iPhone Xs Max LTE/Wifi disconnect issue

My iPhone Xs Max (256GB variant) is facing couple of connectivity issues:

All of a sudden (4-5 times a day) it loses internet connection via Wifi, it shows wifi signals on my phone but no internet. My other devices connected to the same network works fine during that time. My iPhone shows this internet blackout for like 2-3 mins and starts working back as normal after that.
Whenever my phone switch from Wifi to LTE (when I leave home or work) it takes 8-10 mins to connect to LTE network, the phone does shows LTE/4G network immediately but doesn't connect to internet. I had to wait for 8-10 mins for it to connect or toggle Airplane mode on/off to get it connect manually.

Apart from these above 2 issues I am also facing the other common problem that other reported where my iPhone doesn't charge when I connect charging cable and phone is in sleep mode.

Pls help. I tried contacting Apple Technical Support in Netherlands but seems like they are not aware of all this, they even denied that others are facing similar issues whereas I see apple related forums filled with the same.

iPhone XS Max, iOS 12, 256GB

I found the fix of this problem. It seems like a format & fresh new installation fixed it for me. It’s been more that 2 weeks now with no problem. Remember to do a full reset from your Mac or PC not from your phone as doing it via Mac or PC only do a fresh OS installation after format. Also I didn’t restored from previous backup but did a setup from start by manually installing apps.

It was a hassel but atleast I now know it was a software issue not hardware.

Hi I’m having the same issue getting disconnected automatically with the wifi while other gadgets are all perfectly connected. I have 12.1.4 ios. I called apple and will see what happens next and I will update this. I even recorded a video for that.

If it works then the only rationale I can think of is old SIM cards compatibility interferes new “Xs modems” operations. Since your iPad doesn’t have SIM card so no compatibility issues.

Same here. Here are two screen shots showing that my phone states that I am connected even though IT IS NOT!

I will try that. I am not very hopeful. If the issue persists, I will try to get a replacement.

Thank you for the suggestion. I will head to my AT&T store tomorrow to pick up a new SIM card. I know for a fact my SIM card is at least a couple of years old if not older. That could potentially be the issue if it ends up being resolved for you. I already have 12.0.1 and that didn’t do anything for me. I’ll give the new SIM a try. I’ll also report back any findings I may come across. The only reason I’m skeptical that the SIM may not help is because my iPad Pro 10.5 has no SIM card, and it stays connected to my home WiFi from the same room with no issues. I’ll try anything at this point though. Thank you again for responding.

Is this the AppleCare number you called: 0800 0201581

Contact Apple for support and service - Apple Support

I would suggest that you call the team one more time and advise that there is performance issue with wifi and cellular connectivity.

I found solution (at least in my case)

I had same problems with my iPhone Xs, my Cellular wont connect to network.

I tried everything, switching Airplane mode on and off, switching Cellular on and off, reinstalled the whole phone,

after i did reset of the network settings and rebooted it helps.. but just for a while, after a couple of minutes it lost signal again :(

Then i tried this and it seems to solved my problem as far:

I manually select the proper Network selection (Settings / Cellular / Network Selection)

- there is option for automatic selection or manual, so i switched to manual and choose my network

I reset settings for Cellular data network (Settings / Cellular / Cellular Data Network)

after that my phone is still connected to the carrier network, its been 12 hours since that and phone is still alive.
