I have a sprint 64gb iPhone 5 and I have noticed that as my LTE is switched on in a non LTE area that it messes up my 3G. My 3G from time to time will drop to "o" in the middle of sending a text msg and then the text will fail to send as well as just dropping to "o" randomly through normal usage. Is this normal behavior for having the LTE switched to on in a non LTE market? It is quite annoying as my iPhone 5 came with the LTE switched to on by default and I am not able to send texts from time to time. Some help and insight would be great as I am wondering if I should take my phone to a sprint store and swap it out for a new one.
