Network Mode always GSM only on Samsung Galaxy S5

[Danzy83]

The network mode on my Samsung galaxy S5 device is always set at GSM only. When I try to change it to WCDMA only or GSM/WCDMA (auto mode) it changes back to GSM only. The area I am has 3G network and most devices I see have H but mine always shows as E no matter what I do. When browsing it takes a long time for pages to open because its always at E.

I have factory reset the device but still facing the same problem.

Is there any way I can solve this problem? Thanks in advance.
