Better signal??? Yes ...

In some areas Air is LTE coverage and there is 4G coverage. For example road a had LTE coverage and road we had 4G coverage and you were traveling on the road be using LTE your signal will not be Astro because there is only 4G on this road. The way to fix this is if you have an iPhone with iOS 7 .4 install go to settings – cellular – and turn off LTE this will switch your iPhone to the 4G network which is stronger than the LTE network on this specific Road. You can use these tips anywhere in any location if 4G is stronger than LTE simply turn off LTE off to use the 4G network. This only seems to work with data I have never seen two big of a difference with voice communication.
That's it for now comments below and be sure to correct me if I'm wrong.
