Unlimited Mobile Tether help?

Currently I signed up for the unlimited mobile Hotspot from t mobile. After about 30 GB my speed was slowed down to 128 KBps. Can anyone give me or direct me to a guide of how to set up my mobile tethering so that it will actually be unlimited? I'm on 4.4.4 and I'm rooted. I've been looking for some help but all of the things I've seen have either been very complicated or hasn't worked. For example the PGA.net installer didn't work on my pc for whatever reason.

Thank you.

Samsung S4 (I9505) Not connecting to a mobile network after flashing new ROM)

Okay this is a very long story. I have had this old S4 in my drawer and decided to update and refresh it. I found on SamMobile that lollipop was available for it, so I downloaded that. After flashing that to my S4 the phone could not detect a sim card. I then suddenly realized I had flashed the wrong ROM. I live in Australia and I am connected to a carrier called Telstra, but instead of flashing that one I flashed a ROM meant for unlocked phones. So now I am in trouble and I need your guys help! Please help me out on this and if you need any questions to help me just ask! :)
