What is an eSIM, how does it work, and why should you use it?
La eSIM (Embedded Subscriber Identity Module) is a chip integrated into the hardware of your device, which completely replaces to the traditional physical SIM. Unlike the plastic SIM, the eSIM cannot be removed; it comes pre-installed in your Android phone, tablet, smartwatch, or even your Chromebook. When you install an eSIM, your carrier profile (number, network settings, data, etc.) is digitally downloaded and securely stored.
This innovation brings great advantages at the user level:
- You don't need physical cards: Change carriers or add a new number without opening your phone.
- Multi-profile: Manage multiple lines at once (personal, work, travel) and switch between them easily.
- Ideal for travelers: Install and activate international eSIMs instantly in over 170 countries without relying on traditional roaming.
- Greater security: If your phone is lost or stolen, the eSIM cannot be removed or reused by others without your permission.
- Retrench of space: Without a physical SIM tray, manufacturers dedicate that space to improving battery life, audio, or water resistance.
- More stable connection: Avoid physical reading problems or deterioration of the traditional SIM.
Due to its versatility, the eSIM is present in mid- and high-end Android phones from brands such as Samsung, Google Pixel, Xiaomi, OPPO, Sony, Honor, Nokia, among others, and each year more models are added to the list of compatible devices.
Is my Android phone compatible with eSIM? Universal methods to check
Before any purchase or installation, verify that your device supports eSIM. You have several effective and complementary methods:
- Check the manufacturer's official website: Find your model on the website and check the “Connectivity” or “SIM Card” section.
- EID code: Brand * # # 06 in the phone app. If an EID (Embedded Identification Document) code appears, your Android supports eSIM.
- System settings: Go to Settings > Network & Internet (or Connections) > SIM or SIM Manager. If you see options like “Add eSIM” or “Manage eSIM,” you have support.
- Lists of operators and eSIM providers: Many carriers and eSIM specialists (Holafly, Airalo, Roamless, etc.) maintain up-to-date lists of compatible phones.
- In your carrier's app: Some national operators include a compatibility check in their own official app.
Some models offer the option to add an eSIM directly in the SIM card menu. If your phone displays the "EID" field next to the IMEI, compatibility is confirmed.
Essential preparations before installing your eSIM on Android
To avoid mistakes and ensure a quick and safe installation, keep these key points in mind:
- Android device compatible with eSIM and without carrier lock
- Stable WiFi connection or mobile data with good coverage (better WiFi if you are abroad)
- Email or PDF from your carrier or global eSIM provider with the QR code, SM-DP+ address and activation code.
- Read the instructions carefully: Some international carriers activate the eSIM only upon arrival in the destination country. Read whether the validity period begins after installation, activation, or scanning.
- Prepare a physical or digital copy of the QR/codesIf you're traveling, keep them saved on your secondary phone, tablet, or on paper in case you need to reinstall them.
Remember: An eSIM can only be activated once per QR code/SM-DP+ code. If you remove your eSIM, you'll usually need to request a new profile from your carrier or provider.
