Hello, I too am new to this forum.
I have also been having this issue with a Note 8, from T-Mobile. Not an unlocked version. With the brand new SIM card I got with the new phone.
I have switched the to stock messaging app and have cleared all cache files, updated everything and this is still a problem. It mostly happens (that I know of) from group messages.
I had the same issue for a year with my Note 4 and T-Mobile was never able to figure out the cause or fix the problem. I upgraded to the Note 8 and its gotten worse.
I have gone from missing a text here and there, maybe a couple a week to now, huge chunks of group conversations. The people in the group's also have iPhones, Android phones, Samsung and nexus phones.
It's so frustrating, I'll be sitting next to my wife and she'll get messages in group chats we're both in, that I never get. She's on T-Mobile with a Note 4.
I have been on the phone with T-Mobile 3 times this week and so far they have been no help.
If anyone has had any luck with this issue, I'd love some help.
I should also point out that after reading what some of you said, I called T-Mobile back and asked them if I needed to change my sms address and the kid didn't seem to know what I was talking about.
He said he put in a complaint, which would escalate it to engineering and I should hear back in 48 to 72 hours. This is also not the first time I've heard this.
If it was happening on another phone it sounds like a server side problem and there is nothing you can do. Read up on your consumer rights and see if you carrier is failing you.
