Plans could be expensive these days, from network to network. After doing some research of my own. Look what I’ve found!
I. Skype is offering really cheap unlimited calling from $2.95/ a Month (U.S/Canada) also International Unlimited plans.
II. To use Skype you will need a Internet connection, and you could get a Mi-Fi from Verizon or Sprint and pick one that fits your budget.
III. Text? Use Google Voice. Free SMS, no MMS support just yet.
