Yes, and in new build homes and flats with the metal foil backed insulation in the exterior walls, you can have strong signal outside, and nothing indoors. WiFi calling is the only option.
Vodafone will still sell you a SureSignal box (femto cell), but the other networks might loan you a femto cell for a short time until coverage improves, if you are a "valuable" customer (ie, high spender). WiFi calling should get rid of all of this nonsense.
Much of the problem is Google didn't build standard WiFi calling or 4G calling into base Android, so each manufacturer handles each network settings differently. Apple built it in, so the individual network "carrier bundle" that is downloaded configures the settings.
The ancient iPhone 5s manages WiFi calling on EE and Three !!
