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.

Lyca and Kogan both have cheap long expiry plans that run on the Vodafone network, so those could be worth having a look at.

What are the strings attached to the Visa gift card by purchasing Optus 365 days prepaid mobile sim from Finder website?

Finder

AngusDecember 22, 2025Finder

You can use the Visa gift card anywhere Visa is accepted. To get the $150 card, you need to sign up for the 365 day plan and must not have been an active Optus customer in the last 30 days. The full terms and conditions are explained in more detail here.

Hi John, once you buy and activate the SIM, you’ll have the option to either port an existing number or sign up to a new number. Choose the latter. Hope this helps!

Why is 12 month plan so dear

Finder

MariamNovember 10, 2025Finder

Hi Kevin, it is a slightly bigger chunk of your money upfront but they can work out cheaper than some month-to-month plans. If you prefer paying a smaller amount each month, you can compare monthly plans and filter out options based on your budget: https://www.finder.com.au/mobile-plans. Hope this helps!
