T-Mobile LTE? Cannot get LTE, only 4G topic

I cannot get LTE at all on my vs980, using CloudyStock 2.6 and cannot get T - Mobile to receive LTE. On 24A band.

Fiddled with all the GSM settings and the fastest speed im getting is 4/0.3 contrary to a similar phone getting 50/28 so its not reception

Anyone have this problem? THanks in advance
