iPhone 6 loses service

[Mg]

My iPhone 6 loses service when walking from one part of the house to another. In comparison, my iPhone XR Does  not lose service when walking from one room to another in the house. The Xr Has software version 14.7.1. The iPhone 6 has version 12.5.4 with no way, I can find, to update.    Is Visible telling me that I have get a new phone?  I hope not?  I don’t want to have to teach my husband how to work the newer iPhones.   Thanks for y’all help.
