Wasn't even looking for this but just kind of stumbled upon it. Found the 32 GB Apple Iphone SE in a mass Walmart for $99. This is prepaid for Verizon. As far as I know, these can no longer be unlocked out of box (Since July 2017) by putting in another SIM but maybe someone else can chime in on recent experiences. You must buy prepaid and a) have it activated for 6 mo's or b) prepay minimum of $150 on it before it can be used on other carrier.
Alot of phone for the price. As always this is in store Walmart and YMMV.
