One of the first things every new immigrant or international student needs is an Australian mobile number. You'll need it for bank accounts, Medicare, flat-hunting, and job applications. But before you walk into the nearest Telstra or Optus store, there are a few things you should know.
1. Identification Requirements
Under Australian law, every SIM card must be registered. As a new arrival, you can use your **Foreign Passport** and your **Visa** (Digital or Physical) to activate a SIM. You do NOT need an Australian Driver's License or a local credit history for **Prepaid** plans.
Avoid the "Contract Trap"
Most major carriers will try to sell you a 12 or 24-month contract. **Don't do it.** As a newcomer, you won't have the "Credit Score" required for these, and the rejection can hurt your future financial applications. Stick to **SIM-Only Prepaid** or **No-Contract Monthly** plans.
2. Best Plans for International Calls
If you need to call home frequently, you should look for MVNOs that include "Unlimited International Minutes" to specific countries.
- Amaysim: Excellent for students. Very cheap plans and often includes 28+ countries for free.
- Lebara: The classic choice for expats. Great coverage in metro areas and very high international minute allocations.
- Boost Mobile: If you are moving to a regional or rural campus, Boost is the only budget provider that uses the **Full Telstra Network**.
3. Will your foreign phone work in AU?
Most modern smartphones are global, but some older models from Asia or the US might lack certain Australian 4G/5G frequency bands. More importantly, **Australia has shut down its 3G networks.** If your phone is "3G only," it will not work at all here.
If your phone is "Carrier Locked" to your home country (common in the USA and UK), you'll need to get it unlocked before an Australian SIM will work. Check our phone unlocking guides here.
Tech Tip: Local Charging
Australia uses **Type I power plugs** (230V). Don't use cheap, uncertified travel adapters that can overheat and fry your battery. We recommend using a certified **RepairRange SafeCharge GaN block** with a local cable for safe, fast charging. [Browse local accessories].
Summary Checklist for Day 1:
- Have your passport and visa ready.
- Buy a Prepaid SIM card from a grocery store (Woolworths/Coles) or airport kiosk.
- Download the provider's app to activate using your passport.
- Test your signal. If it's weak, your phone's antenna might need a technical checkup at Mayfield Phone Repair.
