iPhone 12 Pro - Call Failed - Verizon

I am sorry you had to completely wipe & restore. We're having the same issues...only seems to be with iPhone 12pro. I can't even call anyones customer service if it's a toll free number. Waste of $1k for this hunk of metal. I'm going back to my iPhone 11.

Believe it or not, this is happening on AT&T as well. I called them four times telling them that I am unable to receive phone calls. They offered me a new SIM card, several solution attempts, and nothing.

I was on this site looking for info to fix my 12 Pro on Verizon because I was getting the "Call Failed" msg. So after 10 minutesc of reading thru this, my phone magically started working again even though I doing change anything. Hope VZW and the 12's don't have some problem between them.

How do you know it is the same issue with T-Mobile? Is is actually T-Mobile or with the Sprint towers? I have AT&T and I'm not seeing this. The only person I know with T-Mobile who has an iPhone 12 is not seeing it but they didn't come in from Sprint.

I have been with tMobile for 5 years. Just 2 days ago upgraded to 12 pro max. Can’t call out or in. Followed all reset, power off, os update, etc. still not calling in or out. Same exact issue with wife’s new 12 pro max.

Your old plug and cable is certainly compatible. And there are very few first time iPhone buyers who have never had any cell phone, and any cell phone charger made in the past 10 years will work with an iPhone. But if you have never, ever, had any product that required a USB power source you will have to buy one. There might be one or two people in the world in this situation.

My iPhone 6s came with a cord that had a USB end, an outlet plug that the USB end of the cable accepted and the other end of the cord went into the phone. I tried to take a picture of the new cord but it won’t allow me to post it. I took a closer look at the one end of the new cord and it not really shaped like the old camera plug. The new cord has more of an oval, symmetrical end that I have nothing that accepts it to plug it into the wall.

My plugs for my old units stopped working after a while and the cord wore out. I can buy a plug for $15 (right now I’m using the really old bigger, bulkier plug and cord that came with an old iPad but it charges really slowly).

To use the new cord the recommended adapter is the 20 watt or greater USB-C power source. This is the same type of power source all newer MacBooks and many Windows laptops now use for power, as well as most Android phones.

Check with any friends if you don’t want to have to spend too much for that adapter. If anyone has an iPad Pro , MacBook Pro, or had a newer iPhone that came with the usb c plug in instead of the old usb a plug they may have a few around. Otherwise if you have access to Best Buy keep checking their deals of the day. They have often had the adapters and the different cables on their deals of the day for pretty good prices. It’s how I got back up cables and the longer cables (all apple brand). Unfortunately this affects those that are new to iPhone or had not updated to newer iPhones when they switched to the usb c to lightening cables and charging adapters. I understand the idea Apple had but knew it was going to be a problem to those that don’t upgrade as often or don’t necessarily have the other Apple devices that use the same adapter.

The MacBook Pro (2020) comes with the 61 watt power source so the new cord isn’t meant for that one although it can be used. The one “meant” for that one is thicker but can be used on the iPhone. The one that is standard for the cable that came with the 12 series is the 20watt adapter which is $19.99 some places $16.99 Walmart....and if you trust eBay I’ve seen them as low as $7.

There is no problem using the cord that came with the phone with any USB-C power source, so the 61 watt is fine. You can even use the 13 watt that was recommended for the 11, although it will be a little slower. The USB-C standard means that if the plug fits you can use it.

If you have a computer with a USB-C port like the MacBook Pro you can use that to charge and sync the phone.

Thanks for persisting. I can’t believe Apple waited for the social media pushback to address this. I have also had problems with people not being able to hear me on the phone. I thought it was a reception issue, but now I know it’s not.

Apple, please get on this.

Why are you hijacking this thread? If you have the same problem start your own thread and title it iPhone 12 Pro - Call Failed - AT&T to avoid confusion.

And you are only the 3rd person here to say you have it with AT&T. Two others have said they aren't having the problem with AT&T. Have you contacted AT&T? Are you using a new SIM or did you move the old one? Post this information when you create your own thread.

In response to @deggie — Wow! How rude. I was responding because I came here to see if there was a solution to my problem. Did you respond to bkyne or ChrisJ4203 in kind?? I made a simple statement to mainly respond to them. It would seem that it is only a Verizon problem but it is not. It seems you are the one getting extremely defensive and hijacking a post, which was not yours to begin with.

I apologize to everybody else for having to scroll through this. Apparently my first 11 words out of 8 pages hijacked a whole post.
