Assisted Dialing on Android phones

Modern Android smartphones support a feature called Assisted Dialing. This allows the user to dial local telephone numbers using the normal local short dial string. For example a user can dial 0123456789 instead of +nn123456789 where ‘nn’ is the international dialing code.

Because our mobile service uses roaming technology it is important to disable AUTOMATIC Assisted dialing on your Android phone and actually specify the country in which you are located. Otherwise you will need to use the international dialing format ( +nnxxxxxxxx ) for every outgoing call – even for local calls. If you do not select the a specific country for national dialing and you dial local calls without using the international dialing format then your outgoing local calls will fail. You will get a voice prompt saying something like “This call cannot be completed as dialed”.

It is not necessary to alter the Dial Assist settings on an iPhone, as this uses a different method to determine in what country the user is located.

On an Android phone you can change the Default home country as follows:

  1. From a Home screen, tap Phone.
  2. From the Phone screen, tap the Menu icon Menu icon(upper-right).
  3. Tap Settings.
  4. Tap Assisted dialing
  5. Tap Default home country
  6. Select the Country in which you are located.
  7. If needed, configure the following options:
    • Reference country
    • Country code
    • IDD prefix
    • NDD prefix
    • City/area code
    • National number length
  8.  Powering the phone off then back on is recommended after changes are made
