How can I disable the FPLMN function?
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.
