4G LTE not working (only 3g/HSPDA/H+)

:confused::confused::confused::confused::confused: :confused::confused::confused::confused::confused: :confused::confused:
I am using Verizon LG G3 VS985
My Network is Telenor, Zong and Warid which is 4G LTE
But I can't use 4G LTE service in it,
I can only see H/H+ data signals on my phone...

My phone is Rooted...
My Wi-fi tethering and sharing is now working...
But

Problem is, How I can use full 4G LTE on my phone
