UNABLE TO CONNECT, CALL DROPS, POOR CONNECTION - WHILE ON WIFI

This (Edited per community guidelines) service has only gotten worse. Seems to occur in the late afternoons. Suspect when traffic increases (less bandwidth). Not my ISP. Reset Network Settings does NOTHING. Can't even make or receive calls, it just hangs and then drops ("Call Failed"). Made many complaints to AT&T AND ZERO IMPROVEMENT. Even when the call connects, the call won't last without dropping. Problem is not the phone. It's the service. I have a 5G phone, but there's no 5G service in my area.

The service is just awful. It is negatively affecting both personal & business calls. Intermittent periods where the audio will drop before the call fails. Then I can't get it to connect. Takes successive attempts before the call connects and shows on the screen though the receiving end reports seeing my incoming call. Toggling Airplane Mode doesn't seem to get it to reconnect. Brought up signal boosters before. I do not seem to have a problem with surfing the Web via WiFi, just the calls. Thoughts?

I tried to test signal strength but am unable to access Field Test Mode as indicated here:
https://www.waveform.com/pages/field-test-mode

There is no "Serving Cell Meas" and everything under the LTE section is unavailable.

The options can change with updates to the iPhone. I can access the FTM on my iPhone 12 (iOS 14.8) but the Service Cell Meas has been changed to something else. Besides, the info given is just a guide. Even if you can get information that is understandable to you there is not much you can do. It could be that your local tower is a shared tower so that the direction and intensity of AT&T's signals is not pointed in the direction that is going to give you consistent connectivity. Service area maps, by any carrier, are a bit misleading because all they can tell you is that the carrier's signal is detectable in a given area, it has nothing to do with the quality or reliability of the signal. You could just be in a shadow area.

I just upgraded to iOS 15 and they changed the FTM configuration completely again. I will need to call ATT direct. Hopefully someone can help.

What do you hope to accomplish with signal strength? If it's your service area, there is nothing that can be done until if, and when, AT&T is allowed to increase signal strength and/or propagation.

I am going to trial this signal booster and see if my call drops and connection issues stop. I would think the FTM would help me see the difference in the signal?

Which signal booster? If you're considering a signal booster, I'd suggest reading my Signal Booster Guide, the link is in my sig line. It is a little dated in that the FTM is not accurate anymore but it is a good primer on the various signal boosters, what they can and can not do, and how they work.

I got a weboost Home Studio. If it does nothing, I can return it.

Weboost is one of the mfrs' mentioned in my Cellular Booster Guide. You do need at least one, and preferably two bars of consistent signal strength for the outside antenna to lock onto and then transfer the signal to the indoor antenna. It is is DIY install but if you have it installed by a Weboost trained installer, they will use test equipment to determine which bands, strength, and propagation you are getting from the closet tower to you and correctly situate the outdoor antenna for optimal use.

So the FTM only shows the fixed cell signal from the tower, correct? Outside of hiring a technician, is the bar strength the only way I can then determine whether the booster works or not? And I assume, since the booster works off broadband, I need to disable the WiFi-C for it to work, correct? I still don't know the difference between Wifi-C and broadband. Do they work off the same cell tower?
