Understanding Charges on Your Phone Invoice at PhoneBox

Below is a clear breakdown to help you understand why certain charges may appear on your PhoneBox monthly plan invoice 

Interest Fee

An interest fee of 2.75% is applied if your previous invoice is not paid by the due date, which is the 25th of each month.

Example

• Invoice issued: May 15 – $35+tax
• Payment due: May 25

If the payment is not completed by May 25, the June 15 invoice will include a 2.75% interest charge on the overdue balance.

Reactivation fee

A $20 + tax Reactivation Fee is applied when your account is restored after being suspended due to an unpaid balance.

Example

• Invoice issued: May 15 – $35+tax
• Payment due: May 25

If the invoice remains unpaid until June 1, your line will be suspended. Once the outstanding balance is paid after June 1, your service will be restored.

On the June 15 invoice, you will see $20 + tax Reactivation Fee.

Plan Adjustment Fee

A Plan Adjustment Fee appears when you change your plan and the new plan price differs from your previous plan.

The adjustment may appear as a credit (minus amount) or a debit (additional charge) depending on the price difference.

How to change your monthly plan

Example

If you requested a plan change from a $50 plan to a $35 plan on May 20, the new plan will become effective on June 2.

On June 15, your total charge is $20 + tax.
