Most people know you can dial *118# or something similar to check how much data you have left. However I recently learned that other country phone company got a lot more feature. Example:

Feature Activate Deactivate
Call Forwarding *72 *73
Call Waiting Switchhook/Flash
Cancel Call Waiting *70
Three-Way Calling Switchhook/Flash
Speed Dialing See instructions
Automatic Recall *69
Anonymous Call Rejection *77 *87
Caller ID Suppression *65
Caller Name Blocking *63
Caller Number Blocking *67 *82
Selective Call Acceptance *64 *84
Selective Call Forwarding *62 *83
Selective Call Rejection *60 *80
Distinctive Ring *51
Call Trace *57
Call Forward Busy Call Socket
Call Forward No Answer Call Socket
Outbound Call Blocking Call Socket

I wonder if local telco got these kind of feature or not? And if got how come there is no documentation? Or they figured that average Malaysian will never use these things, and never bothered hosting them?

Some of these are documented here:

Problem is call forward will deduct the call credit or not?

if the forwarded call connects, yes it will be charged (or deducted from plan minutes)

some prepaid, example hotlink, don't allow call forwarding/divert
