I have been noticing increasing poor signal in my area, zip code 71411. This has been progressively worsening over the last year, including having issues with just not being able to access data without resetting the phone or going into airplane mode and back. This seems to work for a little while. I’ve also noticed at times I am unable to call and use data at the same time although this feature is on and I don’t typically have this issue in other areas.
