CUB released a study by research firm Validas on Tuesday, which estimates smart phone users overspend about $194 a year on data usage.
The watchdog group recommends some tips to lower your cell phone bill: downsize to a lower plan, don't use unnecessary apps that drain data and investigate other ways you could be over paying.
"This analysis covered data only,” says CUB Media Planner Patrick Deignan. “It did not cover other notorious charges, like bloated calling and text plans, expensive extras and potentially fraudulent cramming fees. Make sure that you read your bill each and every month, scan it for charges that could be inflating it further."
CUB and Validas also recommend using Wi-Fi on your smartphone.
