How would I go about using my Droid X2 as a Wi-Fi only device? I want to downgrade to a 'dumb phone' but yet I would still like to keep the Droid X2 to play games, browse the Internet, etc. all over a Wi-Fi connection - essentially use it as a tablet.
Just activate the basic phone on your line. This will automatically de-activate the Droid X2. You should still be able to use it as a wi-fi only device.
Be sure to log into your MyVerizon account to confirm that you no longer have a data plan associated with the line. It should be cancelled when you activate the basic phone, but you should check just to be sure.
