Solved! Our Verizon phones were getting no connection in our highrise


Update:

I ended up using Remedy 3 (scroll down for that). Also I noticed that when I do a system update on my phone, remedies 2 and 3 revert to the old settings. Annoying.

------------------------------------------------------------


We use Verizon. In June 2016, when we moved, one android cellphone never got a good connection. The others--two androids and an iPhone, got an okay, but sometimes iffy connection.

For the one that kept dropping calls incessantly, we got a landline phone that's hooked to a VOIP device that supports a Google Voice number. People call the Google Voice number, which then sends the call both to the VOIP and the cellphone.

But then, in March of 2017, the other androids started consistently dropping calls. Ultimately, there was one spot, one foot by one foot, where I could stand (not sit) in my apartment and sometimes not get the call dropped.

My 4G phone had one bar, even while I was sticking my hand out the window.

Then in May, I contacted the company called Smoothtalker about purchasing an extender. After some emails back and forth, in which he collected some good data from me, the owner recommended to me two devices, totaling $500. This seemed like a lot of money, so I started asking around.

A friend suggested that we contact Verizon before buying an extender. The Verizon rep said that the fact that it's a hi rise shouldn't matter, that we're on the 26th floor shouldn't matter, and the fact that many more people have moved in after we moved into the new, empty building, and the fact that the building is LEEDS certified shouldn't matter.


------------------------------------------------------------

Remedy 1

The Verizon rep suggested a setting change on each phone. I'll outline how to get to the setting on my LGG4, but it's similar for other phones:

settings-->networks-->more-->mobile networks-->system select-->network mode-->LTE/CDMA.

(You should see that the setting used to be Global; now you are changing it to LTE/CDMA.)

It seems to have worked. We spent a while on the phone with the Verizon rep using this new setting, which worked well, and then we did some experimenting with each other in the apartment, with one dropped call but we haven't been able to reproduce that error.

Interestingly, our phones still only show one bar.

Note: It is important to understand that travel outside of the United States or Canada will mean a temporary change back to "global" in the settings.

The rep did tell us that this change of settings will only work for android; not for iPhone, but we don't know if the iPhone is getting good reception, because the owner has been away a long time.

--------------------------------------------------------

Remedy 2


If we find that this change of setting is not good enough, then there is a second recommendation from the Verizon rep, which we haven't tried yet.  Leaving the new settings we already did, here are the instructions for the Glaxy S7 and the LG G4, which will likely be similar for other android phones:

Go into Settings-->Backup & Reset Network Setting

And she also said this second remedy can be done on the Iphone:

Go into General Reset-->reset network settings

Another note: One of our android phones is so old that it doesn't allow the second remedy (resetting the network connection). So to reset this phone, we will need to call Verizon and have a technician reset it from their side.

Remedy 3

I discovered Wifi calling, and my android supports it. Some iphones support it too.
Wi-fi calling


To change your preferred network on your Android device:
  1. Go to Settings on your device.
  2. Tap Network and Internet.
  3. Tap Advanced Calling.
  4. Tap Wi-Fi Calling.
  5. Tap When Roaming
  6.  Select the network you want to use while roaming: 
    1. Prefer Other Cellular Network
    2. (default) Prefer Wi-Fi.
