Hey, qktreasures! Man, that BTV acronym brings back some memories! We offered "Bridge to Value" features and plans when we were in the middle of transitioning from the old two year contract/"subsidized" device model to the more straightforward no-contract, full price phone set-up we have today -- basically, when we were becoming the Un-Carrier!
I'm glad the plan's still working for you! I am super stoked to read that there have been some promos you've been able to take advantage of; although I understand that others might have a limitation of only working with newer plans (because in many cases these grandfathered plans already offer a great value). Hitting that line max is tough, though, and oooo those taxes! Maybe we'll have an offering in the future that will get you the same or better features around this price -- I'll try to keep you and this post in mind if I see any deals that look really good! Thanks for sharing, and for being a T-mobile customer for so long. <3
