Use prepaid data on the phone you already carry. This is how PikoeSIM compares with a rental router, home-carrier roaming and a physical SIM.

Frequently asked questions.
Answers to common setup and buying questions.
Which data plan should I buy for my travel dates?
The 100 MB and 500 MB options suit only light messaging and pulling up a booking. For a week of maps and browsing, weigh 3 GB for 7 days at €2.27 against 5 GB for 7 days at €3.68. On a longer stay, 10 GB for 30 days at €7.19 or 50 GB for 180 days at €35.30 leaves more room, but size the allowance to your heaviest days rather than the trip length alone. The lowest price is not automatically the best price for a fortnight; recommendations should follow your actual data habits.
Which mobile network and speeds will I get?
Listed networks: Optus Australia. Connects to 4G/5G where the network offers it. Speeds and signal vary with your phone, location and network conditions.
How do I check whether my phone can use this eSIM?
Confirm your exact model supports eSIM and is network unlocked. On an iPhone, look for "No SIM restrictions" under Settings > General > About. On a Pixel, the path is Settings > Network & internet > SIMs > Add SIM. iOS and Android steps differ, and regional versions can vary, so check the compatibility guide for your manufacturer.
When should I install the eSIM and start using it?
Install over reliable Wi-Fi and keep the supplied instructions saved offline. Follow the activation steps for your purchase; the exact start of validity depends on those plan instructions and is not confirmed in these listings. There is no instant installation guarantee, and if your order includes a QR code, scan it only as the instructions direct. On arrival, select the travel line for mobile data.
Will I get a local phone number for calls and SMS?
This is a data-only plan, so there is no local phone number, standard calls or SMS. Bank and verification codes sent to your regular number still depend on that SIM, your carrier and the sender. Check your home carrier's charges before you leave the regular line switched on.
Can I use my eSIM as a hotspot for other devices?
The listed networks support hotspot. Any device you connect draws from the same data allowance. Every connected device draws from the same allowance, and tethering works the same way. The data hotspot is included on the listed network. Pause system updates and photo backups while you are on a small plan.
Does my data reset each day or roll over?
No. The allowance shown is the total for the whole validity period, not a daily amount. There is no 1 day option, so even a one day stop means a 7-day plan. A trip of 14 days needs the 15-day option, and 2 weeks is not the same as 30 days. A 30-day plan runs close to one month but does not line up with a calendar month, and it is still a fixed total, not unlimited data.
Does this plan work outside Australia?
These offers include Australia only. For an onward stop, check the explicit country list on any separate plan. The operator's brand does not extend your included territory.
What should I check if mobile data won't connect?
Confirm you are in the included country, the travel line is enabled and selected for mobile data, and the plan still has data and validity left. Apply the supplied roaming and APN settings to that line, then try airplane mode or a restart. Keep the profile installed and note your device model, location and order reference when asking for help.
How do I avoid roaming charges on my home SIM?
Keep data roaming off on your regular SIM and turn off automatic mobile-data switching. Any roaming setting the travel eSIM needs applies only to that line. Calls and SMS on your home line can still run up carrier charges.
Can I add more data or get a refund later?
Before you buy online, check the purchase terms and available order options, and do not rely on a top up or profile reuse. Buying a second plan does not automatically extend the first, and these are one-off plans rather than a monthly subscription. The label "no contract" is a search term, not a promise in the terms, so read the purchase conditions. For help or a refund request, keep your order reference and setup details to hand.
Using your eSIM in Australia
An Australia eSIM that fits the way you travel
A tourist on a family holiday uses mobile data differently from someone on a solo vacation. The listed plan features a fixed total, so an airport train in Sydney, a coach into Melbourne and a long outback drive each need different preparation. Keep addresses and tickets on your phone, and store offline copies for stretches without signal.
Size the allowance to how you actually use the internet, not to the number of days on your ticket. WhatsApp messages and map lookups burn little data, while YouTube and photo uploads chew through it quickly. These are prepaid data plans with a fixed total, and only the allowance and validity change; pricing appears in EUR per plan. The cheapest listed option, 100 MB for 7 days, is affordable only if your use stays to occasional messages and pulling up a booking. For a week of maps and browsing, weigh the 3 GB plan for 7 days at €2.27 against 5 GB for 7 days at €3.68; the smaller one is not automatically the best value if you stream video most evenings. On a longer stay, 10 GB for 30 days at €7.19 or 50 GB for 180 days at €35.30 leaves more headroom, but match the total to uploads and hotspot sharing.
City arrivals and long distances
The listed operator is Optus Australia, with 4G/LTE and 5G where available. Network quality and service thin out across a country this size, and a longer validity window does not add reception on remote roads or at sea, so we would not promise best coverage in the outback. Download maps before you leave a town and arrange separate communications for remote travel.
Your next stop.Sydney Harbour, Australia
Sydney: pick the rail station that matches your terminal.
Sydney Airport has an International station and a Domestic station serving T2 and T3. Open your flight details before you fix a pickup or train, because the terminal changes where you meet someone or catch a connecting flight.
Airport Link runs between the airport and the city about every 10 minutes. Use a transport planner to check your destination station and the walk to your hotel, then save that last leg. Mobile internet helps you find the train, but the fare is a separate purchase.
For a harbour day, pin your accommodation before you head to the Opera House. If you picked one of the small MB plans, leave full photo backups for Wi-Fi.
Save before you goSave your flight terminal, hotel entrance, rail route and the airline's transfer instructions before you lose signal.
Melbourne: treat Southern Cross as a transfer point, not the finish line.
The SkyBus Melbourne City Express runs between Melbourne Airport and Southern Cross Station. The airport lists stops outside Terminals 1, 3 and 4, so check the stop for your arrival terminal before you walk out.
Southern Cross may be only the first leg of your journey. Pull up your accommodation address and check the onward tram, train or walk while you still have a connection. Keep the ticket and booking reference somewhere other than the email that carried them.
If a driver is collecting you, follow the airport's current pickup directions. Forecourt layouts can shift, and a message that only says "outside arrivals" matters less than an agreed pickup zone.
Save before you goYour bus ticket, onward directions from Southern Cross and the pickup zone if a driver is meeting you.
