Why do I have to pay at least $10 non-plan calling prepayment at signup for local and toll free numbers?
In order to keep the billing process simple and make INX service easy and inexpensive to use, we charge $10 to maintain a long distance account prepayment for non-plan calls. This prepayment covers all long distance for the local and toll free plans and only international for the unlimited plans. Whenever that balance is depleted by additional domestic or international calling, we will charge you credit card accordingly to maintain that balance and pay the monthly service fee. You can also increase your balance online to meet your calling requirements and monthly fee.
