Orange is a U.K.-based line of pay-as-you-go mobile phones and cellular devices. These mobiles allow you to have access to a hand-held device without having to commit to a long-term contract. With your Orange phone, you can check the balance of minutes remaining in your pay-as-you-go plan by dialling a number on your keypad.
Switch your phone on by pressing and holding the "Power" button.
Enter "453" on your phone's keypad.
Press the "Call" button on the keypad. You will be directed to an automated message telling you your Orange phone balance.
