MMI codes, My Verizon app method, troubleshooting, and how to connect your Katch AI number in 60 seconds.
Quick Answer
Dial *71 followed by the 10-digit forwarding number and press call (busy forwarding). Or use My Verizon app → Account → Controls → Call Forwarding. To cancel: *73.
Sign up for Katch and get your forwarding number
Join the waitlist, download Katch, sign up with your Verizon number. You'll receive a unique Katch AI number to forward to.
Open your phone dialer
Dial the forwarding code and press call
Press the green call button. Wait for confirmation.
Test it
Have someone call your number while you're on another call. Katch should answer and send you a summary.
*71 not working on prepaid
Some Verizon prepaid plans restrict call forwarding via MMI codes. Use the My Verizon app or call 611 for activation.
Verizon Call Filter blocking Katch
Open Call Filter → Allow List → add your Katch number to prevent spam filters from intercepting forwarded calls.
Calls still ringing through
Verizon busy forwarding (*71) triggers only when you're on an active call. Set *72 (all calls) to test, then switch back to *71.
Cancel not working
Dial *73 and press call. Wait 5 seconds for the 'forwarding cancelled' tone.
Cancel all forwarding:
If you want a quick all-calls test, iPhone has a built-in path under Settings → Phone → Call Forwarding. Turn it on, enter your Katch number, then back out and give it a few seconds to save to Verizon. This route is useful when you want every incoming call to go to Katch right away, such as during a meeting, vacation day, or while checking that your Katch number is active. Keep in mind that the iPhone settings screen only handles unconditional forwarding. If you want calls to go to Katch only when you are busy or when you do not answer, use Verizon MMI codes from the dialer instead so you can keep normal ringing behavior.
Android steps vary a bit by phone maker, but Samsung and Pixel users usually open the Phone app, tap More, then go to Settings → Supplementary services → Call Forwarding. From there you may see separate entries for always forward, when busy, when unanswered, or when unreachable. If your menu is missing those items, do not assume the feature is unavailable. Many Verizon Android devices hide the menu and still accept MMI codes from the dialer. In practice, the dial-code route is often faster because it writes straight to the carrier setting and avoids menu differences between One UI, Pixel UI, and older Verizon firmware.
If the second phone goes to Verizon voicemail instead of Katch, forwarding did not save. Cancel with *73, wait a few seconds, and retry the setup.
Best practice for Katch on Verizon: set both busy and no-answer to the same Katch number so callers reach Katch whether you are tied up or simply miss the call.
*71 on Verizon covers busy and no-answer together
This catches people off guard if they have used AT&T before. Verizon often treats *71 as a combined busy and no-answer trigger, so one setup can cover both cases. That is why many Verizon users do not see separate short codes for each condition even though other carriers do.
Call Filter may flag your Katch number
If Verizon Call Filter labels the Katch forwarding number as unknown or risky, forwarded calls may not land where you expect. Open the Call Filter app, add the Katch number to your allow list or contacts, and run the second-phone test again after saving.
LTE can be easier than 5G Ultra Wideband for code registration
On some Verizon phones connected to 5G Ultra Wideband mmWave, MMI codes may fail to register on the first try. If that happens, switch to Settings → Network mode and force LTE, submit the code again, wait for the confirmation tone, then switch back to your usual network mode.
