Which is the best SIM in Australia?

This will largely depend on your budget, data needs and network preference. Fret not though. We round up the best SIM only plans every month across a bunch of categories, taking into account the latest promotions and discounts available.

Can I use my SIM only plan for data only?

Yes, you can use a SIM only plan for data only. Just keep in mind that if you're hotspotting to another personal device any excessive use such as downloading large files over an extended period may be flagged with the provider. You can compare high-data SIM only plans to match your needs. Alternatively, you could also consider a mobile broadband plan which works anywhere you can get mobile signals.

Is it better to buy a phone on a plan or get a SIM only plan and buy it outright?

This depends on what your budget looks like. Buying a phone outright will usually be cheaper since you can then pair your handset with a SIM only plan from any provider. Buying a phone on a plan is easier on the pocket as your repayments will be made over 12, 24 or 36 months. Phone plans are also primarily offered by Telstra, Optus and Vodafone so you'll always end up paying more in the long run as their SIM only plans are generally more expensive than those offered by smaller providers.

Can I get a SIM only plan for my Apple Watch?

You will need a GPS + Cellular model of the Apple Watch to get a SIM only plan that comes with an eSIM feature. For now, only Telstra, Optus and Vodafone allow you to set up a phone plan for your Apple Watch. According to Apple, you need to use the same carrier for both your iPhone and Watch. Depending on the telco, you'll pay anywhere between $5 and $10 a month to sync your number.

Why are Telstra SIM only plans so expensive?

Thanks to Telstra having the widest network coverage in Australia, it can kind of justify having higher price tags too. The telco also offers a lot of extra features on its mobile plans including free entertainment trials and some international inclusions. If Telstra's SIM only plans don't fit your budget, you can still access its network via an MVNO. You'll get similar coverage for a lower price. The majority of Telstra MVNOs run on Telstra's wholesale network which reaches 98.8% of Australians. Boost Mobile is the only provider to have full access to Telstra's coverage which reaches 99.7% of the population.
