Best Phone Plans in Australia 2026: Cheap SIM Only Deals

With so many phone plans available in Australia it can be overwhelming to choose the right one. We've compared dozens of plans across all major carriers and MVNOs to find the best value SIM only deals in 2026.

Best Budget Plan: Boost Mobile

Boost Mobile runs on the Telstra network — Australia's largest — at a fraction of the price. Their $30/month plan offers 25GB of data, unlimited calls and texts, and international calls to selected countries. For budget-conscious users who still want reliable coverage this is hard to beat.

Best Mid-Range Plan: Optus

Optus's $45/month SIM only plan offers 60GB of data on their 5G network. With nationwide 5G coverage expanding rapidly, this represents excellent value for data-hungry users. The included international roaming credits are a nice bonus for travellers.

Best Premium Plan: Telstra

If coverage is your priority, Telstra's network reaches more of Australia than any competitor. Their $65/month plan offers unlimited data with speeds capped at 25Mbps — more than enough for streaming and browsing. The included Apple TV+ subscription adds extra value.

Best Value MVNO: Woolworths Mobile

Woolworths Mobile runs on the Telstra network and offers competitive pricing with the added bonus of Everyday Rewards points. Their $30/month plan with 40GB is outstanding value for Woolworths shoppers.

How to Choose

Consider your data usage first. Check your current usage in your phone settings — most Australians use between 10-30GB per month. If you travel regionally, prioritise Telstra network coverage. If you're mostly in metro areas, any of the major networks will serve you well.
