I recently ordered an unlocked Android phone, a LG Optimus GT540. It hasn't arrived yet, thankfully I can return if this doesn't work out, but want to figure out something before I put in my sim card. I have AT&T. Is it possible to disable any and all data sending possibilities before putting in my sim card? For a while now I've been using a Nokia E63. A smartphone but once I got it I went in and removed all the apn information regarding AT&T's networks outside of the MMS information. I primarily wanted to use the wifi feature on the phone and had no desire to use AT&T's data connection or have a data plan. It worked and I haven't had any issues. If I do open a browser it ask me for a connection first (since I changed the settings). I figured I should be able to do that with any phone really but the Android OS complicates things a little. It tends to want to communicate all the time I believe. I found this after searching for a while. It was on this site. How to Turn Off and Disable Mobile Data Connection (2G/GPRS/Edge/3G) on Android Phone My Digital Life Will this really work to stop the phone from sending any data out? Not even a ping as they say? I have some dead zones where I work where no cell signal will get out. So I figure I could take the phone there once I get it. Switch over the card and then get into the settings and delete or alter APN information, etc. Though if there is a way to disable certain things before I even do that to just to make sure there is no sending capabilities at the time I'd feel a lot better. Is there a way to do it without any data connection being established? Or will this particular phone simply not pull the apn information over since it isn't sold in the US? I'm worrying over nothing? Thanks.
