Verizon shared plans back in February for a future change that involved SIM locking of their phones. The news made headlines because for one, Verizon doesn't lock their phones and hasn't for years (unlike other carriers), but it also was a significant change because they aren't allowed to lock them. I'm not kidding with that. FCC rules they agreed to as part of their purchase of Block C spectrum prohibited handset locking.
We were told at the time of that reveal that we'd get a clearer outline of their planned changes once they rolled them out in the spring. If you've looked at a calendar recently, then you know that summer is almost over and fall is upon us. We are well past any sort of spring rollout of a policy change. We have no idea what Verizon is doing with the SIM locking policy they first shared back in February.
