Consumer Action identified five ways that consumers often inadvertently spend too much money on cell-phone service.

1. Early Termination Fees
2. When you buy a new phone, perhaps because an old one was lost or stolen, operators typically they are required to start a new contract.
3. Some operators charge $.40 to $.45 per minute for calls that surpass a users monthly allotment for a postpaid plan.
4. Excessive text messaging charges.
