Text messages are randomly delayed by up to a day

when it seems like you havent received any texts in a while try texting yourself to see if it comes right through or if its delayed..helps rule out the problem being on your side..at least with sms...to test mms send youself a pic and see how long it takes to come through...

the delayed texts coming in...are they usually delayed from a specific person/people in the group or is it a bit random? could end up being the relay from one carrier to you that has the issue as well..kind of a hail Mary but cant exactly rule it out either.

one other thing to do would be a network reset..your phone might say you have great signal but you might be hung up on a further out tower causing issues.

I've been seeing this off and on for months in group texts mostly, but also in direct texts as well. The problem is that text messages are often delayed by up to 24 hours and then dumped all at once into my phone. This is looking to be a TMobile issue. I'm on an iPhone 11 Pro with the latest version of iOS. To sum up:
This is only with text messages, not iMessage or other messaging apps.
This happens when I have a good signal and a wifi connection in my house, but it has also happened when I'm out and have only cellular, but still a good signal.
The other people in group chats are spread across numerous different carriers. None of them have reported this.
The usual phone troubleshooting steps (quit the Messages application, restart the phone, etc) do absolutely nothing.
I checked the activity logs in my TMobile account. The text messages in question all came through at the same time according to the logs. It looks like it's somehow getting delayed inside of TMobile's system.
I've missed some texts due to this that were relatively time-sensitive. I don't think I need to express my frustration at something as old and dead-simple as SMS/MMS getting screwed up like this.
It also doesn't help my frustration when the browser based Places/Topics Browser is hopelessly broken and the page I'm using to write this keeps auto-scrolling down when I interact with a number of elements on the page.
