Iphone 15 Pro going SOS frequently

So I have Verizon and I got an Iphone 15 pro over christmas. I am having an issue where when I am on the bus or train or car in my city (I live in Chicago), my phone will drop service and go into SOS mode for about 15-20 seconds then return. It has even happened a few times when I am just walking faster than normal. I am fairly certain it has something to do with my Esim and if I move faster than walking speed as it only usually happens when I use transportation, and it happens more on the bus, as the bus makes frequent stops and I noticed it happens more when I change speeds. I have found some people on reddit with similar issues but no fixes seemed to have been found. I stopped by the Verizon store and the person I spoke to also is having issues but with AT&T and other carriers, and said they went to the apple store and seemingly other carriers have an issue too and all with the Iphone 15. For possible fixes I have tried I have reset my network settings, turned my cellular line on and off, and yes I am on the most up to date software. I have done everything minus a full restore from back up, which I most likely wont do as the people on reddit with the same issue I have claimed it did not work and that takes up far too much time. Has anyone else experienced this, and if so are there any known fixes? Is this an IOS problem or a carrier problem? Is apple aware??? It is not the biggest issue but it is very annoying as I use public transit pretty much every day, and this issue has been persisting for almost two months, and the few software updates haven't seemed to address the issue.
