I have a 6S and my wife has an SE. We both are on Verizon and both are running the latest iOS update. Both of our phones are set to Voice & Data Roaming, as well as having Voice & Data selected for LTE. We are traveling in Puerto Rico where I will often lose signal completely, and when I do have it, it's only Extended 3G. My wife will be sitting right next to me with her SE and have Extended LTE even when I have no signal. Any ideas why this would happen? I thought maybe the SE has some additional LTE bands that the 6S doesn't, but that's not the case.
