There appears to be a bug causing a significant increase in dropped calls after updating to the latest iOS version.

Whether you’re looking for a reason to hold off on updating to iOS 13 or you’re looking for a solution after updating, here’s what you should know.

The Problem

In a nutshell, users running the latest versions of iOS 13 are seeing an increase in dropped calls. (In other words, a call cutting out and a “Call Failed” error message appearing.)

Users who are severely impacted by the bug are seeing a significant increase in the number of dropped calls and the bug may even be affecting their businesses.

Some users reported that their devices are “dropping calls like crazy,” while others suggest that the issue is “constant.” At least a handful of users report that “all calls” or “virtually every call” is dropped after updating to iOS 13.1.2.

The issue also seems to be related to signal or connectivity problems for some. Other users see their calls dropepd after about 15 seconds to one minute.

Some users have reported that downloading and installing the latest beta version of iOS 13.2 fixes the issue. But other users running an iOS 13.2 beta build are also experiencing a higher number of dropped calls.

This certainly isn’t the first time that users reported a surge in dropped calls after an iPhone or iOS release. While we can only speculate as to the cause, it’s likely something to do with the new software or hardware releases.

How Widespread Is This?

It’s not clear how widespread this problem is. What we do know is that it doesn’t affect every iPhone user, despite the prevalence of reports on social media.

With that being said, the problem does appear to impact users regardless of what devices they’re running. We’ve seen reports from users of models ranging from the iPhone SE to the iPhone 11 Pro.

Similarly, it seems like the bug is carrier-agnostic. While not every report included information about a user’s carrier, it seems like the problem is iPhone-based — rather than tied to a specific telecom provider or network type.

Of course, this information isn’t going to be useful to those who are already experiencing dropped calls. So let’s run through some troubleshooting.

Possible Solutions for Dropped Calls on iPhone

1. First thing’s first. We always recommend powering down or force restarting your iPhone before trying anything else. In a lot of cases, that could fix the issue.
2. You may also want to head to Settings > General > About to see if there’s a new carrier or cellular update. Installing that update may fix some connectivity issues, according to Apple Support.
3. Other users report success specifically fixing the iOS 13.1.2 bug by resetting their network settings. You can do that in Settings > General > Reset > Reset Network Settings.
4. If that doesn’t work, a couple of users have indicated that calling your carrier and requesting a “reset” and a new SIM card could put an end to dropped calls.

It’s worth noting that enabling or disabling Wi-Fi Calling doesn’t appear to affect the issue. You may still want to give it a shot to see if it mitigates the issue for you, however.
