Guy wanna ask a question.my house got no streamyx thus i'm looking for alternative

Been trying to use 3g sim router using the xpax turbo.however,noted that after prolonged use,noted speed slows down.

My question is,does the celcom xpax slow down/limit the speed if it knows we are using it as a mobile broadband/wireless hotspot??

That might be the case. But the weird part is i just tried at 3 situations

1)using my 3g sim router huawei b68l
-speed okay. Speed test 4mbps intially. Then after around 20 min drop to around 0.1mbps

2)using my phone as portable hotspot (nexus 5)
-similar to the above

3)uaing my phone (nexus 5) without any hotspot or router
-np at all. Using lyt.net now as we speak.

Its as if it knows i'm using hotspot and decides to slow down the speed
