Samsung A6 getting No Subject messages in group text
I bought a Virgin Mobile Samsung A6 that had not been activated before. I activated it about a week ago with Boost Mobile (Boost bought Virgin). After a few days, I stopped getting messages in group texts and started getting No Subject messages from individuals in the group. The No Subject message has a download button, but it won't download.
Also, when I try to send a message to the group, it won't send.
1-to-1 text still works fine and I'm in an area with good reception. Everything else seems to work fine on the phone.
