We're big fans of prepaid and no-contract plans here at Lifehacker. The SIM-only plans on offer from Jeenee Mobile stack up pretty well against the competition, offering 4G access to the Optus network and decent data allowances.
Jeenee operates as a social enterprise -- it uses its profits to help fund communication services for disabled Australians. But regardless of its motives, the plans are impressive.
The $15 a month plan is relatively unremarkable, since it only offers 250MB of data and $200 in credit for both calls and texts. The $25 deal is better: it includes unlimited texts in Australia, 1.5GB of data and $500 in call credit -- enough for 232 2-minute calls. If you're not a particularly heavy data user (the average Australian uses around 650MB a month), this could be adequate.
For $35 a month, you get unlimited Australian texts, $650 in credit and 3GB of data. (Note for fiscal completists: the charge for your SIM card and to set up the account is $20.)
How does that weigh up against other companies reselling the Optus network? Optus itself charges $45 a month for a plan with 2GB of data, and unlimited Australian calls and texts. For the same amount, Amaysim ups the data volume to 5GB, but doesn't offer 4G. Vaya's $45 plan only includes 2GB of data, and doesn't have unlimited calls or texts. That makes Jeenee a pretty decent deal if you aren't going to need unlimited calls.
