FlexiSIM


What does it cost?

The Australia Post FlexiSIM costs $4 (inc GST) but you’ll get $4 discounted off your first 30-day plan payment or your first voucher purchased at the same time.


You can select from three 30-day plans - $19, $25 and $35 (inc GST). 

Can I change plans?

There’s no lock-in contract with FlexiSIM so you can change plans. If you want to move to a lower-cost plan, you can do so at the start of each 30-day billing period. If you want to upgrade your plan (for example if you use up your data), you can upgrade during the current billing period by paying the difference between your existing plan and the higher plan and you'll receive the difference in data and international talk minutes.

Can I keep my current mobile number when moving to Australia Post FlexiSIM?

Yes. When you activate your SIM, you can request to transfer your existing mobile number from your existing service. 

Do you have 5G?

5G is coming soon.

Do you offer data sharing?

Yes, you can share data with family or any user who is on the same billing account in Australia. For more information view the Sharing data FAQs.

Do you offer data gifting?

Yes, you can gift data only to other Australia Post Mobile FlexiSIM users – 1GB per gift, up to a max 5GB per billing period. If you have less than 1.5GB of data, you cannot gift your data. For more information view the Gifting data FAQs.

What if I exceed my data usage?

We’ll keep you updated on your data usage with text messages advising you when your data usage reaches 50%, 85% and 100%. 


If you reach 100% of your data allowance included in your selected plan, you’ll still be able to make and receive calls and send texts, but you’ll be unable to access data. You can choose to buy additional data at $10 per GB to get through to the end of the current billing period or upgrade to a higher plan by paying the difference between plans and receiving the difference in data and international talk minutes.

What's the FlexiSIM network coverage in Australia?

Australia Post FlexiSIM is provided by TravelSIM Australia using the Optus network. Optus provides unrestricted access to its network under its wholesale arrangements and offers extensive coverage (as at 31 March 2019 Optus had 98.5% 3G mobile reach to population and 97.3% 4G Plus population coverage).

Sharing data


Who can I share data with?

You can share data with up to five FlexiSIMs within your account.

How does data sharing work?

From the Data Sharing section of My Account, you can select what portion of each FlexiSIM's data to add to a data pool. Once your own data allowance has been consumed, you will start using data from the shared data pool. As the current billing period progresses, you can contribute more data to the pool for other FlexiSIMs to use.

What if I don't want to share data with all SIMs in my account?

If you don't want a SIM to access the shared data pool, that SIM will need to be removed from your account. Contact Customer Support for this request.

Who can change the amount of data shared?

Only the primary account holder has access to all SIMs under their account to select data amounts to add to the shared data pool.

What if all data within all accounts is used up?

If the shared data pool is used up and a SIM has no more data, the other SIMs have the opportunity to add more data to the pool or the SIM with no data can add 1GB of data to their own account for $10.

What happens to unused data?

Any unused data expires at the end of each billing period. Data is counted in kilobytes and includes uploads and downloads.

Gifting data


How do I gift data?

You can gift 1GB of your data to any active FlexiSIM with to a maximum of 5GB per billing period. You must have more than 1.5GB remaining to gift data. 

- Go to My Account and navigate to Data Gifting. 

- Enter the recipient's FlexiSIM mobile number and click 'Gift'. 

- Once gifted, the data will be appear in your account as data used. 

- The recipient can use the gifted data when their own included data has been used up. 

- Gifted data does not rollover between billing periods.

What's the difference between 'Data Gifting' and 'Data Sharing'?

Data can only be shared with SIMs on the same account, while gifting allows you to send 1GB of your unused data to anyone with an active FlexiSIM.

What is the expiry of the data I gift?

Data you gift will be added to the recipients data allowance and expire at the end of the recipients billing period.

Who can I gift data to?

Data can be gifted to anyone who has an active FlexiSIM.

If I use my data up, can I get my gifted data back?

Data can be gifted to anyone with a FlexiSIM and the recipient can gift the data back in the same way.

Billing


How do I pay my bill each billing period?

During activation, you can pay using a voucher purchased from a Post Office or with a credit or debit card. If purchasing with a credit or debit card, you have the option to save the card details for easier future payments as well as selecting to Auto Renew at the end of each billing period. If you activated with a voucher, you have the option to pay for your next billing period with another voucher or choose to pay with a credit or debit card.


Your next plan needs to be paid for during the current plan’s validity period to ensure your service is not interrupted. As your service is paid upfront, you will not receive a bill, however, we will email you to when your plan is nearing it's end.

What happens if I don't have a credit card saved?

We highly recommend that you have a credit card saved in your account to ensure an uninterrupted service. Once your 30 day billing period has ended, if you've not made payment to continue your service, the service will be suspended and you won't be able to send or receive calls, sms or use mobile data. Four days after your account is suspended and you haven't recharged your account with a voucher or resumed your plan with a credit card, your SIM will be barred and your number will be placed on hold for a period of 180 days. If you resume your service within this 180 day period, your number will be reactivated. After 180 days, to resume a FlexiSIM plan, you will need to order a new SIM card which will come with a brand new phone number.

What if I use up all my data?

When your data limit has been reached, you'll have the opportunity to add 1GB of data for $10 or you can choose a new plan with a higher data limit. Simply pay the difference and receive the difference in data and international talk for the remainder of the current billing period.

How do I change my plan?

Log into your account and select 'change plan' from the manage plan section. Plans with higher data allowances will start immediately giving you access to your new data allowance straight away, while switching to a plan with a lower allowance will switch when your current 30-day billing period has ended.

Can I have more than one SIM on my account?

Yes, you can have additional SIMs on your account by logging into that account during activation. While additional SIMs can be used by other people, all SIMs will use the same billing cycle.

How do I change my address or phone details?
