IPhone XR , LTE and WiFi ISSUES !!!! DROP CALING

What kind of WiFi issues are you having? I have an iPhone XS (not the MAX; regular size), and I just discovered that the Wifi connection to the phone is extremely slow/limited. I have an iPhone 6 and a 2015 MacBook Pro that are both getting excellent Wifi speed to each device via my high performance router, while my XS is crawling.

When a customer pays a large amount of money for a product that's expected to work as described, they have every right to log questions, rants and anything in the middle. I am on T-Mobile and I have extremely slow WiFi issues on my iPhone XS. Are you going to tell me that it's also T-Mobile's fault that my Wifi on my phone isn't working? A Wifi network is not a cellular network. One has nothing to do with the other. I turn my cellular OFF and keep WiFi on, and STILL get a slow WiFi connection on my device while on my gigabit home connection. I have an Asus AC3100 Dual Band Gigabit WiFi Gaming Router, connected to Verizon Fios on a gigabit plan. So it isn't my router, or T-Mobile's cellular network. I have other devices on my home router getting super fast speeds, and I've replicated the problem on other WiFi networks outside of my home with the same results. Please don't let your Apple loyalty discredit valid concerns from other Apple product owners.  

I wasn't talking to you. Your issue has absolutely nothing to do with the OP's problem. Go start your own thread instead of trying to hijack someone else's.

And no, it is not OK to rant here. Try reading the Apple Support Communities Terms of Use.

We had the same problem... mainly with going from WIFI to LTE. Basically the reconnect to LTE did not happen, and we had to reboot the phone. A knowledgeable person at the Apple store gave 2 solutions:

• Replace the SIM card. This worked!
  • Not sure why it worked... we replaced the XR once and still had the same problem. But the new SIM did the trick.

AND/OR

• Reset the phone to the factory settings, as if brand new, then restore from recent back-up.
  • We did not take this step, since the SIM worked.
  • The Apple guy said that the iPhone 6 backup could be corrupt or just had a problem when 'setup from the backup'.

Hope this helps.

Meant to respond sooner... we seem to have found a fix:

Came across a guy at the Apple store who gave some options. Here goes:

• Replace the SIM card.  This worked!
  • Not sure why it worked... we replaced the XR once and still had the same problem.  But the new SIM did the trick.

AND/OR

• Reset the phone to the factory settings, as if brand new, then restore from recent back-up.

I just got off a chat with Apple Support. They ran a diagnostic on my phone and all the software looked good but the analytics tool that they use (found on your phone: settings>Privacy>Analytics) could not get a read on the hardware. I have to go into the Apple Store and have them take a look. I'm pretty sure after they look at it, I'll be leaving with a replacement phone. Nothing else has worked; not even a factory reset. I have the same issue as you. I'm sure your phone is still covered under manufacturers warranty and may be eligible for replacement as defective. Only way to find out for sure is to bring it to an Apple Store, if that's an option for you, depending where you live. You may also be able to send it in. If they find it's defective, they'll send you a replacement.

OK... so what's your point? Do you actually have a question, or are you just here to rant?

I've had iPhones since day one. We have multiple Xr's now on AT&T and have absolutely NO problems with LTE or WiFi calling. None. Nada. Zip. Zilch.

We also have problems with the XR as well. Apple replaced phone, but same problem occurred. WiFi to LTE doesn’t work. Playing with the WiFi Assist (turned off and back on again) and Cellular Roaming Settings (set to Voice and Data) is working now. Will test more today... as others reported temporary success.

This is not very smooth from the Apple perspective (compared to prior phone releases).

I am in the same situation as others. Using Apple iPhone for years, upgraded to iPhone XR from iPhone 6s Plus in January 2019. A disaster to be honest.

From start there are problems with weak 4g and WiFi. Going in circles with apple and network provider. Apple has replaced the phone with new phone but the issues are still there, nothing got fixed. Network provider has done all the checks, according to them nothing wrong with the reception/signal.

I wish I could have researched it before buying it. I hope Apple can acknowledge the issue and fix it.

Verizon and Sprint have both been having problems with Voice over LTE and WiFi calling.

Turn off WiFi calling and set LTE to data only.

This is a carrier problem, not a problem with your phone.

When you pay $1000 for a phone it should work. Period.
