Samsung GT-S5839i

you can download a app to stop all unwanted internet traffic

I bought this phone 3 weeks ago, the first thing i found was it would not connect to the internet because it was set up for a foreign market. I got that corrected and then found that the phone used up my credit at the rate of about £1 per day even if i did not use my phone, i had to switch off packet data and some of the services to stop it doing this but with packet data switched off it will not connect to the internet so i have to switch it on to use the net. Altogether i am not very impressed with it and will go for something better soon.
