Set up eSIM on Galaxy S25

Setting up eSIM on a Galaxy S25 is quick once you have the right carrier details ready. This guide covers all common activation paths: QR code, automatic carrier download, and manual activation code entry.

Before you begin eSIM setup

• Make sure your carrier supports eSIM on Galaxy S25.
• Connect the phone to Wi-Fi (recommended during activation).
• Prepare one of these from your carrier: QR code, pre-assigned plan, or activation code.
• If your carrier asks for EID, find it in Settings > About phone > Status.

2. Tap Connections.
3. Tap SIM manager.

Option 1: Set up eSIM by scanning a QR code (most common)

1. In Add mobile plan, choose Add using QR code (wording can vary by carrier/region).
2. Point camera at the carrier QR code.
3. When plan details appear, tap Add or Confirm.
4. Wait for download and activation to finish.
5. If prompted, restart the phone.

Option 2: Set up eSIM with pre-assigned carrier plan

1. Tap Add mobile plan.
2. If your carrier supports auto-discovery, the plan appears automatically.
3. Select the detected plan and continue activation.
4. Finish on-screen prompts and wait for network registration.

Set preferred SIM for calls, texts, and data

How to remove an eSIM later

1. Go to Settings > Connections > SIM manager.
2. Select the eSIM plan you want to remove.

Removing an eSIM from the phone does not always cancel your carrier plan. Contact carrier if you also want service cancellation.

If eSIM activation fails

• Check Wi-Fi and retry activation.

• Ensure device is carrier-unlocked if required.
• Update Galaxy S25 software, then try again.
• Call carrier support and provide EID for manual provisioning help.

Once activated, your Galaxy S25 should show signal bars for the eSIM line and appear as active in SIM manager.
