You are landing in Sydney or Melbourne after a 14-hour flight. You need data for the Uber to your accommodation, a WhatsApp call home, and a Google Maps search for the nearest supermarket. You do not want to queue at a kiosk in the arrivals hall.
An Australia eSIM from Slashtel sorts this before you leave. You scan a QR code at home, connect to an Australian network when you land, and pay from $2.79. No contract, no Australian address, no bank account needed.
UK working holiday makers. You are 18-30, on a 417 visa, and heading to Sydney, Brisbane, or Perth for a year. You will work in hospitality or construction, share a flat in Bondi or Fitzroy, and travel up the east coast on your days off. You need a phone number that works for job hunting and a data plan that does not punish you for using Google Maps on the bus.
Indian students and professionals. You are arriving for a February or July intake at a university in Sydney, Melbourne, or Adelaide. You need data from the moment you land, before you have a local bank account or a permanent address. You also want to keep your Indian SIM active for bank OTPs. Our eSIM runs alongside your physical SIM, so you get Australian data and keep receiving those verification codes.
Data needs vary. Here is a practical guide:
| Data | Duration | What it covers |
|---|---|---|
| 1GB | 3-5 days | Maps, WhatsApp text, light email. No video. |
| 3GB | 1 week | Maps, WhatsApp calls, occasional Instagram. |
| 5GB | 2 weeks | Maps, WhatsApp video, some Spotify streaming. |
| 10GB | 1 month | Daily use including YouTube and video calls. |
For a working holiday, start with the 10GB plan. You will use more than you expect, especially for job hunting, property viewings, and weekend trips. For a two-week holiday, 5GB is the safe middle ground.
Arrival airport data. Sydney and Melbourne airports have free Wi-Fi, but it is slow and requires registration. The eSIM connects within a minute of landing, so you can skip the airport Wi-Fi entirely. The data plan starts on first connection, so if you install but do not connect until you reach your accommodation, you do not lose days.
Keeping your home SIM alive. If you are from India, keep your Airtel, Jio, or Vi SIM active for bank OTPs and UPI alerts. Our eSIM is data-only, so your home SIM stays in the phone for SMS. If you are from the UK, you can keep your UK number on a pay-as-you-go plan for two-factor authentication from your bank. You do not need to cancel anything.
You need a stable Wi-Fi connection to install the eSIM. Scan the QR code from the confirmation email, add the data plan to your phone, and it is ready. The whole process takes about two minutes. If you get stuck, follow our installation guide for step-by-step instructions for iPhone and Android.
Once installed, the eSIM sits dormant until you switch it on in Australia. You can keep your home SIM active for calls and SMS, and use the eSIM for data. That is the whole setup.
Browse Australia data plans and pick the size that matches your trip. Prices start from $2.79 for 5GB. The QR code lands in your inbox within a minute, and you are ready to fly.

No. Your phone needs to be unlocked to use any eSIM, including ours. If you bought your phone outright from Apple or Samsung, it will be unlocked. If you got it on a contract from a major UK network, check with them first. Most will unlock it for free once your minimum term ends.
Yes, as long as you keep your Indian SIM active on a roaming plan or with sufficient balance. Your bank OTPs will come through on the home network's roaming service. You can install our Australia eSIM alongside your physical Indian SIM and switch data to the eSIM, keeping your Indian number active for SMS.
For a typical 2-week trip using Google Maps, WhatsApp, and occasional social media, 5GB is usually enough. If you plan to stream video or make frequent video calls, go for 10GB. You can always top up through the app if you run out.
Yes. Install and activate the eSIM while you still have Wi-Fi at home or at the airport before departure. The data plan starts when you connect to an Australian network. If you wait until you land, you will need to find free Wi-Fi at the airport to scan the QR code.
Yes. Our eSIM connects to a major Australian network, which covers all major cities and most regional areas. Coverage in the outback can be patchy regardless of provider, so plan for that if you are driving long distances.
Yes. You can enable personal hotspot on your phone and share the data connection with your laptop or tablet. Useful for working remotely or checking in for flights. Just keep an eye on your data usage, as hotspot use tends to consume more.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Australia is $8.99 on Optus and Telstra. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
From $2.79 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $4.29 (3GB), one month from $4.69 (3GB).
$0.64 per GB on the 50GB plan (30 days, $31.89). Bigger plans usually cost less per GB, so buy the size you expect to use.
Optus and Telstra, with speeds up to 5G where available. The eSIM picks the strongest network automatically.
No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
Validity starts when the eSIM first connects to a network in Australia, not when you buy it, so you can buy and install it before you travel.
After payment Slashtel emails a QR code within a minute. Scan it in your phone settings while on Wi-Fi at home, then switch on data roaming for the eSIM when you land.
Your phone must support eSIM and be carrier-unlocked. Dial *#06#: if an EID appears, the phone supports eSIM.
Yes. Hotspot and tethering are allowed on Slashtel eSIMs.
