Iphone X weak signals

I received my iphoneX yesterday and set it up with my previous cellular network. Since then i have noticed that signals strength is significantly weaker than before both at home and on the go. Call kept disconnecting while travelling. Never had any sumch problem on iphone 7 ios 11.1 and 11.2beta. I have tried ringing apple care and they have asked me to reset network settings which i have done but issue is still there. My old iphone 7 at same network and same ios is in my other hand showing full signal strength. Is it an issue with iphoneX signal antenna?

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

Gosh, your story is sobering. Two Xs and a 6s, oof. I'm still going ahead with my plan to get a new X with the Qualcomm modem and probably change to Verizon as ATT had been demonstrably uninterested in improving cell reception in our California semi-rural area. I'm just hoping that with the better (?) modem and Apple waking up to their responsibility to make more reliable products and work on the software. Considering, though, selling this thing and getting a solid 7s. Ugh.

I ‘upgraded’ from a 6s (worked like a charm) to this X. Now I’m strongly considering to sell it and get ....? Is the 8 solid? 7? Which has a solid modem that works well with iOS at present? I’m at a loss what to do. Maybe just wait Apple out for a software fix. One of you guys said the Qualcomm modem is no better than the Intel. This has got to be a wider problem. Is it only being recognized by users with overall spotter cell service or ....?

Same problem. Poor signal during phone calls since upgrading from the 7plus to the iPhone X


Sick of people not hearing me (never had that before upgrading )


I’ve been with Apple 8 years and it looks like I will be returning the iPhone X for a refund.


Think there is some problems with this “new” phone. It’s got some problems. Think it has been rushed threw. And Apple will keep it quiet. But I’m going to video me taking the phone back to the Apple store


I’m returning mine within 14 days unfortunately and going back to the 7 Plus. Gutted and relived

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’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.

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.
