Just recently got the iPhone X to replace my iPhone 6s and the X is getting 10x worse reception. I use to able to use my 6s at work with zero reception issues on data. My iphone X can't even send a text message. I've tried turning it off and on, airplane mode for a couple minutes, turning the cellular data off for a few minutes, nothing seems to help at all. Very frustrating that my two year old 6s has zero issues at work and my X which is brand new and well over $1,000 can't even maintain a 3G signal. Trying everything to figure out why this is but no fixes yet.
