Find the best mobile plan for your kids
We understand that staying connected with your kids wherever they are is a top priority.
If you're a parent looking to get your kid or teenager on the right mobile plan, here's a breakdown of some key points to consider.
1. Don't pay too much
You don't want to be spending a fortune on your kid's mobile plan. These days, most plans come with unlimited talk and text, so it's really just data you need to look out for.
Prepaid plans can be a great way to limit spending for your kid so you don't get hit with excess charges.
Long expiry plans can also be good value for money (and possibly cheaper overall) but you're going to have to commit to a minimum of 90 days.
2. Keep an eye on data usage
If your child's big on streaming and video calling on the go, you might want to consider opting for a decent data allowance instead of paying excess charges or topping up data on the fly.
The good news is that most mobile plans come with no lock-in contract these days, so you can always switch to a plan with more suitable data inclusions if one doesn't work out.
3. Check the provider's mobile app
To make sure your kid isn't going overboard on using the Internet while they're out and blowing through their mobile plan inclusions, consider providers that offer a user-friendly mobile app.
These apps can track your kids' data usage to help you avoid excess charges and make use of other features such as recharging your plan.
4. Cyber safety features
If you're worried about your child's safety online and how much time they spend on their screen, you can sign up to specific mobile providers that offer features to address your concerns.
Optus and Woolworths Mobile both offer family-friendly features across some of their mobile plans:
Optus offers free access to The McAfee Safe Family App on the Optus Family Plan or Optus Kids Plan. This will help you with content restrictions, screen time rules and location tracking.
Woolworths Mobile has partnered with Family Zone to help parents keep track of how their kids are spending their time online. All you have to do is download Family Zone's mobile app to control what your child can access online. It'll also help you manage their screen time and track their device.
There are also a number of other apps available to help you ensure your child's safety, both online and offline, ranging from making sure the content they're viewing is safe to locating their device.
How does Finder's value scoring system work?
For certain categories, we use a value scoring system to choose the best mobile plans for kids and teens by scoring the following factors:
Cost per gigabyte. This is calculated by taking the price of the plan over 12 months divided by the amount of data (GB).
Network coverage. We awarded scores depending on how wide the network coverage is across Australia.
Data rollover. We weight providers that offer data rollover higher than those that don't have this feature.
International calls. This includes those that offer unlimited calls or credit/minutes for international purposes.
Wi-Fi calling. We weight providers that offer Wi-Fi calling higher than those that don't have this feature.
We then assign a weight to each of the factors in order to calculate a value score. Price and data are given the highest weighting.

Frequently asked questions
Both prepaid and postpaid plans come with different advantages. The best type of mobile plan for your kid will largely come down to how restrictive you want to be.
Prepaid plans are set up so that once the plan's inclusions have been used up, you'll get cut off until you recharge your plan again. This means you won't have to worry about getting slammed with excess usage fees.
Postpaid plans guarantee that your kid won't be left stranded without any mobile data while they're out and about. On a postpaid plan, if you use more data than allocated on your plan, you'll automatically be charged extra so you can continue to use your plan as normal.
Family mobile plans allow you to have all your family's mobile plans from 1 provider under 1 account. It makes for easier management when it comes time to pay your bills.
While it might help with keeping organised, the lack of plan controls available on most family plans could be problematic. With family plans, all the data across the different mobile plans become pooled together. This gives your kids the opportunity to use up all the data themselves.
We think getting your kid their own mobile plan could be a better way to go. This way, you can limit their usage and not stress over your data disappearing suddenly.
If you're looking for a more affordable way to get your kid a smartphone, you can consider signing up to a phone on a plan.
Instead of forking out hundreds or thousands of dollars outright, getting a phone on a plan breaks down the cost of the phone over monthly repayment periods.
Just keep in mind that plans that come attached with new phones are often more expensive than SIM only plans. This option may not be the best for those with tighter budgets at the forefront of their minds.

Important information about this website
finder.com.au is one of Australia's leading comparison websites. We are committed to our readers and stands by our editorial principles
We try to take an open and transparent approach and provide a broad-based comparison service. However, you should be aware that while we are an independently owned service, our comparison service does not include all providers or all products available in the market.
Some product issuers may provide products or offer services through multiple brands, associated companies or different labeling arrangements. This can make it difficult for consumers to compare alternatives or identify the companies behind the products. However, we aim to provide information to enable consumers to understand these issues.
We make money by featuring products on our site. Compensation received from the providers featured on our site can influence which products we write about as well as where and how products appear on our page, but the order or placement of these products does not influence our assessment or opinions of them, nor is it an endorsement or recommendation for them.
Products marked as 'Top Pick', 'Promoted' or 'Advertisement' are prominently displayed either as a result of a commercial advertising arrangement or to highlight a particular product, provider or feature. Finder may receive remuneration from the Provider if you click on the related link, purchase or enquire about the product. Finder's decision to show a 'promoted' product is neither a recommendation that the product is appropriate for you nor an indication that the product is the best in its category. We encourage you to use the tools and information we provide to compare your options.
Where our site links to particular products or displays 'Go to site' buttons, we may receive a commission, referral fee or payment when you click on those buttons or apply for a product. You can learn more about how we make money.
When products are grouped in a table or list, the order in which they are initially sorted may be influenced by a range of factors including price, fees and discounts; commercial partnerships; product features; and brand popularity. We provide tools so you can sort and filter these lists to highlight features that matter to you.
