A SIM-only plan could be the perfect solution if you already own a smartphone and want a cheaper, more flexible mobile plan. Unlike traditional mobile contracts that bundle a phone with a plan, SIM-only plans let you choose your own device while enjoying a cost-effective and customisable mobile service. 

With more Australians moving away from expensive long-term contracts, SIM-only plans are becoming the preferred choice for many mobile users. But what makes them so popular? In this guide, we will explore the key benefits of SIM-only plans, why they are a better alternative to traditional mobile contracts, and how Exetel’s SIM-only plans stand out from the competition. 

 

What is a SIM-Only Plan? 

A SIM-only plan is a mobile plan that provides you with a SIM card and mobile service, but not a handset. Unlike traditional mobile contracts that lock you into 24- or 36-month agreements with a phone repayment plan, SIM-only deals allow you to bring your own phone (BYO phone) and only pay for calls, texts, and data. 

SIM-only plans come in different formats: 

  • Prepaid SIM-only plans – You pay upfront for a set number of calls, texts, and data, which you can use for a specific period (e.g., 30 days). 

  • Postpaid SIM-only plans – You receive a bill at the end of each billing cycle, based on your usage and plan inclusions. 

Whichever type you choose, SIM-only plans offer more affordability and flexibility than traditional phone contracts. 

 

Why Choose a SIM-Only Plan? 

1. Significant Cost Savings 

One of the biggest reasons people switch to SIM-only plans is to save money. 

  • Traditional mobile contracts bundle the cost of a new handset into your monthly bill, making payments significantly higher and unnecessary if you already own a mobile phone. 

  • With a SIM-only plan, you only pay for the mobile service, reducing your monthly expenses. 

  • If you already own a phone or buy one outright, you can avoid additional phone repayments and lower your overall costs. 

A new smartphone on a 36-month contract can add up to an additional$250 per month to your bill. You could save hundreds—or even thousands—of dollars over time by choosing a SIM-only plan. 

 

2. More Flexibility and Control 

SIM-only plans give you complete control over your mobile service, allowing you to choose a wider range of plans that best suits your needs. 

  • Need more data? Pick a plan with a high data allowance. 

  • Want international call inclusions? Select a plan with overseas call minutes. 

  • Only need basic service? Choose an affordable low-data plan. 

With no lock-in contracts, you can change or upgrade your plan anytime, without worrying about cancellation fees. 

 

3. Freedom to Change Your Phone Anytime 

A major downside of traditional phone contracts is that they lock you into a single device for two or three years. If you want to upgrade to the latest phone, you either have to wait for your contract to end or pay the entire cost of the phone outright and sometimes other costly early termination fees. 

With a SIM-only plan, you are not tied to any specific device. 

  • You can upgrade to a new phone whenever you want, without restrictions. 

  • You can switch between different phones without changing your plan. 

  • You can keep using your current phone and avoid unnecessary upgrades. 

This makes SIM-only plans an ideal choice for tech enthusiasts who like to stay up to date with the latest devices. 

 

4. No Exit Fees or Cancellation Penalties 

Traditional mobile contracts lock you in for 24 or 36 months and may charge hefty exit fees if you decide to cancel early. 

With a SIM-only plan: 

  • There are no cancellation fees—you can leave anytime. 

  • You are not financially tied to a long-term commitment. 

  • You have the freedom to switch providers if you find a better deal. 

If you like having control over your expenses, a SIM-only plan is the perfect choice. 

 

5. No Credit Checks 

With a SIM-only plan, no credit check is required. Anyone can sign up, making it a more accessible option for a wide range of users. 

 

6. Customisable Plans to Suit Your Needs 

With traditional contracts, you are often stuck with the same plan for years, even if your usage habits change. 

With SIM-only plans, you can: 

  • Increase or decrease your data allowance as needed. 

  • Choose plans that include international calls and texts. 

  • Adjust your plan as your mobile usage changes. 

This flexibility ensures that you are only paying for what you actually need, not for extras you do not use.
