    The update isn't the issue. My phone was so bad (This is with IOS 12.1.4 too) with no LTE and WiFi, I had to reload the software from iTune. The WiFi would turn itself off…..ON IT'S OWN!!!!! After the reload, I got 3g and no WiFi connection. After multiple calls to Apple customer service, it's sort of fixed………I think. The WiFi still turns itself off!!! I just noticed that the Cellular Data was off as I wondered why is took 6 hours to get an voicemail message. It's not the carrier either……been there, done that, wrote the book!!! I wish I had seen the connectivity issues prior to buying this in December as I would have bought an 8 Plus instead!! Some carriers are replacing the XR with the X and 8 Plus. I bought mine from Apple and they haven't ever offered to replace mine!! On the Apple XR community site, there is just an overload of complaints about the LTE and WiFi connectivity issue and it doesn't look like it will be resolved anytime soon!!!! #SMH

    I’m having this problem with the 4G LTE on Claro Mobile Network (Cingular) (Puerto Rico U.S.A) it stays on 3G no matter what. I’ve been trying all but nothing seems to work. it’s been like this since the 12.1.2 update and now I’ve upgraded to 12.1.4 and it keeps doing the same.

    February 20 2019 and I’m still having this issue on the iPhone XR. I had 12.1.2 and now I have 12.1.3 still the same. Come on apple!!!!! This is so annoying!!! Yeah the workaround only works for a hour or so. I have to toggle airplane mode on then back off at least two to three times a day.

    Thank you!!! I have been unable to text for days!!! Apple was no help at all. They wanted me to factory reset my phone and I said no way! Shutting off LTE fixed the problem. ?

    Can you please check and confirm if the way you switch on your Iphone XS Max or XS changed with the ios version 12.1.1 and 12.1.2 as i noticed when i first got my XS Max i only need to tap to switch it on but since i updated to version 12.1.1 things completely changed, now i have to tap and hold for some seconds like the older devices to switch it on. it seems like non of the tech youtubers talk about that or even noticed that issue. i follow up your vidoes always and they are very helpful

    Hi Aaron! I tried doing this But it doesn't work. My phone doesn't have cellular settings. My problem is with the Data. Apps like UBER doesnt work. App store works but when you download an app, it doesnt download. Imessages dont work. I tried turning wifi calling OFF and restarting the phone. It didnt work. 🙁

    Another thing i tried was to reset the network settings. This did work for sometimes but again i'm still facing the same issues.
