WHY is 5G connectivity so (Trash) unreliable on the T-Mobile network including their MVNO’s?!

I'm guessing you have never heard of RCS.  Apple will finally be catching up with this by it finally being added to iMessage.  Have you thought that it might be the device you are using?  I easily pull 300Mbit down and 150Mbit up in and around Hampton Roads and heading north, like Gloucester, has speeds upwards of 1Gbps down and 300Mbit up.  In Charlotte, speeds are always well over 300Mbits down and 100Mbits up.  Philadelphia has always had exceptional service in and around the airport with speeds over 500Mbps down and 100Mbit up.  I am using an s23 Ultra and have been since it was available to order.  

iPhone’s older than the 15 primarily use Intel models, which are not great for reception in areas where you might not be close to a tower or in very dense concrete jungles like New York City or Los Angelas.  

Have you considered replacing your SIM to rule that out?  Have you performed a network reset on your device after having Support perform one on their side?  

LMAO! Why is reading comprehension so poor in this country….hopefully  my initiall response is posted..
