Hey there!
From what we've been told by HQ is; some areas are cap'd until a complete build of the LTE network is widely spread. I live in nor-cal, LTE speeds here are from 3-5mbps Whereas (from what I've been told) Detroit and Florida are up to 10mbps + metropcs was supposed to uncap (in nor-cal) to 14-16mbps around January/February. Sooo..from what I'm told, yes metrics is capped till further LTE expansion. It had a lot to do with his some towers are a split of LTE. equip and some old equipment, once all tower locations are fully converted to LTE ..it might stay cap'd till then. Ill keep the forum updated
