What is a mobile plan?
A mobile plan is a service agreement between you and a mobile network provider. In exchange for a monthly fee (or a prepaid amount), the provider gives you access to their network to make calls, send texts, and access the internet (data).
With many providers, you have the option to bundle the plan with a new phone, paying it off over a set period, typically 12, 24, or 36 months (handset repayment). However, SIM only plans (often called BYO or Bring Your Own device) are also very common, meaning you do not buy a phone with the subscription but use your existing device instead.
You can also choose whether you want a postpaid or prepaid plan. Put simply, with a postpaid plan, you receive a bill at the end of the month for your usage, while a prepaid plan requires you to pay upfront for your service, often without any credit checks or lock-in contracts.
How do I find the best mobile plan for me?
- Choose a provider with good coverage in your area. While major networks cover most of the population, regional coverage varies significantly. If you live in a rural or regional area, check the network coverage maps for the three major network owners – Telstra, Optus, and Vodafone – versus smaller providers (MVNOs) that use parts of these networks.
- Determine how much data you actually need. Check your current phone’s settings to see your average monthly usage. If you mostly use Wi-Fi at home and work, a smaller, cheaper data allowance (e.g., 10 GB – 20 GB) might be sufficient.
- Decide if you want a postpaid or prepaid plan. With a postpaid plan, you pay a monthly fee. Most SIM-only postpaid plans are now month-to-month (no lock-in contract), giving you the flexibility to switch providers anytime. If you choose a prepaid plan, you pay for the subscription in advance, and it ends automatically if you choose not to recharge
- Ensure the provider offers the support you need. If you want the ability to contact customer service by phone, ensure the provider offers this. Smaller providers sometimes only offer customer support via email or live chat to keep costs down.
- Choose the plan that best meets your needs. After evaluating all the factors above, you can compare prices among the plans that meet your requirements. This way, you will find not just the cheapest plan, but the one that offers the most value for you.
What’s the difference between postpaid and prepaid?
Postpaid plans are very common for those wanting stability. You pay your bill at the end of the month based on your agreement. Postpaid plans usually offer higher data allowances, 5G speeds, and features like “endless” data (speeds are capped after a certain limit). You generally need to pass a credit check for these.
With prepaid plans, you pay for your service upfront (“recharge”). If you run out of data or credit, the service stops or features become limited until you recharge again. There are no credit checks and no surprise excess usage fees. This is an excellent option for students, newcomers to Australia, or anyone on a budget.

How to get a mobile plan
- Compare offers in the table at the top of the page and choose the one that suits you best.
- Visit the provider’s website to order the plan.
- Choose your SIM type. With most providers, you can choose between a physical SIM card or an eSIM.
- Fill in the required details. You will need to provide valid identification (such as an Australian Driver’s Licence, Medicare card, or Passport) to verify your identity, as required by Australian law. If you are choosing a postpaid plan, the provider will likely also perform a credit check.
- Activate your plan. If you have chosen an eSIM, you will receive instructions on how to activate the plan digitally. If you have chosen a physical SIM card, the provider will send it by mail. Once you receive it, insert it into your phone.
- Start using your plan. You are now ready to go.
What is “Unlimited” data in Australia?
Many providers now advertise “Endless Data” or “No excess data charges,” but it is important to read the Critical Information Summary (CIS). Typically, these plans give you a set amount of high-speed data (e.g., 60 GB or 100 GB).
Once you exceed that limit, you will not be charged extra fees, but your speed will be reduced (shaped) significantly – usually to 1.5 Mbps. This is enough for music streaming and basic browsing, but may struggle with HD video streaming.
Frequently asked questions about mobile plans
Finding the best plan depends entirely on your usage habits. If you’re mostly on Wi-Fi at home or work, a small data allowance (around 10 GB–20 GB) on a SIM only plan will likely offer the best value. However, if you’re a heavy streamer or use your phone as a hotspot, you should look for mobile plans with unlimited data options. Always check the network coverage in your specific area – especially if you live in regional Australia – before committing to a provider.
The choice between prepaid and postpaid mobile plans usually comes down to flexibility versus convenience. Prepaid plans are excellent for budgeting as you pay before you use the service, meaning no “bill shock.” They often come with shorter expiry periods (typically 28 or 30 days). Postpaid plans are usually billed monthly and often include perks like international roaming credits or discounted device installments if you’re buying a new handset.
To find a cheap plan that still offers great service, look into MVNOs (Mobile Virtual Network Operators). These providers rent space on the major Australian networks but often charge significantly less for their mobile plans. The trick is to check which wholesale network they use. Some cheap options might have “speed caps” (like 150 Mbps on 5G), but for most social media and streaming, this is more than enough. Always use a coverage map to ensure the provider has “pings” in your neck of the woods.
In the Aussie market, unlimited data usually comes in two forms. Some mobile plans offer a speed-capped unlimited service, where you get a set amount of high-speed data, and once that’s used up, your speed slows down (often to 1.5 Mbps or 2 Mbps) for the rest of the month. Other premium mobile plans offer truly unlimited data at higher speeds. Make sure to read the Critical Information Summary (CIS) to see if there are any speed restrictions that might affect your browsing.
Yes, many providers now offer “data banking” or “data rollover.” This means any data you don’t use during your current billing cycle gets added to a “bank” for the next month. This is a great way to get more value out of your plan. Some providers allow you to bank hundreds of gigabytes indefinitely, while others might have a cap on how much you can store or an expiry date on the rolled-over data.
Absolutely. By 2026, almost all major Australian telcos and many budget-friendly MVNOs offer the choice of an eSIM when you sign up for a new mobile plan. Selecting an eSIM allows you to activate your service almost instantly via a QR code or app, bypassing the wait for a physical card in the mail. It’s also a great way to have two mobile plans active on one device – perfect for keeping your work and personal numbers separate on the same phone.
