  • SIM type: applicable to all

Question

  • How can I disable the FPLMN function?

  • Why is my SIM on the FPLMN list?

Answer

  • You cannot disable FPLMN.

  • Instead, consider implementing firmware logic for automatic FPLMN clearing.

  • Contact your modem / module manufacturer for assistance.

Cause

The FPLMN is a part of global telecommunication standards and cannot be disabled, neither on the SIM level nor the device level.

If your modem has written local networks onto the FPLMN list on the SIM - it won't connect with them until you clear the list.
