i am new to all this downloading to phones,i got this phone which is great,i am on 02 network,i went on to google play apps and downloaded games that said they were free to my phone,i was at home and i put my usb cable in from the phone to the computer,.i got my phone bill from 02 and it had trebled,i asked them why,they said because i have been using the internet on my phone,i am baffled,i thought as i used the cable and i was at home and the apps said free,that it would be free 
i am totally lost lol
i can not afford to change my tariff to one that includes internet,i love the one i am on,but it looks like this kind of phone will be no use to me as i cannot afford to download games,where did i go wrong
seemingly once the game is installed i can turn off WiFi and play the game without it costing,but i am now nervous of doing that in case it does cost to play once downloaded
i hope this makes sense to people
i would love to be able to play games on my phone when i am a passenger in a car etc which is why i got this type of phone,but now i am thinking i might as well sell this phone and just use a basic phone again
thank you in advance for any responses
