My GoSurf 499 MB allocation which is part of my Lifestyle Plan 999 is already used up with 2 weeks remaining in my cut off period. I usually register to GoSurf 50 (3 Days 1G) when this happens but right now the process won't push through. I am thinking if i can add additional Gosurf 499 (1G/30days) in my plan promos, would it stack? i mean going forward is it going to be added to my monthly data Cap? is it possible even?
