I have the S5 and having major problems with this exact issue now. Is there any kind of work around or fix. There are a bunch of us on the Sprint Forums trying to get a response about why we lost all LTE once we switched from our S3 to the S5. Any kind of work around or fixes or do I return the phone and get something else?

Here is my post on manually turning on LTE for the S5 (keeping 3g, voice, and all as well) here: http://s4gru.com/index.php?/topic/1961-network-visionlte-cincinnati-market/?p=307815
Hope that helps!
