Verizon bills are not set up to be split into multiple accounts. If you have a family plan, each person on the plan should have their own phone if they want to receive their own bill.

There are a few ways to do this. One way is to open the Settings app, tap Accounts and then tap Add Account. You can add your Google account, your iCloud account, or another email account.
Another way is to go into the phone’s Settings and tap Accounts & Passwords. Select the account that you want to remove and then tap Delete Account.

You can’t.

No, not really. There are some companies that offer this service, but it’s not the norm.

You can pay part of your phone bill by adding a credit card to your account. You can then set up an automatic payment that will deduct the desired amount from your account and transfer it to your phone company.

To remove a phone from your Verizon account, you’ll need to call their customer service number.

Verizon Wireless customers can transfer their current service to another Verizon phone by following these steps:
Sign in to My Verizon Account online and click on the “Transfer” button under the Transfer Service section.
Select the desired phone from the drop-down menu, enter a desired phone number, and click on “Next.”
Follow the prompts to complete your order.

Yes, you can keep your phone number if you leave your family plan. All you need to do is call up the company and tell them that you want to cancel your service. They’ll ask for your account information and then they’ll give you a cancellation date. You’ll be able to keep your phone number as long as it’s not on an old family plan.

No, it does not notify you when you leave family sharing.

Yes, you can split the ATT bill.
To split the ATT bill, simply divide it into two or more parts. You can either have one person pay for the entire bill and then have other people reimburse that person, or each person can pay their share of the bill.
