Rival carriers aren't too happy about AT&T's decision to raise the price on some voice and data lines for businesses.
Sprint is one. The Overland Park, Kan.-based company says AT&T's move is anticompetitive. Sprint filed a complaint with the FCC, according to the Wall Street Journal.
AT&T told customers it would stop offering extended contracts and discounts to companies that use special-access lines, which are high-capacity connections.
Sprint is among a range of companies – from telcos to banks to retailers – that buy these connections from AT&T and Verizon, which own the lion's share of special access lines.
"These steps are necessary to accomplish a smooth and non-disruptive modernization of our network and services," an AT&T spokesman told the Journal.
"It puts the rest of the wireless industry at a competitive disadvantage," responded a Sprint spokesman.
