I bought a 4G SIM activation kit on the advice of a CS rep, who said I could change out the SIM card on my Verizon Droid X (currently in use with a customer loyalty plan) and switch it to a prepaid plan. But now it appears there is no SIM card to switch out. Google search finds several others have asked that question and the Droid X doesn't have a SIM card, apparently. But, the 4G SIM activation kit "Compatibility" tab claims that it is compatible with the Droid X, so what is the real story here? Do I have to send this kit back to you?
