Yomojo vs Felix Mobile vs Amaysim: Which One Should You Choose?
This guide is designed for Australians seeking a clear, up-to-date, and no-nonsense comparison of Yomojo, Felix Mobile, and Amaysim prepaid SIM only plans, helping you understand what each provider currently offers so you can choose the option that best fits your mobile usage and budget.
What Is a Prepaid SIM Only Mobile Plan?
A prepaid SIM only mobile plan is a mobile service you pay for upfront that provides a SIM card without a handset included and gives you a set allowance of calls, texts, and data until the plan expires.
It does not include a phone, so you use your own handset and insert the SIM or eSIM to activate the service. These plans operate on a pay-as-you-go or prepaid renewal system, where you top up credit or recharge every 28 or 30 days. This structure is used by providers such as Yomojo, which offers prepaid no-lock-in options on the Optus network, Amaysim, which provides 28-day and long-expiry prepaid SIM only plans, and Felix Mobile, which runs on a prepaid monthly renewal model with no lock-in contract.
Because there is no contract, no handset repayment, and no long-term commitment, prepaid SIM only plans suits users who want flexibility, predictable spending, and the freedom to switch providers whenever a better deal appears.
Who Is This Comparison For (And Who It's Not)
This guide helps you navigate Yomojo prepaid mobile plans, compare Felix Mobile vs Amaysim, and identify the best value prepaid SIM through a clear, user‑friendly prepaid mobile plans comparison. It is intended for Australians looking for flexible, straightforward SIM only options rather than phone bundles or long‑term contracts.
Network Coverage Comparison in Australia
When choosing between SIM only prepaid providers, it helps to know which mobile network they operate on. Coverage varies by region, so the best option depends on where you live, work, or travel. Below is a factual, neutral overview of the network each provider uses.
Yomojo Coverage
Yomojo operates on the Optus mobile network, using the Optus 4G Plus infrastructure across Australia. This provides coverage throughout all capital cities and many regional towns, with Optus reporting population coverage of around 98.5%, though actual reach varies depending on location and local tower availability.
You can check coverage for your specific suburb or postcode using Yomojo's official coverage checker.
Felix Mobile Coverage
Felix Mobile operates on the Vodafone 4G and 5G network provided by Vodafone (part of TPG Telecom). Vodafone reports population coverage of around 98.4%, with signal availability in metropolitan centres and many regional areas. Coverage may be less consistent in remote locations due to tower distribution and local terrain.
Amaysim Coverage
Amaysim's prepaid SIM only plans use the Optus mobile network, including Optus 4G and, where available, Optus 5G coverage. This network provides broad reach across urban centres and many regional communities, with real‑world performance depending on local conditions such as terrain, building density, and device compatibility.
Prepaid Plan Flexibility & Data Management
When comparing how providers structure their SIM only prepaid plans, it helps to understand how each brand handles flexibility, data control and renewal options. Below is a clear, guide‑style overview of how Yomojo, Felix Mobile, and Amaysim manage their prepaid mobile plans.
How Yomojo's Plan Structure Works
Yomojo's prepaid system is designed for users who want flexibility and control over their data. The plans allow you to choose a data tier that suits your usage and adjust it at each renewal, helping you avoid paying for inclusions you do not need.
Yomojo offers several prepaid data tiers on the Optus 4G Plus network, giving you the freedom to select the allowance that best fits your needs. You can easily upgrade or downgrade through your Yomojo Dashboard or Yomojo App whenever your usage changes. This level of adjustability helps reduce wasted inclusions because you can tailor your data allowance.
Felix Mobile's Unlimited Model
Felix Mobile follows a simple, set-and-forget structure built around unlimited data with a fixed speed.
Felix Mobile offers a flat‑fee monthly plan that includes unlimited calls, texts, and unlimited mobile data at speeds of up to 40 Mbps, providing an uncomplicated option for users who prefer predictable billing. Because the plan comes with a fixed speed cap and cannot be customised for lighter or heavier data use, it gives users less control compared with modular data providers.
Amaysim's Traditional Prepaid Bundles
Amaysim uses a more traditional prepaid bundle design with fixed data amounts and defined expiry cycles, giving users a predictable structure.
Their prepaid plans include set data inclusions, unlimited standard calls and texts, and options for 28‑day or long‑expiry periods, which makes budgeting easier for those who prefer stable plan costs. Because the plans are pre‑set, they offer less month‑to‑month adjustability, meaning users choose fixed bundles rather than building or modifying their own data allowance.

To help you compare SIM only prepaid plans in Australia, including the prepaid mobile plan options from Yomojo, Felix Mobile, and Amaysim, this guide provides a clear and easy‑to‑follow summary showing how each provider differs in plan flexibility, data management, contract terms, and customer support. The comparison table below brings these details together in a simple format, so you can quickly understand which service aligns best with your mobile needs and usage habits.
Customer Service & Real User Feedback
Looking beyond plan features, how a provider supports you when things go awry (or when you simply need help) is an important part of choosing SIM only prepaid plans in Australia, especially for prepaid users who may not have a retailer or handset included with their plan.
Yomojo Customer Service Experience
According to publicly available customer reviews on ProductReview.com.au, Yomojo earns a strong customer satisfaction score, with its rating recently rising to 4.7 out of 5 following improvements to customer service systems and staffing.

This level of responsiveness is particularly valuable for prepaid users, as they manage plan recharges, number transfers, billing questions, network coverage, and troubleshooting independently.

A strong support system can make the onboarding and ongoing experience much smoother, especially for those switching providers or managing multiple services.
