Signal Decrease Last Month
I have been a wireless customer for about 5 years now, we have 5G coverage and it has been great. In the last month, I have had only one bar of 5G at home, and the phone will switch to LTE with one to two bars of coverage.
At work, I have one bar LTE and most of the time my text messages to do go through. Occasionally when leave work all of my messages come into my phone, other times nothing.
I have reset the network settings twice and the problem has not been corrected, the phone is an iPhone 13 Pro Max (at&t branded), and my work address is 2260 US-93, Kalispell, MT. 59901.
I contacted the COR store here locally, they are completely useless in regard to helping customers with network issues. I was a previous COR manager and we had the ability to network test areas with our company laptops and send information to the network engineers in Cerritos CA. Often they would complete an 'uptilt' to resolve, however, I am not sure what is done these days.
Help would be much appreciated, otherwise will have to port out to the evil empire (Verizon) which does not have 5G coverage in our city yet.
