So if history repeats itself do you think T-Mobile will get rid of their truly unlimited data once their network starts to get congested? I personally don't think this will happen because from what I've read it seems that this new plan is helping them a lot. Sprint just showed off their guarantee which is interesting, I think that Sprint might actually stop doing the unlimited data because of that guarantee. I'm on a grandfathered plan with AT&T and because their coverage is still better than T-mobile I am hesitant to switch all of my lines. My test line which I did switch to T-mobile is doing ok, luckily I am in a LTE market but AT&T is still better. The thing is though that if T-mobile gets better I might just switch all of my lines to T-Mobile and just hope they never throttle (like AT&T) and don't get rid of the plan. Just don't want to miss a good opportunity. What do you guys think?
