How do I know if my Samsung smartphone or tablet is connected to the internet?
A data connection comes at a cost. The contract you have with your network operator may allow a certain amount of megabytes of online transfer (typically 250, 500, 1000), after which you have to pay for every megabyte transferred beyond your allowance.
