Frequently Asked Questions
Can tourists buy a SIM card in Sydney?
Yes, but Australian prepaid SIMs only work after an ID check: the rules require the carrier to verify your identity before the service is activated, and visitors usually show their passport in a carrier store. A travel eSIM can be bought online and installed before you fly, and connects to Telstra, Optus or Vodafone when you land at Sydney Airport.

Is it worth getting an eSIM for Sydney?
For most travellers, yes, if your phone supports eSIM. Sydney plans start at $3.49 for 2 GB, and the longest lasts 365 days, which suits long stays and repeat visits. If your home plan already covers Sydney at no extra cost, you may not need one.

How much data do I need for a week in Sydney?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB

The cheapest Sydney plan with at least 5 GB for a week or longer is 5 GB for 30 days at $4.99.
Is there an unlimited data eSIM for Sydney?
Yes. Unlimited data plans for Sydney start at $10.99. Many unlimited plans slow down after a daily high-speed allowance, so check the fair-use terms on the plan page before you buy.
Do Sydney eSIMs support 5G and hotspot?
5G is available on 27 plans for Sydney, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Sydney eSIM come with a phone number?
Most travel eSIMs, including most Sydney plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Sydney eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.

Mentions SydneyPurchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.
