Dialing a phone number extension on your iPhoneand Androidis very easy. However, dialing on Android has two different methods. In this walkthrough, we will be talking about how to dial a phone number extensionon your mobile device.
For iPhones, enter the main number or building number, press and hold the ***** key until a comma appears in the number, enter the extension, and send the call as usual.
Now, locate the contact whose extension you’d like to add by opening your contact list.
Click the person’s name. On the Phone app, the contact information slides into view. On the Contacts app, the contact information page displays.
Choose the Pencil icon.
Tap the phone number field and place the cursor at the end of the phone number. The on-screen keyboard appears.
Insert a single comma to the right of the phone number.
Edit button and comma placed in the phone number on Android
Note: The comma may be replaced by a Pause button on some devices, or your device may also include both.
Then you type the extension number for the contact after the comma or pause. For example, if the number is 01234555666 and the extension number is 255, the complete number is 01234555666,255.
Save the contact information.
The next time you call that contact, their extension number automatically dials when the call is answered.
