K ... Here's what I THINK I know... Lol
With data off completely.... Calls and texts still work. A great way to save battery destruction in poor reception areas as well.
If LTE is on, and you make a call... Phone automatically switches to GSM, or 4 or 3g. I think that's what I've read.
If the above is true, then you're saying forcing LTE won't allow it to drop out of LTE to make calls. That makes sense.... I think. The trouble I'm having is understanding this..... If you can make calls and texts with data completely disabled.... I guess I'm not getting how being on LTE only can affect calls. Or is kind of like LTE is taking over the radio completely.... So calls and texts don't work. So on auto, LTE shuts itself down to allow you make calls. And of course with data disabled LTE is obviously off, so yes you can make calls and texts.
But with LTE forced on.... It basically hijacks the radio, not allowing voice and I assume Sms.
Have I finally got it? Lol I needs to learn. 😉
