I've responded to similar questions in the past, so advance apologies to those who've seen my comments before a time or two.

Phone brands, and even different models within a brand, are not the same from one to the next. Sometimes even different individuals of the same model type on the same service will have different signal reception.

Carriers don't always have their individual antennas at the same location as others do. Signals from the same tower for the same service can vary from place to place.

The simplest and cheapest solution to this problem when you're home (it's free) is to put your phone on airplane mode, THEN turn on Wifi to connect to your home Wifi signal. Be sure that "telephone over Wifi", sometimes called "Wifi Calling", is enabled on the phone. Phones with this capability (most do) don't care what path signals to/from the carrier's home base take. You'll get phone, message, and data service on your phone of the same kind as if you were standing under a cell tower. Remember to reverse those steps when you leave home. If there are weak spots in your Wifi coverage at home, that's easy enough to fix and the benefits will extend to more than phone use.

A second approach that may or may not be free would be to get a Network Extender (not a repeater, which is an amplifier only) for your carrier. I have two homes where the cell signal is marginal because of hills. I complained and Verizon at two different times provided me two free ones that they otherwise sell for $250.. Network extenders are like having your own mini-cell phone towers, they send out a cell signal your phone will connect to. The extender gets connected to your home network and so sends traffic to/from your phone over your internet connection. For me, at both locations, unreliable 1 to 2 bar connections are now 5 solid bars throughout the homes and not less than 4 when outside. The setup is pretty easy and as Ron Popeil would say, "Set them and forget them". They require no further attention. When power or the internet signal goes down, they reboot automatically when it's restored.

A third approach is if you have a neighbor whose phone gets a strong signal in your house, buy that model and subscribe that service so see if it would work better in your home.

Good luck.

Thanks Elmer J Rudd.

We no longer use internet. Edu used it for recipes and I just plain used it less and less. As I mentioned in my prior post none of us her good reception and we each have a different server. Oh well... Might try the extender... Thx again. Now have to work on antenna tv! We both agree too much tv/internet has its own problems. But dang- tv sounds a bit more fun than this horrid heat this year!

The extender needs an internet connection. Instead, you might try a signal amplifier but these work much less well.
