The best way to save on your cell data usage is to switch your smartphone over to WiFi whenever you’re around a hotspot--unless you have a new iPhone 5
and are a Verizon
Wireless customer, in which case a glitch apparently caused some phones to burn through the customer’s data allowance when it was supposed to be connected to a WiFi network.
We’d rather not imagine how much money that has cost some people in overage fees.
The good news is that Apple
released an update--Carrier Settings Update 13.1--that should resolve the issue. Under the About tab under Settings-->General on the iPhone 5, users will be prompted to install the update.
It’s not clear if the glitch has affected iPhone 5s on other carriers.
