We're The SIM Shop and sell one of the alternatives. The examples below use current selected Japan offers, not a claim that one shop is cheapest everywhere.
For a lower fixed-data price
These are 10GB total over 30 days in Japan, checked on 30 October 2026:
| Provider | Displayed price | Currency |
|---|---|---|
| The SIM Shop | A$19.95 | AUD |
| SimCorner | A$25 | AUD |
| Airalo | A$26.50 | AUD in the Australian fixed-data selection |
| Saily | US$17.99 | USD |
| Ubigi | US$16.50 | USD |
Our selected fixed offer is A$6.55 below the Airalo offer and A$5.05 below SimCorner in this matched example. The USD figures aren't Australian-dollar prices, so they don't establish an AUD winner. Card conversion and any foreign-transaction fee can change the final charge.
Suppose your ten-day trip needs 0.7GB a day plus 1GB spare: 8GB altogether. A 10GB total plan leaves 2GB. Choose that allowance if those assumptions fit your own habits. You don't need unlimited phone data merely because your holiday is ten days long.
For a different hotspot arrangement
Airalo's general unlimited policy permits personal hotspot use without a stated device-count cap, alongside its applicable phone-data fair-use conditions. Leaving it for a plan labelled unlimited can reduce the sharing allowance.
For example, Holafly Japan lists 1GB of hotspot daily. Our seven-day Japan 10Mbps unlimited offer costs A$24.95 and has 6GB total hotspot. Neither meets a requirement to share 10GB over seven days. Our selected seven-day full-speed offer at A$34.95 has no separate hotspot allowance, making it a relevant option for that stated requirement, subject to network and phone performance.
Our fixed 10GB offer uses network- and device-dependent hotspot wording. If sharing is essential, don't treat the lower fixed price as proof of equivalent tethering support. Send us the exact offer and device before buying; choose confirmed suitable sharing terms if that cannot be established.
For a physical SIM
SimCorner sells physical SIMs as well as eSIMs. That is a practical alternative if the phone is unlocked but doesn't support eSIM. Compare the physical product's destination, allowance and delivery timing; the eSIM prices above aren't a postage-inclusive physical-SIM quote.
If the phone is carrier locked, changing retailers won't remove the lock. Ask the original carrier about unlocking first. Our compatibility checker separates model support from that carrier restriction.
For uncertain travel dates
Holafly's published refund policy gives an unactivated direct purchase a six-month request window, subject to its conditions. Airalo's withdrawal route ends at the earlier of fourteen days from purchase or activation; service-fault remedies are separate. Saily's one-off generally-unused routes use a thirty-day purchase window and additional activation/usage conditions.
Those are reasons to consider a provider, not promises that every order can be cancelled. Buying closer to a confirmed trip can avoid paying outside a start window. Our selected Japan 10GB plan has 60 days to start, separately from its 30-day running validity.
If your current Airalo order isn't working
Try the Airalo recovery steps before buying a replacement. Keep its profile installed and ask Airalo to confirm the plan's network, APN and activation status. A second purchase is not an assurance that the first seller will reimburse it.
For a new purchase, use the trip planner with your destination, dates, travel style and sharing needs. It estimates data and shows an available fit when possible; it doesn't compare competitor prices. For the assumed 8GB example above, 10GB is the useful starting allowance.
Buy and save our email before flying. Install after landing on working airport Wi-Fi after its sign-in page, or use hotel Wi-Fi. Select travel data, keep Australian-line data roaming off and disable automatic switching.
