Phone & call answers
41guides covering the dial codes, carrier paths, and device settings you need to forward calls, set up voicemail, block spam, or troubleshoot your business line — without sifting through your carrier's support pages.
Star codes & USSD
7 guides
Reference for the dial codes that control call forwarding, last-call return, and other carrier features.
*72 call forwarding — what it does and how to use it
The classic North-American forward-every-call star code. Works on Verizon, Bell, Telus, Spectrum, and most landline + cable VoIP carriers.
*71 call forwarding — what it does and how to use it
The classic conditional-forward star code. Routes only the calls you'd otherwise miss — keep answering the rest yourself.
*73 — how to cancel call forwarding
One short code clears both *72 (forward every call) and *71 (forward on busy / no answer). Works on Verizon, Spectrum, Bell, Telus, and most landline + cable VoIP carriers.
What does **21* and ##21# mean?
**21* sets unconditional call forwarding. ##21# cancels it. Two codes, one feature, every GSM carrier.
What does *69 mean?
Dial *69 and your phone calls back the last number that called you — useful for the missed call you couldn't catch in time.
USSD codes — what they are and how to use them
Short dial strings that talk straight to your carrier's network. Used for call forwarding, balance checks, IMEI lookup, and more — work on every GSM phone.
Call diversion codes — full reference by carrier
"Call diversion" and "call forwarding" are the same feature with two names. Same GSM USSD codes apply across the US, UK, and most international networks.
