How do I set up an eSIM after switching to a new phone carrier?

Answer

A new carrier eSIM usually cannot be installed until the carrier sends a QR code or pushes activation through its official app. Once that arrives, install the eSIM in the phone’s mobile/SIM settings, restart, and confirm the line shows active.

Before you start: stop right away if…

  • Deleting the only working SIM/eSIM before the new one is active can leave you without mobile service.

Follow these steps

  1. Confirm the carrier has issued the eSIM

    Sign in to the new carrier’s official app or account page and check whether an eSIM QR code, activation button, or “ready to install” status is available. If nothing is there yet, ask chat or support to send a fresh eSIM.

    You should see: You have a QR code or in-app install option for the new line.

  2. Install the eSIM on Wi-Fi

    Open the phone’s mobile/SIM settings, choose add cellular plan or eSIM, and scan the carrier QR code or continue in the carrier app. Keep the phone on Wi-Fi during install.

    You should see: The phone adds a new cellular plan and may ask to restart.

  3. Restart and select the new line

    Restart the phone, open SIM settings, and make sure the new carrier line is enabled for calls, texts, and mobile data.

    You should see: Signal bars return and a test call or data session works.

  4. Request a replacement eSIM if install fails

    If the phone still says no eSIM found after install, contact the carrier through the official app and ask them to cancel the failed profile and issue a new eSIM activation.

    You should see: A new QR or push install succeeds on a second attempt.

Extra tips

What to look for: Messages like no service, no eSIM found, or prompts to search for mobile plans after a same-day carrier switch.

Before you change anything: Stay on Wi-Fi so you can reach the carrier app or email. Have the account PIN or one-time code ready from the official carrier only. Do not delete the old eSIM until the new one is working unless the carrier says to. Never share account codes with unexpected callers.
