E-sim Installation Guide
Huawei eSIM Installation Guide
1 Check if Your Device Supports eSIM
Go to Settings > About Phone > Show EID. If an EID number appears, your device supports eSIM (e.g., Huawei P40, P40 Pro, Mate 40 Pro). Also, ensure your device is network-unlocked.
2 Ensure Internet Connection
Make sure your device is connected to Wi-Fi or mobile data. A stable internet connection is required for eSIM activation.
3 Remove Conflicts with Other SIMs
Go to Settings > Mobile Network > SIM Management and disable or remove other eSIMs or physical SIMs. Huawei devices typically allow only one SIM for calls and data at a time.
4 Install Your eSIM
Using QR Code:
- Go to Settings > Mobile Network > SIM Management > Add eSIM
- Scan the QR code provided by Jett On
- Tap "Add eSIM" to confirm (Do not close the screen during installation)
Enter Details Manually:
- Go to Settings > Mobile Network > SIM Management > Add eSIM > Manual Entry
- Enter the SM-DP+ Address and Activation Code (Provided in your email or below your QR code)
- Tap "Add eSIM" and wait for the installation to complete (May take up to 10 minutes)
5 Set Jett On as Default Data Line
Go to Settings > Mobile Network > SIM Management, select the newly added eSIM, rename it to "Jett On", and set it as the default data line.
Disable the physical SIM to prevent it from consuming data.
6 Enable Data Roaming
Go to Settings > Mobile Network > SIM Management > Jett On and enable "Data Roaming". This is required for the eSIM to work.
7 Refresh Network Connection
Turn on Airplane Mode for 10 seconds, then turn it off. This refreshes the network signal.
8 Test Your Internet
Open Chrome or another browser to check your connection. If the page loads, your eSIM is working!
