Hey there I was told you would not by my carrier and Samsung. They were wrong.. You can't with the google map navigation because it downloads off their server. Download an alternate GPS program. I use either NAVFREE or Route 66 GPS navigation. They download the maps directly to your phone, which allows you to use your GPS without DATA usage. If you have an issue connecting to the GPS signal, I use a program called GPS Booster and it works to get the GPS signal.. When you use it just remember to disable your data network so its not using up your plan...
any questions email me ..
