iPhone 12 Pro Max dropping calls and poor phone signal

Try turning off the Wifi and leaving it off. That seemed to work for me.

I've been having the same issue and went through some trouble shooting with Verizon but did not fix the issue. I have just tried something I found in a web search, which was to shut off the Bluetooth for a bit then turn it back on. Well I turned it off and made a few trial calls without the Bluetooth. Well so far that is working. Will see if that corrects the issue. I'm sure Apple is working on an update fix shortly. Fingers crossed.

Hello, I just purchase 2 Iphone 12 pro max 256gb on Dec 3. I am having the same issue. I took it into the Jump Plus store and they basically did nothing. I tried switching service providers from Fido to Telus and then back to Fido but still the same issue. Here is what I did to resolve the issue,

Open settings

Select "Cellular"

Turn off "Cellular Data"

Select Cellular Data Options"

Select Voice & Data and pick the 3G network.

Doing this gave me full bars within a few seconds and it is still working well.

Hope this helps, please let me know if this works for you.

Got my 12 Pro Max on black friday (yeah, I'm ignorant, thought I'd get a deal at Verizon..lol). Anyway, worked great until last week (approx Dec 16). Had a call that seemed I became muted to the other person (I could hear them but they couldn't hear me). Then the call failed/dropped. It seems to be ok for about 30-60 secs then it happens. I have been at home, not in a car so NO switching towers. Half the time I've been connected to wifi and half the time I am on the Verizon network (live on a farm). About the fourth time it happened I put the phone on speaker and I disconnected bluetooth (thought maybe it was trying to connect to another device?!). That seemed to fix it for one call, didn't work the next time. On another call I tried turning off both bluetooth and wifi and it seemed to fix the problem. This is obviously not a way to continue operating but it will hopefully assist someone not drop an important call!

I updated to 14.3 today (post all the above issues) and the issue happened within an hour talking to my husband so it did not fix the issue.

I have now turned off 5G and reset my network so shall see if that helps.

I have the issue with iPhone 12 Pro on T-mobile. Audio goes intermittent and can disappear completely for 10s or more. Affects both uplink and downlink. Seems to mostly be on 5G when on the move (annoyingly during teleconferences), even though signal strength looks good. Connections can be dropped but not certain yet if it’s a tower handover issue. I am going to turn off 5G for a while and see if that helps. I swear I have issues even on FaceTime Audio with a Wifi connection and had some issues yesterday with similar bad audio whilst Bluetooth streaming on a Wifi network, which made me think it could be an audio codec issue. Anyone else had audio issues on Wifi networks?

I’m not entirely sure this is on Verizon for several reasons. For one there are users on various networks experiencing the same issues. Also, I had no issues with my Galaxy Note 20 Ultra 5G for two months on their 5G network. I switched back to iPhone and my 12 Pro was flawless for quite a while. There was an iOS update one day and the next day I started dropping calls constantly. The most recent iOS update has seen my dropped call drops disappear completely.

Its difficult for me to blame my carrier when the timing of an issue or solution is exactly the same as an iOS update. Add in the fact that even when 5G is forced off and LTE, which has always been stable while being well established, doesn’t solve the issue. My dad has an LTE Android phone and hasn’t experienced these drops in the same areas I do. The only difference is I have an iPhone 12 Pro and he has a cheap Motorola phone.

Here is a text I received from Verizon today asking me to turn off and on my phone to see if the issue is resolved. I get what your saying and I thought the same thing it was Apple but after talking to both sides at the same time Verizon admitted it’s on their side.

Been using iPhone since it’s inception. Upgrade every year. This iPhone 12pro has been the biggest disappointment to date. Picked up my new 12 pro on release day. Constantly dropping calls and losing service with the iPhone not activated banner popping up. Happens every time my phone leaves a particular service area and in between changing towers. Airplane on/off rarely fixed the issue. Usually have to do a hard reboot to get the signal back, & then will only show 3G connectivity. Been to Verizon about the issue, they performed the network reset trick to no avail. Really disappointed in the product I’ve touted and promoted for years. Big Fail on this one apple. Hopefully you are working on a quick resolution.

Yes, it’s a known issue with the new iPhones worldwide. All we can do is wait on apple for a fix! My wife & I gave our last years 11pro’s to our kids, they have 0 issues. My sister got the 12pro max this past week, she’s having the same issues.

I am with Verizon and their support too has been horrible! They kept me on the line for literally over 3 hours and still no resolution. Wasted almost an entire day on it with them. They said something like the 12 is jumping on and off the 5G network causing this issue implying an iOS update will resolve it. We shall see.

Same here. After the update no data call drops on cellular. No issues with regular voice calls.

i also recommend to reset the service providers settings or even replace the sim card.

i will keep monitoring and post shortly.

Of course the call drops. The phone is doing a poor job of switching networks and towers. This is why the issue doesn’t exist on Android 5G phones. The networks fine.

I don’t drop calls at home whether I’m on WiFi, 5G or LTE. I’m in a strong signal area and I am staying in one place. Before the latest iOS update I’d drop at the same spot every time while driving. It was replicated 100% of the time. But again, only iPhone was having this issue. Since the latest iOS update I’ve had no dropped calls.

I am expecting to have issues again any day now to be honest. But I do believe the issue is on Apple as if it was a 5G issue this would happen on Android devices too. But it doesn’t. Verizon likely has tickets open because it’s a widespread issue. Not necessarily because it’s on their end.

I have a overpriced paper weight. I turned off 5g and have the phone set to LTE only which defeats my purpose of getting the phone. There are are pages and pages of complaints on this discussion and no word from Apple. I called them and I have apple care and restore blah blah, reset the network settings blah blah.... None of that fixed the issue. I exchanged my phone as well and still same issue with dropped calls. Now I am past my return date. Really wish Apple or whoever would own and fix this issue. Very frustrating.

Same issue. Network reset did nothing. Have to do hard reboot is a temp fix. Hoping for a update to fix this.

I’m having the exact same issues I’m with Verizon can have 3-4 bars LTE or 5G and all the sudden it just drops in the same area I just had full bars at and I have to go into airplane mode to bring signal back. Apple needs to fix there equipment.
