I noticed a chance to data clock kicks in tomorrow and hadn't seen anybody mention it on here. Clearly there must have been a few too many people using the $6 day pack as a permanent Internet connection!
You only get 40GB per month at full speed now before being limited to 1Mbps.
Important update: We’re all about fighting for fair. We want to make sure our network doesn’t slow anyone down. That’s why from 15 April 2019 Data Clock max speeds will be reduced to 1Mbps after 40GB/month, to stop anyone hogging the fast lane.
