With oodi, you can share data with a friend in less than 2 minutes. If both of you are oodi customers and have a plan, the data transfer can be done by scrolling down the home screen, and clicking on "data transfer". You can now select the amount to transfer (there is a limit of 5GB per 30 days) and the phone number of your friend. As soon as you validate, your friend receives the transfer! We told you, 2 minutes... Your friend will see the shared data in the booster allowance.
Bear in mind, that transferred data expires at the end of the recipient's current plan and that shared data cannot be transferred to another user.
