If you’re searching for the cheapest mobile plans in Australia, you’re not alone. With the cost of living rising, many Australians are looking for cheap SIM-only plans that still provide reliable network coverage.
Fortunately, Australia has a competitive mobile market with many budget mobile providers offering plans under $20 per month. These providers are known as MVNOs (Mobile Virtual Network Operators), meaning they operate on the networks of the major carriers such as Telstra, Optus, and Vodafone Australia.
In this guide, we compare the top 10 cheapest mobile plans in Australia and explain why Cmobile is one of the best options for Australians looking for a cheap mobile phone plan with Australian-based support.
Top 10 Cheapest Mobile Plans in Australia
When comparing cheap mobile plans in Australia, it’s important to understand that some providers advertise introductory promotional prices that increase after a few months. The table below shows both the promo price and the ongoing monthly price so you can see the true long-term cost.
| Rank | Provider | Promo Price | Ongoing Monthly Price | Data | Network |
|---|---|---|---|---|---|
| 1 | Cmobile | $10.90 | $10.90 | 500MB | Vodafone |
| 2 | Cmobile | $21.00 | $21.00 | 10GB | Telstra wholesale |
| 3 | Moose Mobile | $12.40 (6 months) | $24.80 | 30GB | Optus |
| 4 | TPG | $12.50 (6 months) | $25.00 | 25GB | Vodafone |
| 5 | iiNet | $12.50 (6 months) | $25.00 | 25GB | Vodafone |

| 10 | Lebara | $9.00 (1st month) | $19.90 | 10GB | Vodafone |
Pricing and promotions change regularly and may vary depending on current offers.
Why Showing Promo vs Ongoing Pricing Matters
Many cheap mobile plans in Australia advertise a low introductory price to attract new customers. However, the ongoing monthly price can be significantly higher once the promotion ends.
For example:
- Some plans start at $12–$19 per month
- But increase to $22–$25 per month after 6 months
This is why comparing ongoing pricing is the best way to understand the true cost of a mobile plan.
Unlike many competitors, Cmobile offers consistent pricing, meaning customers pay the same low monthly price without temporary promotional discounts.
These cheap SIM-only plans provide a simple way to reduce your monthly phone bill while still using reliable Australian mobile networks.
What Is an MVNO?
Most cheap mobile plans in Australia are offered by MVNOs.
A Mobile Virtual Network Operator (MVNO) is a mobile provider that rents network access from major carriers rather than operating its own mobile towers.
In Australia, most MVNOs operate on one of three major networks:
- Telstra (largest coverage)
- Optus
- Vodafone Australia
Because MVNOs don’t have the huge infrastructure costs of the big carriers, they can often offer much cheaper mobile phone plans.
Why Cmobile Is One of the Best Cheap Mobile Plans in Australia
When comparing cheap mobile providers in Australia, Cmobile stands out for several important reasons.
One of the cheapest monthly mobile plans in Australia
Cmobile offers a SIM-only mobile plan starting from just $10.90 per month, making it one of the lowest priced mobile plans available in Australia.
This type of low-cost mobile plan is ideal for:
- Kids’ first phones
- Seniors
- Light data users
- Backup or emergency phones
For customers who mainly make calls and send texts, this can be a much cheaper alternative to large data plans.
Australian-based customer support
One major difference between Cmobile and many other budget mobile providers is customer support.
While some cheap providers operate overseas call centres, Cmobile offers Australian-based customer service, which can make support easier and faster for local customers.
This is particularly valuable for:
- Seniors
- Families managing multiple services
- Small businesses
Choice of major Australian mobile networks
Another advantage of Cmobile is network flexibility.
Customers can choose plans running on:
- Vodafone network (C Red plans)
- Telstra wholesale network (C Blue plans)
This means users can select the cheap mobile plan with the best coverage for their area.
No lock-in mobile contracts
Like many modern SIM-only providers, Cmobile offers no lock-in contracts.
This means you can:
- Change plans anytime
- Cancel without early termination fees
- Switch providers if your needs change
For Australians who want flexible and cheap mobile plans, this is a major advantage.
Cheap Mobile Plans vs High-Data Plans
When searching for the cheapest mobile plans in Australia, it’s important to understand the difference between two common types of deals.
| Type of Plan | Example | Best For |
|---|---|---|
| Ultra-cheap low-data plans | Cmobile $10.90 | Light phone users |
| High-data promotional plans | Moose, TPG, SpinTel | Heavy data users |
Many comparison sites focus on large data plans, which means very low-cost plans sometimes get less attention — even though they may be the cheapest mobile plans available overall.
Who Should Choose a Cheap SIM-Only Mobile Plan?
Cheap mobile plans are ideal for Australians who don’t need large amounts of mobile data.
They are especially popular with:
- Families buying cheap mobile plans for kids
- Seniors looking for simple phone plans
- People who mostly use Wi-Fi at home
- Anyone wanting to reduce their monthly phone bill
For these users, paying $40–$70 per month for a mobile plan can be unnecessary.
