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.
I've had ATT prepaid for me and the other 3 in my family and with all of us it's about $100/month. We don't need unlimited since everyone is almost always connected to wifi. Also they roll over unused data up to 30gb. The wife and I have 25gb plans and the kids have 5gb plans and we can use those for tethering too. Been on it for over 4 years now...
