iphone 12 dropping calls

My iPhone 12 Pro has been dropping nearly all calls since receiving after launch. The tech said "Oh, the diagnostic reported 13 out of 18 calls dropped recently, so that's not good". I purchased through Verizon, and have since gone through multiple resets, SIM card replacements and phone replacement and still have the same issues. All of the support was through Verizon and ultimately Verizon said this was a known issue with Apple and that I should take it up with them. So I just finished testing with an Apple tech, after over an hour on another phone I had to borrow to get this addressed. The Apple tech took it to his level 2 who ultimately said it was a Verizon issue, without a doubt because there is zero chance 2 new phones would have the same issue. They then placed me on hold because they said they wanted to bring Verizon on the call because I told them Verizon said to take it up with Apple. The Apple tech gave up after 35 minutes of being on hold and said we could try again later. Ha!

So no one is owning this known issue and I am stuck with a $1000 piece of garbage. Never again! I am going to have to shell out more money to get another phone and I am absolutely dropping Verizon as well. I would really like to know through all of this, is there anyone with the new iPhone 12 that is not having any dropped calls?

We have iPhone 12 and 12 Pro Max both on AT&T and not a single dropped call yet since launch of both.

This leads me to ask those who are having dropped call issues the following questions.

Did you transfer the sim from your previous phone to your new phone? If you did, you should get a new sim which is provisioned for 5g
Go to Settings > Cellular > Cellular Data Options > Voice & Data - What is it checked? If you live in an area with minimal to no 5G service (5G is still rolling out across a lot of the world), and your phone is set to 5G, you'll drop calls. Change it to 5G Auto or if you don't have 5G where you live to LTE

Otherwise it seems from those posting here, the common issue is Verizon. You should be hammering Verizon on this as it's most unlikely an issue with the phone. The entity who controls calls on your phone is not Apple. It is your cellular provider.

Moving the SIM does nothing, the SIM just allows your phone to connect to the network, it doesn't define what kind of phone it is and what its capabilities are to the tower.

Your Android phone likely cannot use the frequencies misconfigured at the tower (or that are poorly received due to environmental or atmospheric conditions) so of course you would never see the issue with it.

It all works for your cell provider though, as they know you'll get mad at Apple, not them, and they don't have to spend a dime sending a tech out to the tower to correct things.

iPhone 12 dropping calls is a carrier issue, I think not!

traded phones for a couple days with a friend, same carrier but with Samsung and perfect performance with no dropped calls,

will be buying a Samsung next week, good bye apple.

My issue is with iPhone 12 on Verizon and on AT&T Wi-Fi here at house. All calls to/from my phone in house FAILED and ENDED. Go to another wi-fi carrier and calls in/out are fine. So my troubles lie with AT&T….

Do you have a new sim card in your iPhone or did you transfer the sim from your previous phone? You should use a new sim card, one provisioned for 5G in your iPhone 12.

Notify your carrier.

They will tell you they see no issues with their equipment and it's Apple's fault but it still counts as a logged complaint in their systems.

I have no problems when I’m exclusively on the cell tower. It’s when I am connected to WiFi. With WiFi calling on or off, doesn’t matter. The phone is the common denominator.

I’m with Telus and iPhone 12 drops calls as soon as I leave major city’s, rural areas don’t seem to have 5G or great LTE, iPhone 8 locked on 3G works great.

WiFi calling is a cellular carrier feature, and if they aren't handling the handoff properly, that's the fault of your cellular carrier, not the phone.

May 20, 2021 6:19 PM in response to Rjconn007

That's a handoff issue, which is a cellular issue. Wifi calling on both our iPhone 12 phones with AT&T works flawlessly.

May 24, 2021 6:44 AM in response to petemcl

Yes. On and off, but when off it’s a different problem, low signal. Which is why I use WiFi calling. Again, X,11, and 11 pro, no problem. Not the carrier if the phone can’t figure out which to use.

Contact your cellular carrier; something is going wrong on their network, your account may not be properly setup in their system.

Since you too have Verizon, maybe it's time to say goodbye to Verizon and go with a different carrier. You can't compare iPhone 8, which is LTE to iPhone 12 which is 5G.

Dec 31, 2020 7:47 AM in response to Shwnster

OK.....I'm not sure what your assertions mean here except you have Verizon, which is causing your issues. No one I know with iPhone 12 (any model iPhone 12) is having issues on other carriers. And Forbes has had a burr up its butt against Apple for some time, so I don't take anything Forbes says about anything Apple with anything more than a grain of sand.

I'm also so deep into Apple it would not make sense to get out of the system for anything else.

The other variable is Verizon. I’ve had no issues at all with my iPhone 12 Pro on AT&T.

You live near Chicago and you still have 3G as an option? What carrier do you use. 3G has been in the process of being shut down in the US for some time now. We haven't had 3G service in Tampa for a loooong time now. I can tell we are on AT&T, with two iPhone 12 (regular 12 and 12 Pro Max) and have zero dropped call issues.

What has your carrier suggested to help you?
