Copycat Carriers....

In a game of Tuesday-tag, Verizon Wireless (VZ) launched a $100/month unlimited U.S. calling plan. AT&T (T) was soon to follow. Not to be outdone, T-Mobile (DT) jumped on the bandwagon late in the day, and kicked in unlimited text and picture messaging. Shares fell. T -5.25%; VZ -6.6%; DT -2.6%. Sprint (S), the only major carrier left out (thus far) still dropped 3.55%. Besides each other, the group also compete with VoIP providers like Comcast (CMCSA) and Vonage (VG), who offer unlimited plans for as little as $25.
