Iphone X weak signals

So the issue is that the A1909 model has a modem in the ATT version of the phone that causes a significant signal drop on LTE. ATT only has this model. Verizon has the A1865 Model which is much better.

Apple will continue to Ignore this issue and give you the run around because there is no fix short of returning the phones and starting over. I have spoken with 3 Apple senior managers who have each sent me a new A1909 model, all with the same issues. They all took me through the 10 steps on their site including connecting me with ATT to check outages and low signal (in Chicago - Right!).

If you are stuck with an ATT phone the only way to boost signal is to go into settings and cellular and turn off LTE. You will notice signal strength immediately comes right back up to 4Bars. You will still have 4G just not LTE so will be a bit slower. If you can transfer to Verizon you will get the A1865 Model keep your number and the problem goes away.

Good Luck

Just for everyones information, Apple replaced my phone with same model (A1865) and it’s all good now. It was definitely a faulty unit. Apple store UK refused, but different apple service provider agreed with my complaints. (Because unfortunately the standard Apple diagnosis software can't pick this issue.)

Had the iPhone X for a few days, noticed a problem yesterday.

My wife and I were sitting across from each other in a coffee shop. On her iPhone 6 she had three bars of cell signal, on my iPhone X I had one bar. Over about twenty minutes I tried numerous times to connect to different web sites, phone indicated that it could not connect. During that time I shut down and restarted the X, no change. Meanwhile my wife was happily surfing the whole time. An hour later at our home location we both had three-bar signals.

My previous phone was an iPhone 6s Plus and on the small handful of occasions that we compared signals they were the same.

I've just read disconcerting information about Apple using different cellular modems in different models of the iPhone X. Model A1865 contains a Qualcomm modem which online commentators seem to agree is a superior modem both in performance and in its global adaptability to all types of systems. My Canadian model A1901 phone contains the Intel modem which commentators say is a weaker performer and which will not work on some cell systems (CDMA types) in other parts of the world.

To determine the model of a phone, tap Settings / About and tap the Model number; it will briefly reveal A1865 or A1901 (or A1902 for Japanese phones).

I called Apple again and went through the same checks over and over ref to my weak signal while talking. This tech finally asked me to go into settings and take my phone off LTE for talk and data and which it to just data. The phone dropped out of LTE and went to 4G and my phone calls cleared up. Apparently iPhone X has a problem with LTE, so now I get to use my new phone but not at the speed it was designed to handle.

I had the same problem plus dropped calls. returned phone. Was advised after return that SIM card supplied by Apple should have been used as it contains latest technology. I had used the SIM card that was in my my iphone 6. Have not received new phone yet but hope it works-- really like the phone

Sent from my iPhone

I did open an Apple Support session, had me reset the network connections, reboot the phone. Absolutely no improvement, reception is dismal in places where I never had issues with the 7+. It won’t even pick up my Home WiFi unless I am close to the Airport never used to have that issue. Next step Support wants me to erase and restore my phone. With all the similar complaints this is a waste of my time and a pipe dream solution doomed to fail. It’s clear these phones have a major antenna reception issue. I will most likely send it back and get the 8 until they sort this out. They can add this problem to their current fiasco of slowing down older phones to save battery life. It’s too bad, was a nice phone with great features but they seem to have overlooked a critical feature,Signal Reception!!

Logre que me cambiaran el equipo en USA, pero me dieron la version A1865, llevo con el 1 semana y el problema no se me ha vuelto a presentar, al parecer el problema se debe al modem Intel que monta la version A1901.

I CURRENTLY OWNED AND IPHONE X SOFTWARE VERSION 11.2.6 IF U ACCESS THE SETTINGS MENU AND GO TO CELLULAR THEN GO TO CELLULAR DATA OPTIONS AND WHERE IT SAYS ENABLE LTE IF U DISABLE LTE YOUR SIGNAL STRENGH WILL IMPROVE BUT U WILL NOT BE USING LTE DATA IT WILL BE 4G THATS AT LEAST WITH MY CARRIER SERVICE WHICH IS ATT. SO THATS IT THANKS AND HOPE THAT HELPS.

Since I have had the same problem with two different carriers since I have had the same problem with two different carriers (ATT and Verizon), I am pretty sure the problem is not related to the carrier. However, Verizon engineers are supposedly looking into it. I also again contacted Apple tech support, they sent me yet another iPhone X, same problem. I then went to Apple and bought a new iPhones 6S plus, and it works! I have been carrying both phones with me for the last few days, and have noticed a number of occasions where the 6S plus shows bars when the X does not, and not surprisingly I am able to make calls on the 6S plus, but not on the X. I even restored the X from an iTunes backup of the 6s+. Both are running iOS 11.3. Same problem. Bottom line is that I have done extensive troubleshooting, using my (uncompensated) time and my money to buy the various phones, and to wait on hold and at the Apple Store, and to go through the various numerous troubleshooting steps with both AT&T and Verizon. It appears that I have successfully ruled out the issue as emanating from the operating system, or from the network. That only leaves the iPhone X as the source of the problem. As one more piece to the puzzle, I intend to go tonight and buy an iPhone 8 plus, and see if that one is better than the 10 or the same. However, no matter what, I paid for an iPhone X, and have nothing but difficulties with it in terms of signal. In all other respects it is a great phone.

Apple owes us a solution to this problem immediately.

I live in Thailand.

I’ve already updated carrier service but the network problem after going to the low signal area has been still persisted. After i disable 4G, moble signal of iphone X work well.

I’m thinking of making the switch to the A1865 model sold through the Apple USA store instead of my A1901 device. Too many connectivity issues with the A1901. The Intel modem is very poor compared to all of my other devices that all use Qualcomm, including previous and current iPhones (6s Plus, 7 Plus, and even 8 Plus). Challenge is how to get my hands on one, being in Canada. Apple USA won’t ship cross border and all models available here are A1901. The comment made by one of the posters above how he was sitting in a cafe unable to connect to anything is precisely the kind of ridiculous behaviour that I’m seeing. Devices were already swapped to no specific effect.

I have also provided Apple with a slate of logs from my device that they started to analyze but I am pretty tired of being their unpaid beta tester of a $1,500+ CAD device.

Jonathan,

I have two iPhone Xs, an A1905 model and an A1865 model. Both are equally unreliable at cell service. I expect that both are equally unreliable at data (using the web) although I've had most of that trouble using the A1905 because...

I have an iPhone 8 that is used pretty much exclusively as a hotspot for other devices. It has been fairly reliable in this role, though it is NEVER used while I'm moving around, only when I'm settled somewhere. Because both iPhone Xs are so very unreliable I tend to do much more data / web stuff using an iPad through the iPhone 8 hotspot. I can NOT tell you that the iPhone 8 is a good reliable data phone, just that it's working OK in the limited role I have for it, and I hardly ever use it as a cell phone.

My iPhone 6s Plus was still fully-operational when these phones came out. I had it posted online to sell it after the first iPhone X (A1905) arrived, but within days took it down and have kept it. I now frequently have it with me along with an iPhone X because it continues to be a much more-reliable cell phone. I can drop or fail to make a call with the X, pick up the 6s Plus and immediately make the call successfully, sometimes in exactly the same location, sometimes just a short distance down the road.

My wife's iPhone 6 is still fully-operational. I've been in a few situations in which one or the other of my iPhone Xs will not connect to data or make a call, and her phone works perfectly. If you think she'd restrain herself from taunting me about spending so much money on two iPhone Xs that flat out don't work properly on cell networks (I've used mine on two different networks, in places all over North America) you'd be wrong.

All of our phones are carefully kept up to date with latest software. Don't let anyone tell you that these issues are related to iOS, or to your SIM card, or to your phone needing a reset, or to failings by the cell phone company. They are not. These "solutions" have been tried by many here, and they make no difference at all. There is an issue with the iPhone X hardware, and many of us are hoping that Apple steps up to it soon.

You have probably already tested this, but if not:

1. Test to disable WiFi assistant

2. Disable data under cellular

Is it the same?

I also recommend that if you have like > 2 years old SIM card, ask your carrier to give you a new one. Some technicians have told me that older SIM cards are not the same as the new ones.

Saw this just now: Update your carrier settings on your iPhone or iPad - Apple Support

Re: alanfromokehampton's assertion that "I assure you it is your carrier", I have now traveled with my *second* iPhone X (the first was replaced, no improvement) to various parts of Canada and have recently spend eleven days driving from Canada to Florida. I've therefore used at least two carriers and used them in widely-dispersed parts of their networks.

I've had more trouble with cell reception/transmission, dropped calls, and making calls in less than two months with this phone than I have had IN TOTAL since I bought (upon their release) the iPhone 4, 6, and 6s Plus.

The problem is the phone, NOT the carriers.

Absolutely it is the phone and/or phone firmware (more specifically, I suspect it is the modem and modem firmware, or perhaps even overly aggressive battery saving at the expense of the cell radio). I have now gone through four different iPhone X devices that all exhibit very poor reception, all identical to each other, and all worse than any other phone. I still have an open case with Apple about this but I’m not holding my breath on a fix. I have gotten only silence lately.
