How can I stop my iPhone 16 Pro Max from dropping calls?

I have turned on AirPlane Mode and turned off.

I have turned phone off and on.

I have WiFi calling on.

I am on 5G standard.

I've been troubleshooting an issue for a few days where calls were constantly dropping with Wi-Fi calling enabled. Neither Apple customer service, nor my cell carrier (Consumer Cellular) could provide any useful help. However, after extensive testing, I believe I’ve identified a solution.


Quick Fix: Turn Off 5G Auto

  1. Go to Settings > Cellular > Cellular Data Options > Voice & Data.
  2. Select either 5G On or LTE, depending on what is available in your area.


This adjustment should allow for a seamless transition between Wi-Fi calling and your cellular network.


My Experience

iPhone 16 Pro iOS Version 18.2.1

With Wi-Fi calling enabled, calls would drop if my Wi-Fi connection dropped. Similarly, if I was on a call with Wi-Fi calling disabled, then enabled Wi-Fi calling during the call, the call would also drop. I have cell reception with 5G and LTE in my area, so I knew that wasn't the issue.

After switching 5G Auto to either 5G On or LTE, this was no longer an issue and calls no longer dropped. Interestingly, after making this adjustment, I reverted to 5G Auto, and the problem seemed resolved for now. It appears there is likely a bug with the 5G Auto setting that is causing the issue.


Please let us know if this helps you and hopefully this will help other frustrated iPhone owners.

I had a iPhone 16 pro max that constantly dropped calls for the past 3 months. Took phone into Verizon store and was given eSIM and old SIM card taken out. Calls continued to fail. Took phone back in and was told internal antenna was probably bad. Went home and ordered 16 pro max. Go it. Set it up. And dropped calls again. This is bad as I am handicapped and rely on phone for medical issues and etc… I tried all the responses on this page and then some. Anyone have any ideas. Need help please. Should i send new phone back. And I do have all bars in the house and Verizon wi-fi is strong. Bummed out in New York!!!!!!

iPhone 16 Pro Max. Dropping calls. Can’t carry a conversation because the other person on the line hears a garbled mess.

Have made numerous calls for support tried all the fixes and nothing has helped. This phone cost too much not to able to make a calls. If the issues are not fixed soon I will be taking it back and trade it in for an Android. My husband has an android and he has no issues.

Which I will lose my itunes but I have to be able to make calls. I have always had an iPhone. Bye Bye Apple.

iPhone 16 pro max several months old. This has been happening to me the past two weeks extensively several times a day. All the updates are done, network settings reset. Happens on at and t and WiFi equally.


it’s got to be a hardware issue. I dread bringing this to attention of Apple or carrier bc they will try and tell me to do a clean install which won’t work but will take hours.


any advice would be appreciated
