Isnt that a good counter offer? What was your previous plan?

Wow. You said no to such a good deal from Digi?

As for the 50mb, if you don't see it in the app, it probably means that the 50mb have been used up, most likely when you were trying out the app online initially. Your balance for the 20gb probably now reads as lower than 20gb, like in 19 point something, correct?

For two of my sims, where the 20gb is in full, the 50mb count is showing at balance of 48mb left. For the other three where the 50mb count doesn't show at all, the 20gb count is 19.81, 19.91 and 14.51 respectively. Yes, I have been happily using up the 20gb in earnest for one sim! 

not necessary as i use one apps to login 10 sim cards from two mykad
and some more some not able to collect it due to scanning problem and gave up to collect
very ugly ler...
unlimited speed or 5Mbps?

Light user ok, medium to heavy is definite no-no.

I see you are from kk, do report back how's the speed. mine even on 4G in some areas getting only 1.5mbps on average, some places that can connect at higher frequency bands seems to be performing about 20mbps and above.
