EXCITING NEWS for Straight Talk Users Regarding Data Throttling

So I'm very excited to report that I have used 35 GB of high speed data this month on straight talk :D

So, it's unlimited, but only kind of. What happens is, the preferred network type setting in CM 12.1 does a really good job and, as long as you stay on LTE (and you might have to keep an active connection too), you have unlimited high speed data. As soon as I dropped into 3g, my data started being throttled.

This is very exciting because, in theory, as long as you live in an area with good LTE coverage, you could theoretically have mostly unlimited high speed data. I am not sure how this little bug works if you switch from one LTE tower to another (this was all done at my house).

I would like some feedback. Please let me know if you try any of the following:
1. Try this on CM 12.1 for yourself and make sure this isn't some fluke that just happened to me this month
2. Try this on ANY other ROM. I don't know what will happen, but I would assume this would work on any CM 12.1 based ROM with the LTE only setting.
3. Can we get something to FORCE our phone to stay on LTE if this is legit? I would rather have LTE than long battery life.

Evading T-mobile Throttling on S6

Background:
I love t-mobile and don't wish them harm but I have been having some problems with how fast my 4g data disappears. I am on a grandfather plan that got upgraded. For one extra buck I could have 30 MB of data plus Music Freedom. Despite trying a bunch of firewall's and data restrictions and doing nothing but listening to Spotify the data never lasts more than a few days. And then it's edge speeds which make listening to spotify even on the lowest setting a buffering nightmare.
Question:
How do Increase the amount of data by just a little (I only need like a extra 100 MB) without paying a ridicules a month?
Possible Workaround:
Editing services.jar, I don't know if this method still works on t-mobile or if it still works on new phones like the s6 which I own. I am going to try the method on this thread http://forum.xda-developers.com/show....php?t=2057344 on the weekend. If anybody could tell me some more recent updated or some tips on the process above info that would be great.
