This is pure collusion, that proves that ATT and Verizon have no intent on competing. If this continues, market regulation or breakup may be required.
Raising the cost of data from $30 for 3GB to $40 for 1GB is a 300% price increase and unacceptable in any mature market. As unlimited text and calling plans become redundant to cheaper internet based services, the mobile companies are trying to lock in current income for specialized services people will no longer need.
AT&T and Verizon have developed these plans to protect themselves from the inevitable switch from charging as much as the market will bear for voice, text or data to all services becoming part of the data stream with the next evolution of LTE. These plans are an attempt to challenge the prospect that they may become "dumb pipe" providers of data in place of more expensive add on services.
Once voice calls are just data streams on the data network, the mobile providers will give you that data for free when using their services, as opposed to charging you for the data if you use skype or another ip phone system. They will still charge you outrageous foreign call rates and international roaming charges when ever possible. This would be a definite violation of network neutrality as they would be providing preferencial treatment to their own, non optional unlimited voice and text plans over competing internet services.
The new share everything plans acknowledge the diminishing importance of voice and text services, by requiring you to buy unlimited service and shifting the current fees for these services to the first GB of data.
Even though you some people may actually pay less under these new plans, they are designed solely to protect loss of income that will result when people no longer need high voice minute plans because the competing data based voice plans will be identical in delivery and quality to the mobile provides plans yet without added rates.
This is a strategy to increase data fees while delivery costs drop to further increase profits while fooling the public into thinking they might be getting a deal.
