iPhone 12 Pro Max dropping calls and poor phone signal

I updated the software to 14.3 and AT&T troubleshooting restart seem to help with the data calls on cellular in downtown DC the call did not drop on WhatsApp for almost an hour.

i did not restore the device just updated to the most recent version and did the restart with AT&T troubleshooting on AT&T app.

I have Verizon, I previously had the 11 Pro Max. I upgrade my iPhone every release. I have never had service issues in the 8 years iv been with Verizon. Ever since I got the 12 pro Max, iv had the worst service! People can’t hear me, my calls drop, I can’t dial out.

I’ve drove all over the place today and had phone calls active for nearly 2 hours without an issue today. I had the same result yesterday too. Not a single dropped call since the new iOS update which has been nice. But I’m not convinced it’s truly fixed which is evident by this thread. Just waiting for another drop to be honest.

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.

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.

Yes same exact thing that happened to me constantly! I am telling you guys restore your phones by hooking up to your computer and then restore from a backup and that I bet will help. DO IT or stop complaining it did help.

I tried that, restoring from backup using my computer. I still have the same issues. What works for one seems may not work for another but in the end the issues seem to return. I have reset network settings and have run diagnostics with both Apple and Verizon. Nothing has resolved the issue. At this time I have 5G turned off. This issue is all over not just on this forum. I just wish the carriers or Apple would acknowledge this issue and say something. When will this be fixed? Sorry... glad that worked for you.

That sucks. Believe me I still have issues with my phone just not nearly as bad with the restore and the latest iOS update. If I could return this thing I would but I can't so I have to make the most of it unfortunately.

Right..... that is what I was saying to the person that said do the restore. It does not work. Nothing I have tried has worked. Verizon DOA my first phone and I got one they just got in. Same issues. I want someone to acknowledge there is an issue. Apple needs to say something we are all having issues with this very expensive paper weight.

go into settings and change your cellular data settings and change it to 3G. I did this and it works. That being said, I cannot use the LTE network. Every issue that everyone has been talking about, I too was dealing with the same problems. This works but apple will need to come out with a fix. Hope it works for you.

Yikes, 3G in 2020 (almost 2021)?

I think I’ll pass on that one.

Its unbelievable that we’d even need to consider that as an option in areas with strong LTE/5G signal. But here we are with $1000+ smartphones they can’t even process tower switches properly.

My wife and I both upgraded to I phone 12 end of October 2019. Since then we both have callers constantly complain they are only hearing part of our conversation. Also get many dropped calls. These phones need to be replaced by Apple as they are bit fit for use. We are in T mobile. I will be talking to T mobile.

I highly recommend updating your carrier settings with your service provider, not necessarily on your device. at&t has the option on its mobile app trouble shooting section, the app tells you that it sent you a signal and resets the cellular settings after a device restart.

once I trouble-shot on at&t and updated the software, the issue was resolved.

iPhone12, 2 months...should have returned it when I had the chance.

I am having the same issue/s. I have spent hours with support; ATT and Dell...when I could not connect at all.

One thing that "helped" was to update the driver on my Dell. At least I connected, but that is it. VPN just flat out does not connect, constantly disconnects (unable to work from home...big problem). Connectivity to Zoom last about 30 minutes IF all other devices in the household are off, including my husbands SE...which works fine btw.

Phone/Text/Email reception is spotty at best...where it use to be solid.

Wish I had my 6S back, I never had connectivity issues with the hotspot, VPN or Bluetooth. You would think Apple programmers could figure this out...how did they go backwards?

I was told that I need to keep up with the latest version...I check that daily in the hopes of a magic update that will give back the quality connections I was accustomed to. I am going to continue to try for a bit due to the investment already made ($1200) if not better soon I will be switching to another phone...not Apple...as this is impacting my work capabilities.

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?
