How to Add a Line to Your PhoneBox Account to Manage Your Family Member's Plan

Step-by-Step Guide to Manage Your Family member’s Line Under Your PhoneBox Account

• How to add your family member’s account
• How to switch to other accounts under your account 
• How to delete a line under your account

If you have more than one PhoneBox account that you would like to merge into one, you can use our [Manage Child Account] feature available on both our website and mobile app. This feature allows you to easily add or remove lines using a secure OTP verification process.

With this feature, the primary account holder can easily switch between linked lines without logging in and out of multiple accounts. This allows you to conveniently check data usage, manage payments, and perform other account-related actions for each line from a single login.

What are the benefits?

1. Better Control

• You no longer need to log in to each account individually or contact customer service to make payments.
• Users can easily toggle between the accounts, allowing for a complete view of all active services in one place.

2. Peace of mind

• Each line user can still log in to their own Self-Serve account independently.
• Even if billing responsibility is transferred to a parent, family member, coworker, or friend, each user retains personal access to their own account information.
