Who I have the same questioned this topic

In the last few weeks our LTE signal has gone from OK to REAL bad. I’ve re-started my I phone 8. No help. Don’t have time to get in a phone tree situation that is non- productive to only leave mad. Ready to move to ATT as their service seems to have gotten better in the area (work phone getting better reception). Is there any hope, or should I just bounce after 100 years with Verizon?
