Apple iPhone – Adding Extensions to Phone Numbers

Here’s how to add extensions to Phone Numbers on an Apple iPhone:

1. On the iPhone, launch Contacts app (note: the Phone app will also work).
2. Tap the “+” (top-right) to add a new contact. If you’re editing an existing contact, just tap the contact and then tap on Edit.
   
3. In the phone number field, you type the number and then tap on the “+*#” button to bring up more options.
   
4. For an extension number that you type immediately after dialing the number, use Pause. This adds a “,” to the phone number.
   
5. For a prolonged pause, use Wait and then key in the number. This adds a “;” to the phone number.
6. Tap Done to save the changes.
7. Make sure you test it out after saving the contact number.
