calls and cellular data.
Do not delete an eSIM as routine troubleshooting
Removing a working eSIM can create more work because the carrier may have to activate it again. Try airplane mode, a restart, carrier settings, and normal network troubleshooting first unless the carrier specifically tells you to delete the plan.
One more detail worth knowing
Setting up an eSIM on your iPhone 14 is a straightforward process that allows you to activate a cellular plan without needing a physical SIM card. Essentially, you’ll be downloading a digital version of your SIM card directly onto your phone. By following a few simple steps, you can activate an eSIM and enjoy seamless connectivity.
How to confirm the change
After you finish add/activate esim, repeat the action that originally brought you to this guide. Check the visible setting or real-world result rather than assuming the change took effect. If the result differs from the steps above, return to the relevant menu and look for a carrier, account, device, or app-specific control before changing unrelated iPhone settings.
Set up an eSIM from the carrier or transfer flow
Open Settings > Cellular or Mobile Service and choose Add eSIM or Set Up Cellular. Depending on the carrier and devices involved, the iPhone can offer transfer from another phone, carrier activation, a QR code, or manual details.
Do not delete the old line too early
Keep the previous SIM or eSIM active until the new iPhone can make calls, receive texts, and use cellular data. If activation fails, the carrier may need the new iPhone’s identifying information or may need to issue a new eSIM profile.
