I have a Samsung and my kids have apple phones. All three of us are having issues with sms, mms, and group texts. Not with just texting one another but with anyone or everyone. Most of my group texts or mms either won't go through at all or sometimes goes through hours later. My daughter can not receive any mms from me, no longer can text a few of her friends, and can't participate in any group chats. My son has many of these issues as well. I've done everything you can do with settings in each of our phones, you name it, I've tried it. I even saw on here to go into each line and go onto blocks and toggle that off then back on. Still nothing. I can only assume it's a Verizon issue?? It's been an issue for a month or so. How do I get this resolved? Do I need to just switch carriers at this point? Is this a known issue?
