Extremely slow to non-existence cellular connection with iOS 12.4

I mostly use Wi-Fi, but I've noticed that when on cellular only, the connection is extremely slow if I can get a connection at all. I'm with AT&T and I'm getting 3 bars at 5GE. I've contacted AT&T, spent about an hour with them on the phone, but no difference. This became really bad around the time I updated my phone to iOS 12.4, but I'm not sure if it's related since I'm mostly on Wi-Fi and noticed this probably 7-10 days after updating to iOS 12.4.

Any one else getting bars but also getting No Internet messages?

Thanks.

I don’t recall exactly when iOS 12.4 came out and that wasn’t the main point. As as I said I mostly use Wi-Fi (like 95% of the time) and since updating to iOS 12.4 I’ve been having this problem.

It was a reasonable question, because if the problem occurred 7-10 days ago it clearly had nothing to do with iOS 12.4.

What troubleshooting have you done so far? Here's a list of standard troubleshooting steps to try:

Restart your phone-->Restart your iPhone, iPad, or iPod touch - Apple Support
Check for a carrier update-->Update your carrier settings on your iPhone or iPad - Apple Support
Settings/General/Reset - Reset Network Settings - you will have to re-enter Wi-Fi passwords, but won't lose any data
Restore iOS from a backup-->Restore your iPhone, iPad, or iPod touch from a backup - Apple Support
Restore iOS to factory settings-->Restore your iPhone, iPad, or iPod to factory settings - Apple Support

Hi lawrence, can I ask? My iPhone got a no service on July 22 afternoon (which is when iOS 12.4 was released) but at that time my iPhone was still on iOS 12.3.1. on July 23 I updated and I got a no service until now. Is it because of iOS problems?

I found a solution to my problem. While I had rebooted the phone (iPhone X) multiple times and reset the network settings a couple of times, it wasn’t until I did a HARD reboot that the problem went away.

On an iPhone X you do a hard reboot by...

1) press and release the volume up button

2) press and release the volume down button

3) press and hold the sleep/wake button until the slide to power off option is available

4) slide to power off the phone

5) power it back on as you normally would

Once I did this the cellular connection was back to normal.

iOS 12.4 was released on July 22, 2019; 4 days ago. ".....this probably 7-10 days after updating to iOS 12.4."

Seriously? 7-10 days after?
