I just got a warranty replacement phone for my iphone 7 plus rose gold because my signal would alternate from 3G to 1x and I just received my
replacement phone and it is doing the same thing, I can not get on the internet at all or on my apps without being on Wifi. My husband and son
both have a iphone 7 plus in black and their signal is always showing LTE, so I know there is nothing wrong with our coverage area. How can I fix my phone I went through all the troubleshooting steps
