So, Optus has a $60 / mon plan ("SIM-only plan" in its Jan 2015 magazine), with a "Data Bonus" which lifts the monthly mobile data quota to only 6 GB, ie, $10 / GB, if only Data were of interest… unlikely.
I describe a way to reduce the cost of data - for large, even usages - to $4 / GB.
I'm clearly NOT referring to that plan… Instead, I'm thinking of one of the (quite legitimate, IMO) ways one can get value from one of Optus' MyPrePaid offerings:
- Pay $2 / day, across 30 days (ie, $60 for the period) on MyPrePaid Daily Plus
For each of the 30 days, you'll get 500 MB (ie, ~ 0.5 GB, or ~ 15 GB across 30 days)
One obvious limitation is that - to avoid doubling some of your daily costs, you won't want to use more than 500 MB on any one day; but - if you choose to do that - paying another $2 will add 512 MB (from memory) to your data quota. Could be useful.
In addition to data, of course, you get unlimited SMS / MMS sends, and unlimited calls out, withing AU, to normal tel.no.'s, including 13 / 1300 no.'s.
Same $60 you'd pay - per month, instead of per 30 days - for 6 GB (to use across each month), but almost 15 GB, ie, well over twice the 6 GB alternative.
Of course, you should read "up to" before each data amount, above. Once the month (or each day of the 30 days) passes, you lose any unused data for that month (or for each day).
(Now, it you need LOTS more mobile data, you could pay up to $4 for up to 1 GB - per Day - across those 30 days, & get up to 30 GB forn $120.00.)
DISCLAIMER: I've onky done the arithmetic to get the above costs, &, hopefully, correctly! I leave - as an exercise for the Reader - to check all the conditions, eg, Reasonable Use clauses, etc. eg, in Optus' agreements, Critical Info Summaries, etc. Also: IANAL.
Enjoy all that mobile data, while out & about. :-)
I actually read all that, definitely seems viable to me. Would be one of the best deals for 4G data around.
