Poor signal with iPhone 12 Pro Max

These allegations are completely untrue.

Millions of users have no such issues, and if the phone couldn’t handle switching towers you wouldn’t be able to hold a call for more than two miles or so.

The only way to address this issue is for your cellular carrier to fix their network.

I tried Bell Telus and my son’s SIM card with Roger in my phone. All same issues on the iPhone Pro Max. When I’m in my car speaking to customer I drop the call so it tells me poor antenna in my phone. Consider yourself luck to have a phone that works. You can’t tell me it is true when I have tried all three major networks in my area. Why do I have no problem with reception with my old Samsung android phone. Tells me I have one of the duds or defective phone.

Bell and Telus shares network towers. Reason why I tried my son’s SIM card in my phone and had same problem he is in Rogers. My friend lives in Quebec many provinces away different network same phone same issues as I have. She finally gave up and purchased a completely different phone. I can only wifi call at home but it is useless on the road. I’m trying to work with Apple to replace. So please don’t say COMPLETELY UNTRUE. I wish I was one of the fortunate ones that receive a good one. There are lots of lemons for all products.

It doesn't necessarily matter if they share towers, the question is do they use the same Base Station Controllers and other hardware.

If Wi-Fi calling doesn't work for you, that's 100% an issue with your cellular carrier. Apple has absolutely nothing to do with Wi-Fi calling, that all occurs over your carrier's data network.

Went to the boat races yesterday. Cell service was very limited in the area but everyone could send and receive texts—except me! No service and I was the only one with an iPhone 12. Sucks! Looks like my new SIM card isn’t fixing the problem.

Since SIM cards only provide you access to a network, it’s no surprise they did nothing.

Did those other people with no issues have the same carrier you do?

I know there are areas near me where AT&T users have a full signal but Verizon users have no signal, and vice-versa.

i went to the apple store and they ran diagnostics on my 12 max. All was well. The tech turned o. Tower roaming and turned off 5G. 5G is not ready for prime time except in very large cities. Medium size cities are still far from fully operational. Sonce doing those two things the reception has been much better. However no where near as good as the 8 Plus that was my previous phone.

My husband and I have the same sim provider, with same plan. But his Android doesn’t have any issue with wifi connection or calls . But on my iPhone signal reception is bad. Please don’t tell it’s the problem with my sim. We tried switching the sims. And found out it’s the issue with this dumb phone

Most of the other folks have the same carrier as me. This phone is a dud and I hate it! I am not rich, so for now I am stuck with it. It may be issues with the carrier, BUT Apple should not have sold phones that are not compatible with a major carrier!

It’s would like selling a microwave oven that only heats food half the time. You would then expect a product recall or the manufacturer to make it right with replacement or money refunded. You would not expect them to blame it on your power source (after thousands on people complained of similar issues) or the type of food you were cooking. Most companies would make it right for the consumer.

Wi-Fi calling is an interface to your carrier done over the Internet using Wi-Fi and has nothing to do with their cellular network or towers. It’s like making a FaceTime audio call that gets routed over your carrier’s Internet servers instead of Apple’s.

So your conclusion that is is the phone rather than the carrier cannot in any way be proven or even asserted by your use of Wi-Fi Calling.

No, it’s like you bought a radio to pick up a station you saw a TV ad for that played your favorite songs, but the radio station isn’t actually broadcasting a signal and you blame the manufacturer of the radio.

If all my friends had cheaper radios that were getting that radio station, I would know that it was my radio—not the station and I would get rid of it and get a different radio. If the radio manufacturer would not take the radio back, I would feel ripped off.

Though that's not what's happening here.

A great example is in 1945, the FM Radio band in the US extended from 88 - 106 MHz. Within a few years that was extended to be 88 - 108 MHz.

If you had an early 1945 radio, you couldn't receive frequencies above 106 MHz.

So if the radio station was telling your friends with old radios to tune to 95.1 MHz but you to tune to 107.5 MHz to receive their new, better signal, but they hadn't yet turned on their transmitter at 107.5 MHz, you'd have the exact situation you see now.

Except you don't get to choose the frequency to tune to, the cell tower base station controller tells you, based upon which frequencies your device says it can receive.

Older phones don't get told to use frequencies only newer phones can receive, but if the provider hasn't yet optimized their towers for the new frequencies, you get exactly what you see: older phones told to use old frequencies work well; new phones told to use newer frequencies do not.

How would you expect this to work?

AT&T is ready to roll.

Verizon says they are ready to roll.

Apple introduces their product.

The vast majority of AT&T customers have no issues whatsoever.

Many Verizon customers have issues but Verizon blames Apple.

Apple did nothing wrong, but Verizon gets to shift blame and make their stockholders happy by not sending crews out to towers.

Further, not all Verizon customers have issues, which absolves them of direct blame.

Issues with carriers are between their customers and the carrier and Apple isn’t going to get in the middle of that relationship.

Meanwhile the only thing Apple can do is make sure there are no hardware or software issues and tell people to… contact their carrier.

I'm in New Orleans right now. My iPad Pro (not 5G) had 4 solid bars on LTE. My iPhone 12 pro max has 1 bar. These two devices are right next to each other. So, reading through these replies, I turned off 5G in cellular settings and restricted it to LTE, but that did nothing. still the same terrible reception on my new 12 pro max and solid reception on my iPad pro. I'm not seeing any other solutions coming from this group, even with Apple support. That tells me the 12 pro max has a bad receiver. big bummer.
