Rural booster issues

magenta5101762

    I live in a rural area with about 2 bars of signal in the best location in my house. I have a booster in that location and find it fluctuates between showing LTE (about 3bars on the booster) to showing 4 bars without LTE. I will switch my phones preferred network to WCDMA or 3G, 4G when the LTE light goes out. This will sometimes last for a day or more. My issue is that call quality is much better when LTE is not indicated on the booster (3G,4G only) and I'm wondering why I even need "VOLTE" in my home when my wifi router provides my data needs anyway. I would prefer switching the LTE off in the booster and have good call quality all the time.
