Australian mobile phone plans

eSIM Only plans

At ZenSim, we made the call to only offer eSIMs and ditch the fiddly plastic SIM cards. That means every mobile phone plan at ZenSim is eSIM only. We think eSIM plans are the future, they're more secure, you can get connected within minutes (not days) and they don't require any plastic - that's right you don't have to worry about finding that little metal pin thing again. Oh we should also mention if you love to travel, eSIMs make life a whole lot easier if buying travel eSIMs. See our to check if your phone is eSIM compatible.

Prepaid mobile plans

All of our mobile phone plans are prepaid. That means you never have to worry about a surprise bill giving you half a heart attack. It's simple, you pay on the same day each month for the month which follows. You will never be charged for something without your knowledge. The even better news here is that if you take a trip overseas, you don't need to freak out about making sure you turn roaming off to avoid that several hundred dollar bill when you arrive back home (like some of our competitors are famous for).

5G mobile plans

If 5G is your vibe, our top-tier plans are calling your name! Our 70GB and 100GB endless plans come packed with 5G goodness, giving you all the speed you need for streaming, gaming, and scrolling to your heart’s content.

Prepaid mobile is our middle name...

Monthly mobile plans

At ZenSim, we decided to charge our customers monthly on the same date each month - it just makes sense! Some of our competitors and their 28 day billing cycles are a bit sneaky, because aside from having to pay your bill on a different day each month (annoying) you are also charged 13 times throughout the year (not 12 like with us). If we get mathematical here, a $50, 28 day plan would actually cost you $54.16 a month if you divided your total payments for the year by 12 (months) - I bet they didn't explain that on their plan page 😉

International roaming & intl. calling

We offer an international roaming pack for our customers who like to travel and want to get connected easily. The pack is available in 31 countries and can easily be purchased from within the ZenSim app - see our roaming page for more info. Also, most of our Aussie plans also include some international calling, we find this useful if you need to contact your Grandma and she can't work out how to call using Whatsapp or Messenger.

Mobile phone plan data banking

Save up a little data for a rainy day! Most of our plans include a 500GB data bank which is handy. How does it work? Any of your data which is not used up by the end of your billing cycle, will be saved for you in your data bank to be used in the future. When you have data in your data bank, it means if you happen to go over your plan data limit one month, you will begin to use your saved data bank data and be able to continue using your service as normal until your data bank is used up.
