Can I make international calls on long expiry mobile plans?

There are a handful of providers that offer either unlimited international minutes to selected countries or an allocation of how many minutes you can use on your plan to any country. Make sure to compare features between providers and their plans before signing up if this is an important feature to you.

Are 365-day prepaid plans the same as 12-month SIM only plans?

Yes, they're both the same. Some providers will refer to these as 12-month plans while others will call them 365-day prepaid plans. Keep in mind that some providers do offer 12-month contracted SIM only plans. These are different as you pay for your mobile bill monthly (rather than all upfront like a 365-day prepaid plan) and exit fees usually apply.

What happens if I don't use all my data up within 365 days?

Some providers do offer data banking as a feature on their 365-day plans. This can be unlimited or up to a certain limit. You'll just need to make sure to recharge your plan before it expires in order for the data to be rolled over. If your 365-day prepaid mobile plan doesn't come with any data banking feature, you'll lose your unused data at the end of the expiry period.

Can I get unlimited data on a 365-day prepaid mobile plan?

Unfortunately you can't on a 365-day prepaid plan. Unlimited data mobile plans are generally uncommon anyway and only felix offers a month-to-month truly unlimited data plan though the caveat is 40Mbps download speed caps throughout.

Is there a SIM card with data that doesn't expire?

No, there isn't. All SIM cards with data will eventually expire. The longest period to keep your plan running would be a 365-day prepaid mobile plan where you'll only need to recharge once a year.

what is the difference between telstra normal and wholesale networks

Finder

MariamApril 22, 2025Finder

Hi Grahame, Telstra’s main (retail) network covers around 99.5% of the population, including more remote areas. The wholesale network covers about 98.8%, so the difference is small but can matter if you’re in a more remote location. Hope this helps!

Hi Aboud, You’re in the good place to start – if you’re after low-fuss text and talk, a 365-day plan is a good option. But if you’d prefer monthly payments, check out our guide to cheap mobile plans.

I want a prepaid sim card (normal size) for the elevator phone, without an expiry date. Is this possible?

Finder

AngusOctober 22, 2024Finder

Hi Fiona, Alas, I’m not aware of any SIM card that has no expiry – it’s always going to need a plan attached to it to be active, and 365 days is the longest you can get in Australia.

Hi I am wondering what sort of plan my samsung 5pro will need please 🙏

Finder

AngusSeptember 20, 2024Finder

Hi Elita, Which plan you need will largely be determined by two factors: how much you want to spend and how much data you use. For most folks, 15GB a month is plenty, which means on a 365-day plan you’d be safe with 180GB. If you’re not sure, it might make sense to start with a shorter-duration prepaid plan and see how much you use in practice. Once you know that, you can pick a 365-day plan that has enough to cover you for a year. Hope this helps!
