Approaching level 5

Me too, level 5 in like 2 days probably.
I will stop after. No advantages to go faster earlier than the 2 years that each bonus last.

I am also close to level 5. Not much point going much beyond that unless you make it a vocation.

Seems so far away for me, still working on level 2. Found this from HugoLH

You will have 3 slots. That's the biggest advantage I guess.

Three slots is great. I use them for (1) 500MB extra; (2) free voicemail [although I think they dropped that upgrade], and (3) 1$ rebate on mobile plan.
