I have a IPhone 7 Plus unlocked and purchased from Apple and I am using Metro PCS. When I get messages from my answering service the messages will not group together. Instead there are random numbers in front of the senders name such as 416-9 or 398-0 and a bunch of others. So instead of reading messages that are grouped together or one continuous message a new message every time. It did not this with Verizon it only started when I switched to Metro PCS. Metro PCS told me they have no control of that and it has something to do with the sender. I contacted the sender and they basically say the same thing that they have no control of that. It only happens with the answering service all other messages group together. If is something that just cannot be corrected then I will live with it because I am very happy with Metro PCS other than this. I have tried turning off I messaging and creating a VPN but neither worked. Thanks for any help you may have.
