Optus goes one better than its Virgin Mobile subsidiary with data rollover on new plans.
Most of the business mobiles we know are on postpaid plans - because running out of credit is as frustrating (and revenue-killing) as a flat battery. But prepaid plans do make sense for some users, and auto-recharge facilities can practically eliminate that risk.
In March, Virgin Mobile introduced data rollover on postpaid plans, but what that actually means is that unused data from one month can be rolled over to the next, but the new month's data has to be used first. So the upper limit for any month is twice the normal allowance, and that was only achievable if you used no data at all during the previous month.
Now Optus has introduced a new prepaid plan called My Prepaid Monthly Plus that provides a more generous data rollover scheme. Providing you recharge before the credit runs out, up to 10GB of unused data will be rolled over. If your mobile data use is very irregular, this could be a big benefit.
Three recharge levels are available, all lasting 30 days and including unlimited minutes to Australian landlines and mobiles, 13 numbers and voicemail, as well as unlimited national SMS and MMS.
The $30 recharge includes 1.5GB of data and $5 credit towards extras such as international calls, roaming charges and premium services.
$45 gets you 3.5GB of data and $10 of extras, while the top-end $60 recharge takes it up to 6GB and $15 of extras.
Data top-ups cost $5 for 500MB, and last 30 days.
For comparison, Optus's postpaid My Plan Plus starts at $40 for the same unlimited calls and messages, but only includes 500MB of data without rollover. To get 6GB of data you need the $80 plan, but that also provides up to 300 minutes of calls to certain overseas countries.
Or there's Amaysim, which uses the Optus network. Its $44.90 Unlimited 5GB plan also offers unlimited calls and messages, as well as - yes, you guessed it! - 5GB of data.
