So my daily driver is actually an android, but a while back I picked up a cricket branded Lumia 640 for messing around with. I know that the W10 update is supposed to be available for it, but it never seems to update on wifi. Do I have to have a sim in the phone to get the W10 update? Is there some way to force the update? or is the update for some reason not available on the cricket variant?
