Nice breakdown of equipment subsidies above. If you want an idea of ting pricing look here.
It doesn't give pricing but you can put the above scenarios in there to see where it falls. Not included in the calculator is the cost of the device which you must but up-front. Prices are better than the retail price from company stores but higher than the subsidized price from stores. I am trying to give as much info as I can without giving info that I am not supposed to.
Search youtube for ting mobile pricing.
