How do I set up an eSIM on a phone?
Answer
An eSIM has to be issued by the mobile carrier before the phone can activate it, so most setup problems come down to contacting the carrier for the activation, not a phone settings issue.
Follow these steps
Confirm eSIM support and carrier account status
Check that the phone model supports eSIM and that the mobile account with the carrier is active, either by signing in online or calling the carrier.
You should see: Both the phone and the account are confirmed ready for eSIM activation.
Request eSIM activation from the carrier
Sign in to the carrier's official account or call their support line and ask them to activate an eSIM for the specific phone model being used.
You should see: The carrier issues an activation code, QR code, or confirms the eSIM is ready to activate.
Connect to Wi-Fi before starting setup
Connect the phone to a Wi-Fi network, since eSIM activation usually needs an internet connection separate from cellular data.
You should see: The phone shows a stable Wi-Fi connection.
Activate the eSIM on the phone
In the phone's cellular or mobile network settings, choose to add an eSIM and follow the prompts, scanning a QR code or entering an activation code if provided by the carrier.
You should see: The phone confirms the eSIM is installed and active.
Confirm service is working
Check for a cellular signal indicator and try placing a call or sending a text to confirm the new eSIM line is working.
You should see: Calls, texts, or data work normally over the new eSIM.

Extra tips
What to look for: A message about an eSIM, activation code, or QR code during phone setup, or a failure message when scanning an activation code
Before you change anything: Confirm the exact phone model and whether it supports eSIM. Check whether the carrier account is active and in good standing. Confirm any QR code or activation link came directly from the carrier's official app, website, or store receipt. Never share account passwords or verification codes with anyone.
