zero bars at all times.

I have lived at my address since 2017. I have zero bars at my house at all times. If you want to make a call, you have to stand in the kitchen next to the window. I miss several calls daily. I have my settings on wifi calling. I contacted cricket today and they said the signal is good at my house. They suggest buying a booster. Is this my only option? Reviews are not good, hit or miss. I get all text messages that I am aware of. Any suggestions? I appreciate any feedback. Thank you.
