Verizon Galaxy S7 can't use mms on AT&T network.
I've contacted customer support and was told my unlocked Verizon phone will not send messages to more than one person and will not receive or send photos. Kind of limiting for text messaging.
Also, I can only get H+ speed.
Is new phone from AT&T the only answer or are the tech service folks working on a fix?
I have a friend with a Galaxy S7 from AT&T. We compared phones and he was getting 4G LTE and has no problems with mms text messages.
