On a Family account, you can add up to 5 authorized users, plus a companion, for a total of 7 users. You may add more for a small fee (View Fees Schedule).
You can add children under the age of 18 who have a separate, unique email address (phone number and a smart phone is optional). The email can be a parent's email address, but not a parent email that is already connected to a Qube account.
In a Family account, you can also add adult children over 18, and other adults like grandparents or nannies. They will need to have their own smartphone and mobile number, and have a separate, unique email address.
Follow these step-by-step instructions to add a child to your Family account.
