    Thanks for this post. I had read another article and it just said disable LTE. I thought fine i’ll hold down the radio button and it will turn it off. No such luck! I could change settings but I didn’t really know what they were for. You explained it:it would be disabled by going to a3g setting. Thanks much./Bill
