How to Check if Your Phone Supports eSIM and Request a Refund

Device compatibility requirements

For a virtual SIM profile to function properly, your device must meet the following criteria:

• Hardware eSIM module: The device must have a built-in eSIM chip with a unique EID identifier.

• No regional hardware restrictions: Certain models manufactured for mainland China, Hong Kong, and Macao feature two physical SIM slots and lack an embedded eSIM chip.

• Carrier unlocked (No SIM-lock): The device must not be locked to a specific telecom network under a carrier contract.

Method 1. Universal check via USSD code (iOS and Android)

1. Open the Phone app (dial keypad).

2. Dial: *#06#.

3. Review the device identification screen and look for the EID field (a 32-digit number accompanied by a barcode):

   • EID is displayed: Your device has built-in hardware support for eSIM technology.

   • Only IMEI 1, IMEI 2, MEID, or Serial Number (SN) are shown without an EID: The device only supports physical plastic SIM cards.

Method 2. Checking through device settings

• On iOS (iPhone / iPad):

  • Go to Settings > Cellular (or Mobile Data). The presence of an Add eSIM (or “Add Cellular Plan” / “Set Up Cellular”) option confirms eSIM capability.

  • Carrier lock verification: Go to Settings > General > About > Carrier Lock. It must state "No SIM restrictions". If a specific carrier is listed, third-party eSIMs cannot be activated.

• On Android (Samsung, Xiaomi, Google Pixel, etc.):

  • Go to Settings > Connections (or Network & internet / SIM cards & mobile networks) > SIM manager (or Manage eSIM).

  • The presence of the Add eSIM (Add mobile plan) option confirms hardware compatibility.

Alternative: Physical eSIM Adapter

If your phone does not have an integrated eSIM module, you can use a dedicated physical eSIM adapter from Unilink, which fits into a standard plastic SIM tray. Contact our support agent in the chat to check availability and order details.
