Symptoms
- Calls don't forward to the intended number
- Forwarding turns off unexpectedly
- Setup code doesn't seem to take effect
- Forwarding works for some calls but not others (like when busy or unanswered)
Likely causes
- CommonForwarding not activated with the correct carrier code or app settingCall forwarding often needs a specific dial code or a toggle in a carrier app, not just phone settings.
- CommonWrong number entered for forwardingA typo in the forwarding number will silently fail or forward to the wrong place.
- PossibleDifferent forwarding types (all calls vs. busy vs. unanswered) not configured correctlyThese are often separate settings that need to be set individually.
- Less commonCarrier account restriction on the featureSome plans require the feature to be added or enabled on the account.
What to do
- Confirm which type of forwarding you want (always, when busy, when unanswered) and set each one specifically if needed.
- Double-check the destination number for typos, including the area code.
- Use your carrier's official app or dial code for call forwarding rather than relying solely on phone software settings.
- Test by calling your own number from another phone to confirm forwarding works as expected.
- Turn forwarding off completely and set it up again from scratch if it seems to be in a broken state.
- Contact your carrier to confirm the feature is enabled on your plan.
When to call a pro
If forwarding still fails after correct setup and a test call, contact your carrier's support, since this feature is often controlled server-side.
