An eSIM (embedded SIM) is a digital version of the traditional SIM card — it's built directly into your device, allowing you to activate a mobile plan without inserting any physical card.

With AetopOne, you can install and activate your eSIM in just a few minutes, giving you instant data access across 190+ countries. Whether you're preparing for an international trip, switching devices, or simply want to stay connected seamlessly, this guide explains everything you need to know.

1. Before You Start

Before installing your eSIM, make sure:

Your device supports eSIM functionality.
You are connected to a stable Wi-Fi or mobile data network.
You have purchased your eSIM plan from AetopOne.com and received your QR code or activation details via email or in the app.

Check compatibility:

2. Installing Your eSIM on iPhone

Open Settings → Cellular (or Mobile Data)
Tap Add eSIM or Add Cellular Plan
Select Use QR Code
Scan the QR code provided by AetopOne
Label your new plan (for example, "AetopOne Travel")
Set Data Roaming to ON and select AetopOne as your Primary Data Line

Your eSIM will activate automatically. You can continue using your regular SIM for calls while AetopOne handles your data connection.

3. Installing Your eSIM on Android

For Samsung Devices

Open Settings → Connections → SIM Manager
Tap Add eSIM
Choose Scan QR Code
Scan your AetopOne QR code
Confirm installation and enable Mobile Data

For Google Pixel Devices

Open Settings → Network & Internet → SIMs
Tap + Add SIM → Download a SIM instead
Scan your AetopOne QR code
Confirm and activate

Once complete, your phone will automatically connect to the best available local network.

4. Manual Installation (Without QR Code)

If you prefer to install manually or if your device cannot scan QR codes, use the SM-DP+ Address and Activation Code included in your AetopOne confirmation email or app.

Steps:

Go to Settings → Cellular/Mobile Data → Add eSIM → Enter Details Manually
Enter the SM-DP+ Address and Activation Code
Tap Next and follow on-screen instructions until activation is complete

5. Managing Your eSIM

Once installed, you can easily manage your eSIM from your device settings:

Switch between eSIMs: Toggle between your local and travel plans.
Rename your plan: Give your AetopOne eSIM a custom name.
Disable or delete: Remove the plan when your trip ends.
Add new eSIMs: Download additional AetopOne plans for future destinations.

All management options are located in your device's Cellular / SIM Manager section.
