I have an iPhone 5S. My husband has an iPhone 5S. I also have VZW Message+ on my Windows laptop and on my iMac desktop. For the last several days, I have had intermittent problems with my text messages. For example, I sent a text to my husband's iPhone earlier today. He received it and sent a response. His iPhone shows his response was "delivered," but it never appeared on my phone or on either computer. (Yes, iMessage is shut off on my phone.) Anyone else having the trouble? Can anyone suggest a solution?
