Call forwarding, relevant commands edition

This is widely documented around the internet, but everything has a lot of details irrelevant to my case of two phones and it’s always effort to cherry-pick the relevant parts. This file may be unintentionally Finland specific.

1. Open dialer
2. Enter command. +358 is Finnish international format, remove leading 0 from phone number’s local format. (040… → +3584…)
3. Call there

Commands

• ##002# - Remove all call forwards
• **61*+358…**30# - forward if call is not answered in 30 seconds
  • 30 may be replaced with multiples of 5 between 5 and 30.
• **62*+358…# - forward if phone is not connected to network.
• **67*+358…# - forward if phone is on another call.

Copy-paste template for text editor:

**61*+358…**30#
**62*+358…#
**67*+358…#

Status check

• *#002# - Supposedly status for all forwards. Will respond with everything has failed.
• *#61# - Status for forward while not answered. Doesn’t show the amount of seconds as that would likely make life too easy?
• *#62# - Status for forward when not connected to network.
• *#67# - Status for when being in other calls.

GUI

• Apple: has no proper GUI for the cases above, only on/off toggle on forwarding every call. https://support.apple.com/guide/iphone/iphe9bdd027a/ios
• Android: likely OEM-dependent and I don’t have an Android with a SIM.
• SailfishOS: Settings → Applications → Phone → Call forwarding. Case forward when not answered in X time has no option how long to wait and I am not going to try whether it forwards in 5 or 30 seconds.
