Hey, so I have a nexus 5 running on the 30 dollar unlimited data plan from tmobile. The plan says its "unlimited" but only includes 5gb 4g LTE data. I was wondering if the data would be still deducted if I changed my perfered network on my nexus from 4g LTE - 2g so I am only getting 2g speeds. Even though I shouldn't be using up any of my high-speed data, my data usage on the T-Mobile website still says I'm using 4g data!? What's going on!?!?
