48M users have been asking that since 2015 and the answer is still "no but maybe in the future"..starting to sound a bit lame at the tail end of 2018...
I using 48 for a while now and can say 3g (if coverage is decanted) is enough to watch full HD video. And I have a feeling we will get 4g eventually. To be honest, I would like to stay on 3g for the same money, then 4g for more. As I said earlier 3g is fast enough. I often share it with a laptop.
(if coverage is decanted)
I presume you meant "decent"?
BTW it's not 3G that 48 provides but up to "3.75G" (H+).
Hope this helps.
