How to Fix Galaxy S26 eSIM Not Activating After Update

A Galaxy S26 can fail to activate eSIM after an update if the carrier profile did not re-register correctly, the modem did not finish initializing after reboot, or the eSIM line was left in a pending state during the update process.

If you want broader help for this device family, visit the Galaxy S26 support hub. You may also need one of the closely related fixes below if the problem started after the same update.

Related fixes worth checking

Fix #1: Force restart the phone

Hold the Side button and Volume down until the device restarts. This often clears a temporary eSIM registration freeze.

Fix #2: Check SIM manager and line status

Go to Settings > Connections > SIM manager and make sure the eSIM line is enabled. If the line is disabled or missing, toggle it off and on if available.

Fix #3: Reconnect to Wi-Fi and retry activation

eSIM activation usually needs a stable internet connection. Connect to a reliable Wi-Fi network and try finishing the activation again.

Fix #4: Delete and re-add the carrier plan if the carrier approves it

If the activation remains stuck, ask the carrier whether you should remove the broken profile and scan a new QR code. Do not delete the plan first unless the carrier confirms a replacement is ready.

Fix #5: Reset network settings

A network reset can clear damaged registration data that blocks eSIM activation after an update.

Fix #6: Contact the carrier for reprovisioning

If the IMEI/EID pairing did not update correctly on the carrier side, only the carrier can finish activation by refreshing the eSIM profile.

When to contact support

If none of the steps above fix Galaxy S26 eSIM not activating after update, the issue may involve a carrier-side provisioning fault, a hardware failure, or a software bug that needs a follow-up patch. Back up your data and contact the carrier, Apple, or Samsung support if the problem continues.
