In the landline world ‘star-codes’ like *67 are technically called VSC’s – Vertical Service Codes, or CLASS (Custom Local Area Signalling Services). Wikipedia.
I don’t know what they’re called for GSM service (GSM feature codes?), but GSMcodes will suffice for now.
http://geckobeach.com/cellular/secrets/gsmcodes.php has oodles more but most don’t work on Rogers.
Corrections & additions are most welcome.
If a code impacts “one outbound call” then the code should be entered right before the digits to dial, as a prefix to the actual phone number.
