I am currently with Xtra, 20GB adventure plan that costs me $61 (due to GST increase). Which provides with satisfying speeds, but the the data caps are too low... I am considering joining Slingshot's 20GB plan with a data block of 20GB, totalling $65.
However I am worried about reduced speeds and consistency that some people are talking about online and offline. Or should I just try my luck with doubling data caps like some people did in this forum?
