Hey Multo,
(Am I correct in assuming you're from the Philippines?)
Which network are you with? I am currently using a Smart Prepaid LTE SIM. With the 925, I usually average just around 5Mbps DL even when I'm right smack in the middle of an LTE coverage area - like the UP Diliman LTE areas for instance. Just to test it out I even went to several areas listed under Smart's LTE coverage list (Ortigas, Araneta Center, UP, etc) and still no observed improvement.
I've just switched that SIM over to my 1020, but it's just my second day using it so I haven't really observed if I'd get better connectivity with it. Any advice?
