Apn/lte help

[FASTEDDIE427]

I just switched from AT&T to metroPCS and i unlocked my htc first. I found a few versions of what the apn settings need to be, however I cannot get LTE. Am I screwed because its not a MetroPCS phone?

Is it an LTE phone? Does it use the same LTE bands that MetroPCS uses? Do you have ALL the APN settings correct (including no spaces between the names in MMSC)?
