Just received an email this morning. This changes makes this plan even sweeter despite the plan expiry reducing to 28 days.
Can't seem to find a link directly to their website with this info through mobile.
Here's the info from the email:
we just want to let you know about some upcoming changes to your unlimited plan.
Your included data will be increasing from 5GB to 7GB. Plus, we've added unlimited standard international calls to 10 selected countries to your plan.
As well as this, plan expiry will be changing from 30 days to 28 days. You’ll still pay $39.90 per renewal and all your other inclusions will stay the same.
You don’t need to do a thing. These changes will take effect on [renewals from] 31 March, 2016
What are the 10 selected countries?
China, Hong Kong, India, Malaysia, NZ, Singapore, South Korea, Thailand, UK and USA.
Referral program seems to have been shelved (for now?)

not much of a deal a you are paying 13 times a year with this 28 day months.
techguides did a good looking into this and yeh it looks like you save a bit but that extra payment kills thhe deal.
