Hello,
Do you use several numbers and they are listed on the same invoice? You can then choose which will be the main number of your account, that is to say the one with which you will have full access to your customer area, and to electronic invoices in particular.
The main number is also the one on which you receive text messages that warn you that your budget has been exceeded. If your children are also BASE customers under your customer number, it is therefore recommended to define the number of one of the parents as owner.
The person who is currently defined as holder can make this modification on 'My data'. Select the desired GSM number under the 'User data' menu. Click on the 'Configure as owner' button.
thanks
