SAMSUNG S4 4G NOT ACCEPTED

I have a Samsung Galaxy S4 and upgrade the version 4.2.2 to new version 5.0.1 I have also installed a 4G SIM card.

When I tried to activate 4G/LTE I find that the phone does not provide me 4G/LTE capability.

Here's what I have;
Model: Gt-I9500
Android Version: 5.0.1
Baseband version: I9500DXUHOA1
Kernel Version: 3.4.5-6164126dpi@SWHD4320#1Thu Nov 26 22:18:51 KST 2015

Build Number: LRX22C.I9500XXUHOK5

Secure boot status Type: Samsung

Network Mode only shows;

WCDMA/GSM
WCDMA only
GSM only

Have I got a dud phone ? or can I do something to get 4G/LTE?

Any advice will be appreciated
thank you.
