guys,

can i check with you how do i know it is connected to 3g network? i check on the top left is always shown "H",

lcy851031 & alucard1983, thanks for the details. BTW on the network setting, do we need to set the highest speed to LTE? or remain as 3G?

Thanks again for the information

need to find out also, tried a casing bought from lowyat member but not sure if it is the phone or casing problem, the volume button became malfunction after clip on the casing, my phone now with nokia care...

Want to let go my lumia925, less than a month old, come with screen protector and casing. Use as second phone, now changing to note3, still prefer android.
pm me for details.
