If your phone supports the pause function (which most iOS and Android devices do), you can create a contact containing your TTNC phone number and PIN code. Whenever you call this contact, the speed dial takes care of everything for you, so you only need to enter the number you want to dial.

Please note: the speed dial feature will only work on a handset that's been registered with a TTNC number. If you haven't registered your mobile, follow this guide to get set up.

Follow the instructions below to set up a quick dial contact on your iPhone:

1. Open up the Phone app and then make sure the Contacts tab is selected.
2. Tap the + icon in the top right corner of the screen.

3. Add a name and then tap the add phone link.

4. Use the keypad to enter your TTNC number.

5. Then tap the +∗# key to load up the special keypad.

6. Tap on pause and the keypad will revert back.

7. Enter your four digit PIN code.

8. Tap Done in the top right corner to save the contact.

To create a quick dial contact on your Android handset, just follow the steps below.

1. Open up the Phone app and then make sure the people tab is selected.
2. Tap the + icon in the top right corner of the screen.

3. Add a name and then tap in the Phone field.

4. Use the keypad to enter your TTNC number.

5. Tap the P(,) key. If you don't have this, then press the , key.

6. Enter your four digit PIN code.

7. Tap the Save button to save the contact.

With your contact saved, making a call couldn't be any easier. Simply call the contact as normal and, when prompted, enter the number you want to call.

Please note: as the service is automated, you will still hear the prompt to enter you PIN code. However, you won't need to do anything, as the PIN code will be entered automatically (you'll hear the key pad tones to confirm this).

Is there a particular number you frequently dial from your TTNC number? By expanding upon the instructions above, you won't even need to enter the number whenever you want to call it.

Follow the guides above, but once you've entered your PIN code, add another 'pause' followed by the number to dial.

Whenever you dial the contact, it will automatically call your TTNC number, enter the PIN code and then call the number.
