We encountered the same issue, where we were charged for incoming spam, robocalls, and texts. We contacted Verizon to dispute the charges, and they reduced our bill by half. We were informed that we should have put our phone on airplane mode to avoid these charges. I politely pointed out that this information was never communicated to us. It seems this is a recent change, as my husband has been with Verizon for years, and this is the first year we’ve received daily notifications warning us that we’d be charged $12 per day, but only if we used texts and phone calls.
