PLDT lock/unlock NDD feature
This is an old feature of the PLDT phone system. To avoid bill shock from unwanted “long distance calls”, it may useful to use this feature.
I was curious if it is still working.
Instructions:
Your default PIN is “1234”
To change code: *85*Present Code*New Code# To lock: *54*Four digit code # To unlock: #54*Four digit code #
As of today, it still works.
