I currently use ATnT.
I know everyone is suffering about getting LTE on keyone.

But in my case, the LTE is totally okay in my room, and I have 2 signal bars.

When tested with youtube video, it plays clips very well with LTE.

However, making a call is not available.

In my common sense, if LTE were okay, the calling should be alright, since LTE requires more communicating or downloading mobile data than the calling.

Would you have any idea about this problem??

To add more information of my room, previous iPhone was totally okay when it comes to making a call.

Thank you in advance for you guy's response.

Assuming you're going down to 4G when on a phone call. I've NEVER stayed on LTE when making phone calls. Could be the area I'm in I don't know but I've been with ATT for years and never seen this happen when phones finally got LTE.

That's the problem that I have. That's why I'm returning the phone

I doubt very seriously if you get a replacement it will change.
