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 plans offer voicemail or Message bank?

Finder

Hi Guy, most plans offer voicemail or a message bank. Once you decide on a plan just double check on the provider’s website to be sure or you can reach out to me again and I;ll give you a confirmation. Hope this helps!

what is the difference between Vodafone 365 plan $45 & $55 plan

Finder

MariamJune 11, 2025Finder

Hi Imad, a 365-day plan means you pay the full amount upfront and don’t have to think about your mobile plan for a whole year. It often ends up cheaper than paying month to month, as long as you’re happy with Vodafone’s coverage and what’s included.

The $45 and $55 plans run on a 28-day expiry, so you’re essentially paying monthly and can cancel anytime. The main difference is the amount of data you get. For most everyday users, the $45 plan should be enough. But if you use a lot of data, the $55 might suit you better. Hope this helps!

Can I keep my mobil number

Finder

MariamMay 9, 2025Finder

Hi John, yes, you can keep your mobile number if it’s under your name. If it’s not, you’ll need to transfer the ownership to your name first. When you sign up, they’ll ask if you want to keep your existing number – just select ‘yes’ when prompted. Hope this helps!

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!
