You may not have heard of this small Australian telecom operator yet, but Circles.Life is known for offering extremely competitive SIM plans that work on the Optus 4G network. As part of this week's Click Frenzy, the provider is offering a pretty unforgettable discount. Circles.Life is cutting the price of its SIM-only plans by AU$10 per month for up to 12 months, which means you can set up with 100GB of data for just AU$28 per bill instead of the usual AU €38, and you will benefit from the reduced price for one year. If you don't need that big 100GB data store, you can choose 20GB of data for AU$18/m for 12 months, or 8GB for just AU$8/m for six months, which is incredible value. But you'll have to be quick if you want to make this deal, it's available starting today (November 9) and ends at 9pm on Friday, November 13. If you opt for 100GB or 20GB of data, enter code SUPERFRENZY at checkout, or to withdraw AU$10 from the 8GB plan, enter code JOINTHEFRENZY. Depending on the plan you choose, these discounted prices are only available for a maximum of 12 months with Circles.Life, after which each will increase by AU$10 to your regular price. However, since these plans come without a lock-in contract, you can opt out at any time without paying any fees. Each plan also includes unlimited talk and text to standard numbers in Australia, but if you want to make international calls you can add 300 minutes to select countries for an additional AU$5 per month at checkout. Circles.Life also offers ``bill crash protection,'' which means you'll get a 3GB data buffer at no extra cost if you nibble on your monthly amount. You will be notified once you use this buffer, so you should not incur any unexpected charges. The telco runs on the Optus network, so you can expect good coverage from their 4G Plus network.
