I pay $100 / month for unlimited LTE for both my wife and myself via T-Mobile. That comes with free international data roaming as well.
As for Prescription prices... it is really hard to say since everyone has differing insurance coverage. The insurance companies gladly pay exorbitant fees for the drug prices (keeping them high) because they know that lower drug prices would mean many people would choose lesser insurance options.
In my case, my employer and I share the cost of my health insurance. The types of prescription drugs I buy at my age are very very cheap under this coverage. $5 out of pocket at most for common things. Of course.... like I said, behind the scenes, my insurance is paying huge amounts for this. For someone paying cash the price would be much higher.
