Save 66.6% on an amaysim prepaid plan for Halloween

amaysim is looking to spook the competition with a deal on its $30 Unlimited mobile plan.

If you're in the market for a new mobile plan, the Optus MVNO's latest promotion is more than just eye-catching. Rather than pay the usual $30 per month for the SIM-only plan, signing on for your first month with amaysim's $30 Unlimited plan currently costs just $10. 

However, don't let the name lead you astray. amaysim's $30 Unlimited plan includes unlimited calls and texts, unlimited international calls and texts to 42 countries and unlimited data banking. It does not include unlimited data, or even the kind of unlimited speed-capped data you can find through alternative mobile plans from providers like Vodafone or felix.

Instead, the plan includes 30GB of data as standard. Courtesy of the aforementioned data banking, any unused data will roll over into the next month. If your data habits lean towards frugality, it won't take long for that balance to add up. What's more, for the duration of this promotion, amaysim is throwing in an addition 25GB of data in the first month. All told, that makes for a total of 55GB for the first month.

While the amaysim $30 Unlimited plan does revert to the usual 30GB per month after that initial 28-day recharge, the data banking here means you'll have plenty of time to use up the additional gigabytes on your own time. Getting more and paying less is the name of the game here.

You're out $10 rather than the usual $30, and you're getting an extra 25GB of data on top of the usual 30GB. These bonuses disappear after the first renewal. Fortunately, this is a no-contract plan. You're free to leave or shop around after that point if you're keen to make the most of your budget.

This promotion runs until October 31.
