If I get an iphone from Sprint and were to use my samsung galaxys Wi-Fi on the iphone (lets say 99.9% of the time) will that save me money or are there like data usage fees for using Wi-Fi? And what about calling people while using this 4G mobile Wi-Fi… Is that possible or do you only have to use mobile data? I plan on getting the 80 dollars a month unlimited plan with Sprint by the way. If you have any tips and how to decrease the use of data on an iphone or what have you (if its the same with other phones) feel free to let me know.
