FIrst reported on our forums, Cingular is unleashing unlimited mobile-to-mobile text messaging within its network. The $5 add-on will enable Cingular customers to text message one-another without any per-message cost. The per-line add-on is now available, launching this morning, in all Cingular retail channels. Cingular will also promote the plan add-on as being integrated into their MEdia and business data bundles, at the same price-points with $5 options for M2M messaging across the board.
The only exception to this is the launch timeframe for business customers. While announced as being for both consumer and business customers, business customers will have to wait until March 11 to add the new add-on.
