OO Phone app for iPhone and iPad

OO Phone

OO Phone is your iPhones best application for smart and low cost international phone calls. It can save you as much as 98 percent on your international calls.

All international phone calls made from the OO Phone keypad will automatically be made on local phone numbers. So, from now on you dont have to sit at your office phone or a computer to make international phone calls at a reasonable cost!

This is how it works:

1. Install OO Phone.
2. Call to any number from the applications keypad.

The application is ready to use instantly. Your phone will dial up a local (national) number and then automatically connect you to the international one. This is possible without the need of Wi-Fi or other data connections.


How to call

1. Call to any international phone number from the OO Phone keypad.
2. Your phone will dial a local (national) number and then automatically connect you to the international number you dialed from the keypad.


Faster ways to call

There are two ways to make it easier to call phone numbers that you call more frequently:

- Save your friends names and numbers in your Operator One contact list and call them from there.

- You can choose to have your iPhones phone book synchronized with your Operator One contact list. This means that all Operator One contacts are added in the iPhones Contacts, as separate entries with "OO" added in front of their name.


Add credit

From the Add credit tab you can add call credit to your Operator One account.


Coverage

The app works from 38 countries and you can call to any country in the world. Your friends do not need to have the app installed.

If you regularly travel and have local subscriptions (SIMs), OO Phone supports up to 10 different phones to call from, using the same account and credits.
