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.

@Constructive "The easiest way to check is to run a Speedtest on Speedtest. Net. It will say in the results if it’s a business account." 

Good tip. I didn't know that as I've never had a business account.

@OttoPylot  i didnt know they set mine up as a business account until i was banned from the battle net servers and they told me it was because i was using a vpn or on a business account, well i argued saying i was using neither. they suggested the speedtest and sure enough is said business account

With no other options to improve connectivity and signal strength from my calling area, I am looking at signal boosters. Anyone with experience? I used the old AT&T MicroCell signal booster towers back in pre-WiFi-C days and still had terrible service. I'm hoping to find one strong enough that can grab a 5G signal. WiFi-C just isn't good enough and the towers seem to get congested intermittently during business hours.

I have a signal booster in my car. Last time I looked at the Weboost website there are no signal boosters for 5G service.

The Signal Boosters that are out there boost common LTE and 3-g signals.

Since voice service is carried over the LTE network boosting 5G would not help you, boosting LTE signal would.

Yes, am connected to WiFi calling as is indicated in the settings on the iPhone 12 as "Wi-Fi Calling on This Phone" slid to green.

I know you posted this days ago but having Wifi calling enabled does not mean you are actually connected to WiFi calling. Again, you aren’t connected to WiFi calling unless you see “AT&T WiFi” as the carrier. Did you ever try airplane mode to force your phone to WiFi calling? You should also try WiFi calling from a different WiFi.

@mcs2015 For clarification, the MicroCell is/was not a cellular booster. It was a femtocell that broadcast a 3G signal that your phone locked onto and then the MicroCell used your internet connection to reach the AT&T Mobility Servers. As far a cellular boosters in general, see my Cellular Booster Guide for a primer on what they can and can not do, installation, etc.

WiFi Calling (WiFi-C) is what is recommended now for improving in-home service. Your line needs to be provisioned for WiFi-C so if you have WiFi Calling enabled on your iPhone 12 (I have one as well), and the alpha tag indicates AT&T WiFi as indicated by @sandblaster then your are connected to AT&T. If not, the cellular signal could just be strong enough so that your phone will connect to that. And as you walk around your home, the signal strength may change between cellular and WiFi which will result in dropped calls. There is no way to set the phone to always pick one over the other. Turning on Airplane Mode as suggested, may be one way to force the issue and if that works, you're fine, until next time. WiFi-C is totally dependent on how robust your WiFi connection is. It is similar to the MicroCell in that it uses WiFi, instead of a 3G signal, to reach the AT&T Mobility Servers via your internet connection.

Have been trying turning toggling on/off Airplane Mode when unable to connect the call and in most cases, was able to get the call to connect. Just curious, why Airplane Mode?

@mcs2015 Airplane Mode disables the cellular radio so that your phone can only connect thru WiFi-C if you have set it up.

So, turning it on/off re-enables the cellular radio I assume?

Yes. That's why when you're on an airplane you're asked to place your devices into Airplane Mode so that your cellular radio doesn't interfere with the plane's communications while taking off and landing.

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.
