Default Issues with 4g

Okay all, I've got a T-Mobile M8 S-Off and Sim Unlocked using it on Straight Talk AT&T Sim. If I switch to LTE only I keep amazing 4G service but if I don't over half the time in the same area I'm on H. Any idea why this is? Is there a setting I'm missing somewhere that switches to H if the LTE goes below a certain strength? With my Nexus 5 I never lose it so I am wondering also since I can set it as 4g only and keep service (but can't call out on LTE only setting) All help is appreciated.

Just to make sure we're on the same page here, are you using the *#*#4636#*#* menu? If so, which settings have you tried?

On my Sprint M7, we had a similar issue where it would work great with "LTE only" selected from the menu, but that would mean no calls or texts. "LTE, CDMA" would hold LTE longer than the default setting (CDMA + LTE/EvDo auto) and allow for calls/texts, but if we lost LTE, we'd be stuck with 1X data.

If you haven't yet, try the "LTE, WCDMA" setting.
