Step 1: Check which network covers your area
Coverage is the single most important factor. In Australian metro areas, all three networks (Telstra, Optus, Vodafone) perform well. If you live or travel in regional or rural Australia, Telstra's coverage advantage is significant — which makes Boost the better pick despite the lower data inclusion.
Step 2: Estimate your monthly data usage
The average Australian uses around 10–15 GB per month on mobile. If you're on Wi-Fi at home and work, 7–15 GB is often enough. If you work remotely, stream on mobile, or use a hotspot for your laptop, you'll want 30 GB or unlimited. A quick check of your current bill's data usage will give you the answer in seconds.
Step 3: Decide on contract vs prepaid
All three plans above are no-lock-in prepaid — you're not trapped. You can switch providers without penalty at any time. This is the key advantage of MVNOs over the major carriers: freedom to leave whenever a better deal appears.
Step 4: Consider your international calling needs
If you call family overseas regularly, factor that into your comparison. Amaysim includes international calls in many plans. Others charge per minute or require an add-on. A plan that looks cheaper may cost more in practice once international minutes are added.
Why MVNOs Are Almost Always Cheaper Than the Big Three
Telstra, Optus, and Vodafone charge a premium for their brand, retail stores, and postpaid infrastructure. MVNOs rent the same network wholesale and pass the savings on to customers. You're not sacrificing coverage — you're cutting out the overhead. The trade-off is typically less customer support, no in-store service, and sometimes slightly lower priority during peak congestion.
What About 5G?
All three providers above support 5G where the underlying network has 5G infrastructure. In practice, 5G coverage in Australia is still concentrated in major metro areas and expanding. If 5G speed is a priority, check the 5G coverage map for your specific postcode — availability varies significantly even within cities.
Quick answers
What's the cheapest prepaid plan in Australia in 2026?
Boost Mobile's $18 first-month promo is the cheapest entry point, but the ongoing price is $26 for just 7 GB. For ongoing value, Felix Mobile's unlimited plan at $40/month (or $20 for the first 3 months) or Amaysim's $30 plan with 32 GB are better choices for most users.
Can I switch providers and keep my number?
Yes. Number porting (keeping your existing mobile number) is available with all Australian providers including MVNOs. You initiate the transfer through your new provider — it usually completes within a few hours.
Are MVNO plans safe and reliable?
Yes. MVNOs are regulated by ACMA and ACCC and use the same infrastructure as the major carriers. Your calls and data run on the same towers — the only difference is the billing and support layer.
How do I switch to a cheaper plan?
Choose a plan on Switcheroo, order the SIM or activate an eSIM, and transfer your number. The whole process typically takes under 30 minutes and you can do it entirely online. Your old service will cancel automatically once the port completes.
