Service code 35 is BAIC, Barring of All Incoming Calls. Callers are rejected at the switch before your iPhone is ever paged, so the phone stays silent and never shows a missed call. Where voicemail is configured to catch unreachable calls, callers may land there instead. This is not Do Not Disturb and not a Focus mode. Both of those are iPhone features that still let the call reach the device. Barring happens in the carrier network and follows your number into any handset. Replace 0000 with your call barring password. **Important:** If this succeeds you will stop receiving calls entirely, including from your carrier and from two factor voice callbacks, and the only way back is #35*password# or a call to support. Nothing on the iPhone will indicate why calls have stopped. ## How do I use *35*0000#? - Open the Phone app and tap Keypad. - Type *35*0000# exactly as written. - Press the green Call button and wait for the result. ## Which carriers does this apply to? | Published for | AT&T and T-Mobile | | Type | Support varies | | Good to know | Very rarely provisioned in the US.
