Beginning on May 1, 2013, AT&T wireless customers will see a new 61-cent monthly administrative fee on their bills. The new Mobility Administrative Fee applies to consumer and Individual Responsibility User (IRU) lines. The fee appears with taxes and other surcharges at the bottom of a phone bill, beneath the service charges. In contrast, Verizon Wireless has lowered its administrative fee 9 cents or almost 10%.
