Best Mobile Phone Plan for New Arrivals in Australia
Migratio Editorial · Last updated
TL;DR: Telstra, Optus and Vodafone (TPG) are Australia's three mobile network operators; every other brand, including Aldi Mobile, Boost and amaysim, runs on one of these three networks. Prepaid suits new arrivals because it needs no credit check or Australian bank account. Data inclusions and prices change often — check each provider's current plans before choosing rather than relying on a fixed price here.

You need a mobile phone the moment you arrive in Australia. This guide explains prepaid vs. postpaid, how the three underlying networks compare, and how to activate a number before or when you land. Specific plan prices and data inclusions change frequently, so this guide focuses on what stays true regardless of the current pricing round — check each provider's own site for today's numbers.
Network Basics: Coverage Matters More Than You Think
Australia has three companies that operate their own mobile network infrastructure — Telstra, Optus, and Vodafone (owned by TPG Telecom). Every other mobile brand you'll see advertised, including Aldi Mobile, Boost Mobile, amaysim, Woolworths Mobile, and many others, is a Mobile Virtual Network Operator (MVNO): it resells capacity on one of these three physical networks rather than building its own towers.
Telstra has historically operated the largest network footprint by geographic area and is generally regarded as the strongest option outside major cities and in regional and remote areas. Optus and Vodafone/TPG operate smaller networks that are typically strongest in and around the major cities and larger regional centres. Coverage claims change as networks are built out, so check each carrier's own coverage map for your specific suburb, town, or travel route before choosing — don't rely on a general reputation alone.
An MVNO's coverage is identical to whichever network it resells: an MVNO on the Vodafone network gets Vodafone's coverage, not its own. Check which network an MVNO uses (this is usually stated on its website) before assuming it will work where you're moving.
Prepaid vs. Postpaid: Which Suits New Arrivals?
Prepaid
You pay upfront for a plan, most commonly running for 28 or 30 days. No contract, no credit check.
Best for new arrivals because:
- No Australian credit history is required.
- Flexible — switch plans or carriers any time a plan expires.
- No surprise bills.
- Easy to test which carrier actually works well where you live before committing further.
How it works:
- Buy a plan bundling data, calls and texts for a set period (commonly 28 or 30 days).
- The plan expires at the end of that period. You recharge (renew) or switch.
- Whether unused data carries over to the next period depends on the specific plan — check before assuming either way.
Best for: most new arrivals during their first few months, before they have an Australian bank account, address history and credit file.
Postpaid
You're billed monthly in arrears for calls, texts, and data. Providers typically run a credit check and require payment from an Australian bank account or card.
How it works:
- Sign up to a plan, commonly billed monthly with no fixed lock-in period on many current plans (some plans still bundle a handset over 24–36 months, which does lock you in).
- Pay the monthly bill from an Australian bank account or card.
- Postpaid plans generally include larger data allowances for a similar price to prepaid, since the provider is not carrying prepayment risk.
Best for: migrants who plan to stay long-term and have (or can quickly get) an Australian bank account and a stable address.
A postpaid application without an Australian credit history may still be accepted, be asked for a security deposit, or be declined, depending on the provider's own credit policy — this varies by provider and isn't something you can assume either way in advance.
Telstra, Optus and Vodafone: What Actually Differs
Because Telstra, Optus and Vodafone each operate their own network, the practical differences between them are: coverage in the specific areas you'll be in, plan pricing and data inclusions (which change regularly and are set independently by each company), and customer service. Mobile data inclusions in Australia have increased substantially over time at similar price points as the networks have rolled out 5G, so any plan price or GB figure quoted anywhere — including in older versions of this guide — should be checked against the provider's current plans page rather than trusted as current.
As a general pattern: Telstra has typically positioned itself as the premium, widest-coverage option and priced accordingly; Optus and Vodafone have typically competed more on price and data inclusions. This is a general market pattern, not a guarantee for any specific plan at any specific time — compare the current plans and prices on each provider's own website for the data allowance you actually need.
MVNOs: Budget Options on the Same Networks
Because MVNOs resell capacity on the Telstra, Optus or Vodafone network, an MVNO plan on, say, the Vodafone network will have the same coverage as a Vodafone-branded plan in the same area — the difference is price, inclusions, customer service model, and any retailer-specific perks (for example, Woolworths Mobile plans can earn Woolworths Rewards points).
Aldi Mobile and Boost Mobile are two of the better-known MVNOs and both publish current plans and network information on their own sites — check which host network each MVNO uses before choosing, since this determines the coverage you'll actually get, not the brand name. As with the major carriers, treat any specific price or data figure as a snapshot that needs checking against the provider's current plans page, since MVNO data inclusions have also increased substantially at similar price points in recent years.
How Much Data Do You Actually Need?
As a rough starting point for a new arrival:
- Light user (mostly on Wi-Fi, occasional calls and messaging): a smaller data allowance is usually enough.
- Average user (social media, maps and navigation, streaming music, email): a mid-tier data allowance covers most day-to-day use.
- Heavy user (video streaming, frequent video calls, heavy navigation use): choose a plan towards the top of a provider's current range.
During your first few months — job searching via apps, video calls home, and navigation while you find housing and get oriented — you're likely to use more data than usual, so it can be worth choosing a plan with more headroom than you expect to need long-term, then adjusting once you know your actual usage. Current data inclusions per dollar vary a lot between providers and change often, so compare what each provider is currently offering for the data tier you need rather than budgeting to a fixed price.
How to Activate Your Mobile in Australia
Option 1: Buy at the Airport
Pros:
- Activates immediately.
- English-speaking staff on hand to help.
Cons:
- Limited plan options compared with the provider's full range online.
- Airport pricing and inclusions can differ from the standard online range.
- Queues can be long after a flight lands.
How:
- Exit customs and baggage claim.
- Find a telco stand — Telstra, Optus and Vodafone typically have stands or kiosks in major international terminals.
- Buy a prepaid plan.
- Get a physical SIM installed in your phone, or activate an eSIM if your phone supports it.
- Receive your Australian phone number.
Option 2: Buy Online Before Arrival (eSIM)
Pros:
- Can be set up before you fly so data is ready when you land.
- Avoids airport queues.
Cons:
- Requires an eSIM-capable phone.
- Slightly harder to troubleshoot remotely if something doesn't work.
How:
- Check your phone supports eSIM (most recent iPhone and Samsung models do, among others).
- Visit the provider's website and choose a plan with eSIM activation.
- Receive an activation QR code by email.
- Scan the QR code on your phone before leaving home, or once you land.
- Activate the eSIM when you're in Australia (some providers require you to be in the country to activate; check the specific provider's instructions).
See Best eSIM for Australia Arrival for more detail on this option.
Option 3: Buy In-Store After Arrival
Pros:
- Staff can answer questions in person.
- You can ask about coverage in your specific area before choosing.
Cons:
- No phone service until you get to a store.
- Requires travelling to a retail store.
How:
- Get to a telco store — a Telstra, Optus or Vodafone store, or a retailer selling an MVNO SIM (for example, Woolworths for Woolworths Mobile).
- Buy a prepaid SIM and plan.
- Staff activate your number.
- Test coverage in the suburb you're staying in.
Common Mistakes
Assuming the cheapest advertised plan is automatically the best deal. Compare the actual network (Telstra, Optus or Vodafone) an MVNO uses, not just the headline price, since coverage depends entirely on the host network.
Not checking coverage for your specific area. Visit each network's own coverage map and search your actual suburb or town — advertised population-coverage figures are national averages and don't tell you what happens on your street.
Signing a long postpaid contract immediately on arrival, before you know whether the network suits where you'll be living and working, and before you have an Australian credit history to qualify easily.
Not considering an eSIM before arrival, when your phone supports it — this can mean having mobile data working from the moment you land instead of queuing at the airport.
Choosing on price alone without checking that the underlying network actually covers where you live and work — a cheap MVNO plan on a network with weak coverage in your area isn't good value regardless of the price.
Forgetting to test the network at your actual accommodation. Signal strength varies a lot by building and location — test speed and reliability where you live before committing to a longer postpaid contract.
Next Steps
- Check your phone's compatibility — does it support eSIM, or do you need a physical SIM?
- Decide roughly where you'll be living (major city vs regional) and check each network's coverage map for that area.
- Compare current plans and prices directly on the Telstra, Optus, Vodafone and relevant MVNO websites for the data allowance you need — don't rely on remembered or historical pricing.
- Choose prepaid for your first few months unless you're confident about a long-term postpaid commitment.
- Buy either an eSIM before you arrive or a SIM at the airport or in-store.
- Test your data speed and coverage at home and at work in your first week. If it's poor, you can switch — prepaid makes this easy.

Frequently asked questions
Do I need an Australian address or bank account to get a prepaid SIM?
No. Prepaid SIMs generally don't require an Australian bank account, address, or credit check. Providers are required to verify your identity (such as with your passport) before activating a prepaid SIM, regardless of your visa or residency status. Postpaid plans, by contrast, generally do require a credit check and an Australian bank account or card for billing.
Will my phone from home work in Australia?
Most modern phones work on Australian networks, but check that your phone is unlocked (not locked to your home carrier) and supports the frequency bands used in Australia. If your phone is more than a few years old or was bought outright from a carrier overseas, check its compatibility and unlock status before you rely on it.
What's the difference between an MVNO and a network operator?
Telstra, Optus and Vodafone (TPG) each build and operate their own physical mobile network. A Mobile Virtual Network Operator (MVNO) — such as Aldi Mobile, Boost Mobile, amaysim or Woolworths Mobile — doesn't own network infrastructure; it buys wholesale access to one of the three networks and resells it, usually at a lower price. An MVNO's coverage is identical to whichever network it resells, not better or worse.
Can I keep my overseas phone number after moving to Australia?
You can't transfer a foreign number onto an Australian SIM, but many people keep their overseas SIM active (or use an eSIM profile) for receiving calls or verification codes on their old number, while using a separate Australian SIM or eSIM for day-to-day use in Australia. Check your home provider's international roaming or account-retention options before you leave.
How do I check which network actually covers where I'll be living?
Use each network's own coverage map tool (Telstra, Optus and Vodafone/TPG each publish one) and search your specific suburb or town rather than relying on a national coverage percentage, which is an average across the whole country and doesn't tell you what signal you'll actually get at a specific address.
