3g connection
My iPad connect only for 2g, I can't connect to 3G , and when I remove the sim card to another iPad its connect as 3G, please help
iPad 2 Wi-Fi + 3G, iOS 5.1.1
Settings > General > Reset > Reset Network Settings,
After you've tried that (and you still aren't connecting to 3G) you may need to restore the iPad to factory settings.
