How do I forward only the calls I don’t answer?
Use your carrier’s "no answer" (conditional) forwarding, not the phone’s plain Call Forwarding switch. On Verizon and Xfinity Mobile you dial *71 followed by the 10-digit number. On T-Mobile, whose short-codes page lists it, and on AT&T and most prepaid brands, the standard GSM code is **61* followed by 1, the 10-digit number and #, or you can set "When unanswered" in Android’s call settings. Then test it by calling yourself from another phone and letting it ring.
Why does iPhone call forwarding send every call away?
Because that is what it does. Apple’s Settings › Apps › Phone › Call Forwarding forwards every call to one number, so your phone stops ringing. Apple says that for forwarding only when busy or unanswered you should get the setup from your carrier. Use the carrier code instead and leave that switch off.
What is the Verizon code for no-answer forwarding?
Dial *71 followed by the 10-digit number you want unanswered calls to go to. Verizon describes it as forwarding only the calls you don’t answer. *72 forwards every call, and *73 turns forwarding off.
How long does my phone ring before an unanswered call forwards?
It depends on the carrier. On GSM networks such as T-Mobile and AT&T you can usually set it in the code itself by adding the seconds before the final #, for example **61*1 + number + **20#, with values from 5 to 30 seconds. Verizon does not publish a setting for it.
Will forwarding unanswered calls break my voicemail?
Yes, while it is on. The calls you don’t answer go to the forwarding number instead of your voicemail. Xfinity says this outright. If the number you forward to has its own voicemail, callers can still leave a message there.
Does call forwarding cost extra?
Usually not on current plans, but check. Verizon says there is no monthly fee on most plans, that a fee may apply on some older plans, and that per-minute charges may apply to forwarded calls.
How do I turn it off?
On Verizon, Xfinity Mobile and Visible dial *73. With the GSM codes, ##61# turns off no-answer forwarding and ##004# clears every conditional forward at once.
