Regional carrier Cellular South has announced the launch of a new unlimited voice plan for $59.99 per month, with each additional line under the plan being an additional $29.99 per month, totaling $89.99 per month for two lines. The carrier also claims that its new plan is $10 cheaper than competing plans from the major carriers for the same level of service, despite T-Mobile offering unlimited airtime for the same price and the second line being $10 more expensive per month.
