The spees I got on 150 Infinite, due to previously I only can get this speed at Postpaid 110 plan, so the speed is fine for me. And if u asked why I don jz get 80 Infinite, Im using this plan as my main broadband at my home, so I nees to have unlimited tethering. Just order Huawei 4g usb wifi modem from Taobao and waiting for it, currently using 4G mifi to share hotspot, at the moment no using more than 5 device, but it is fine to streaming video (drama) without buffering. 

Huawei E8372, it needs usb power supply, so can consider as "portable" as long as u hv powerbank etc. U can get it from lazada or 11street at around RM230 too. So far i no yet using it, hopefully wont make me disappointed lar…

I'm using this as well, but not buy from China. There is a telephone port at the back but I never try to connect it since I'm using BB Plan only. You may try to connect a phone into that port and try to make call.
