Likely causes
- CommonWeak or interrupted Wi-Fi connection during transfereSIM activation typically needs a stable internet connection to complete the carrier handshake.
- CommonCarrier-side activation delaySome carriers take a few minutes to hours to fully process an eSIM transfer or activation.
- PossibleQR code already used or expiredMost eSIM QR codes are single-use and expire after a set time.
- PossiblePhone not compatible with eSIM or carrier-lockedSome phones, especially those bought used or through certain carriers, may have eSIM restrictions.
- Less commonCarrier account issue blocking the transferBilling or account status problems can prevent an eSIM from activating.
What to do
- Make sure the new phone has a strong, stable Wi-Fi connection before starting the transfer.
- If using a QR code, confirm it hasn't already been used or expired, and request a new one from your carrier if needed.
- Wait 10–15 minutes after the transfer process completes, since activation can take time on the carrier's end.
- Restart both phones after attempting the transfer.
- Check your carrier's app or website for eSIM transfer status or errors.
- If using the direct transfer feature between two phones, ensure both are updated to the latest software.
- Confirm the new phone isn't carrier-locked if it came from a different provider or was bought used.
- If the eSIM still won't activate after 30–60 minutes, contact your carrier directly for manual activation.
When to call a pro
If the eSIM won't activate after 30–60 minutes and multiple attempts, contact your carrier for manual activation support.
