The most radical way is to take the card out of the slot, but there are a few pitfalls in Xiaomi devices:

  1. On most models (Redmi Note 12, Xiaomi 12T) the slot is hybrid: either two nano-SIMs, or one SIM + microSD. If you take out the second card, the memory slot will remain free.
  2. On flagships (Xiaomi 13 Ultra, MIX Fold 3) can be a separate slot for the second eSIM – it is turned off software.
  3. On some devices (e.g., the POCO X5 Pro), after the SIM is removed, the system continues to show it in the settings as "Unidentified." To remove the ghost card, you will need to reset the network.

  • πŸ› οΈ Hardware malfunction: If the slot is damaged (for example, after a phone drop), the contacts can close, and the system "sees" the card even without it.
  • πŸ€– Conflict with Dual Apps: If you cloned messengers (WhatsApp, Telegram) for the second SIM through settings β†’ Annexes β†’ Dual Apps, the system can automatically activate the line.
