We are overpaying for phone plans from Verizon, AT&T and T-Mobile. Budget wireless services, similarly fast and robust, can save thousands.
P.S. Some of the 'big' carriers, now and then, offer much less expensive 'plans'. Some event beat the prices in this article, if your 'Data' needs are limited.
My own experience.. Paying 200$/month for 4 "unlimited" plans on mobile. Switched to boost mobile aka tmobile and now pay $108/month for 4 "unlimited" plans. I would do it again in a heartbeat.
