not sure about the other YES 4g modem, but the Huddle hv a flaw. like I place the huddle behind 2 walls the signal turn from green to red, mean the signal cannot pass 2 wall (inside house) not shopping mall.

btw, I mean the signal in. Not the wifi signal to PC/HP/tablet.

well these is no such thing like 512Kbps. unlimited data means boleh use at 128Kbps once quota breached.

i am using YES Zoom we assume it's best near windows. i practically tried but signal keeps blinking cannot get line. you need to position all possible avenue for best spots. for my case at wangsa maju. i cannot get a decent signal. lastly i only get 1 bar with 2Mbps speed but sometimes disconnect...   

i had log case to YES support and perform all required action. the network support team called me. my issue is beyond help. although the area is under coverage. they told me sales team will never tell you. this is one common problem by apartments & hise rise. YES they do not warranty this on their coverage map. so for new users wanna sign up. please read this very extremely carefully.
