How to make an anonymous call from your iPhone
If you want to make a call but don’t want to let the giant marketing company/slightly weird stranger you are about to talk to learn your number, you can very easily make your call anonymous.
Just tap #31#
Apple’s iPhone has a smart way to protect your number – and while many iPhone users (including myself) think twice when we receive a call we cannot identify that fails to share its number using Caller ID, it may be worth using when you want to remain a little anonymous.
To use this feature, just dial #31# before you dial the number.
You can even add #31# to the front of a person’s number in your Contacts book, if you want to automate anonymity with that contact. Finally, if you dial #31# without a subsequent number you will turn off Caller ID for all future calls on that iPhone (just dial the same code again to switch it on again).
Two more tips
- You can find your iPhones IMEI number (useful when changing networks) by typing this code: *#06#
- Kick out interruptions, just dial *#21# to push all incoming calls to voice mail, dial it again to take calls again.
