Chosen Solution

I switched from Verizon to Tmobile, since I’ve done that my Note 5 is running slow when I try to send or receive text messages. I can’t receive MMS or group messages anymore. I tried downloading a new messaging app and the problem hasn’t resolved. My daughter who has a LG G5 is having the same issues. When I try to open a text conversation it flashes a couple time will either take a minute to open or go back to home page. Any help is greatly appreciated, please.

This has to do with the phones being verison and your carrier being T-Mobile https://www.youtube.com/watch?v=O2B3A_Sa… Thats the video for your phone.
