Secret iPhone codes

*#21# and tap Call. Setting interrogation for call forwards.

Discover the settings for your call forwarding. You'll see whether you have voice, data, fax, sms, sync, async, packet access, and pad access call forwarding enabled or disabled.

*#30# and tap Call. Calling line presentation check.

This displays whether you have enabled or disabled the presentation of the calling line, presumably the number of the party placing the call.

*#76# and tap Call. Check whether the connected line presentation is enabled or not.

State whether the connected line presentation is enabled or disabled. Presumably similar to the calling line presentation.

Displays call waiting status for voice, data, fax, sms, sync data, async data, packet access and pad access. Each item is either enabled or disabled.

*#61# and tap Call. Check the number for unanswered calls.

Show the number for voice call forwarding when a call is unanswered. Also show the options for data, fax, sms, sync, async, packet access and pad access.

*#62# and tap Call. Check the number for call forwarding if no service is available.

Just like the previous, except for no-service rather than no-answer situations.

*#67# and tap Call. Check the number for call forwarding when the iPhone is busy.

And again, but for when the iPhone is busy.

*#33# and tap Call. Check for call control bars.
