The end-of-financial-year sales have seen many smartphone deals across flagship, mid-range and budget handsets, including some rare discounts on the current iPhone 17 range.

If you splurged on a new phone during the sales, you may be interested in signing up for a new SIM-only plan if you bought one outright, especially if you’re not 100% happy with your current provider.

Even if you didn’t buy a new phone, it can still pay to shop around for a new SIM-only plan, as you may find one that fits your needs better than your current one. You could be paying for a ton of data with your current provider that goes unused, for example. Or maybe you’d benefit from having international calls included in your monthly price.

Given how competitive the telco market is currently, providers are jostling for your attention — whether it’s generous mobile data allowances, discounts on the monthly plan fees or inclusions like international calls and texts — and it would be a good idea to take full advantage.

The best part is, unless your current plan is tied up with a mobile phone, it’s so easy to switch providers. If the promotional plan discount of the SIM-only plan you signed up has just wrapped up, you can easily swap to a different provider that’s offering its own discounted plan with next to zero hassle.

I’ve put together a list below of the best SIM-only plans I’ve spotted this EOFY across a range of use cases and budgets, with all the inclusions and discounts:

Best value EOFY SIM-only plan

TPG Large Plan | 100GB | AU$22.50 per 28-day renewal (first six renewals, then AU$45 per renewal)

While we’ve usually spruiked the TPG plan that’s a step down from this one (50GB data for AU$17.50 per month) as the best value SIM-only deal, getting 100GB of mobile data for AU$22.50 is an outright steal, even if it’s just for the first 6 months. Unlike many of the SIM-only plans at this price range, you get access to the full Vodafone 5G network, bringing with it added benefits of extended coverage and faster download speeds. One perk also worth mentioning is the inclusion of unlimited international calls and texts to 31 destinations. Do note is that this is a 28-day plan, which means you’ll have 13 payments each year.

Total minimum cost: AU$22.50
Total cost for first year: AU$405
Ongoing yearly cost: AU$540

Best cheap EOFY SIM-only plan

Best EOFY SIM-only plan on the Telstra network

Exetel PlusOne eSIM plan | 130GB | AU$40p/m

Exetel has only a single mobile plan offering, but the brand nails the brief perfectly with a great value option on the Telstra 5G network (with speeds capped at 150Mbps). You get a generous 130GB of data each month, unlimited international calls to 15 countries including the UK and US, and the ability to bank up to 1000GB of data. And all this for just AU$40 per recharge (30 days). Do note that this plan is only available with an eSIM, so you'll first need to check if your phone is compatible.

Total minimum cost: AU$40
Total yearly cost: AU$480

Best EOFY high-data SIM-only plan

Vodafone Large Plan | 400GB | AU$36.50 (first 6 months, then AU$73p/m)

Of the big 3 Aussie telcos, Vodafone has regularly provided the best value, and the mere fact that the brand made it to this list means that it can compete with MVNOs in certain price points. Vodafone is offering 50% off plan fees for the first 6 months, making the 400GB Large Plan, at less than AU$40 per month, the best high-data SIM-only plan this EOFY. To sweeten the pot further, you also get unlimited minutes to 'Zone 1' nations and 300 minutes to 'Zone 2' nations. To see which countries are available, you can learn more about international calls with Vodafone.

Total minimum cost: AU$36.50
Total cost for first year: AU$657
Ongoing yearly cost: AU$876

Best EOFY long expiry SIM-only plan

Lyca Mobile Large | 900GB | AU$220 (first 12 months, then AU$480)

Lyca Mobile's Large plan has long been TechRadar’s favourite long-term expiry plan, especially now the included data has increased from 600GB to 900GB (although the price did also increase from AU$175 to AU$220 for the first 12 months). Granted, the ongoing cost after the first year is quite pricey, but you at least have the option to shop around for a different promo on a long-expiry plan afterwards. The mobile data will be provisioned in 75GB instalments each month, which can be helpful in case you accidentally use too much data in a single month. You'll also receive international minutes to 35 destinations with this plan.

Total minimum cost: AU$220
First year cost: AU$220
Ongoing yearly cost: AU$480
