We're The SIM Shop, a competing retailer. The useful comparison here is between the two selected services, with our own offer kept to one optional price reference.
Work out whether ten gigabytes is the right amount
Suppose you budget 0.7GB per day for ten days, plus 1GB reserve. That's 8GB, leaving 2GB on a 10GB total plan. The two 10GB/30-day offers compared next suit those assumptions. A seven-day version wouldn't cover all ten days even if its allowance is identical.
A matched amount, with the currencies left visible
| Japan fixed plan | Display captured 30 October 2026 |
|---|---|
| Airalo, 10GB/30 days | A$26.50, Australian fixed-data selection |
| Nomad, 10GB/30 days | €14.28 sale, with €16.07 also displayed in the captured storefront |
Nomad displayed euros in this check, although its storefront supports localisation; that doesn’t mean an Australian buyer must pay euros or cannot choose AUD. To compare in Australian dollars, use the final quote for the same 10GB/30-day package and include any currency fee from your card. Airalo’s A$26.50 is an AUD benchmark here; the displayed 14.28 is in euros. Store credit and future rewards are separate from what you pay for this trip.
For an Australian-dollar comparison, use the final quote shown for the same 10GB/30-day package and any currency fee charged by your card. The concrete benchmark here is Airalo's A$26.50 quote, not the bare number 14.28. Store credit and future rewards are separate from the cash paid for this trip.
For reference, our Japan 10GB/30-day fixed offer is A$19.95. That doesn't settle the choice between every product from these providers; it gives you another matched data-only purchase to consider.
Daily unlimited needs its own conditions
Airalo's general unlimited policy states a default 3GB high-speed allowance per twenty-four hours from activation, then 1Mbps, with package-specific exceptions. Nomad sells different unlimited and day-plan arrangements; its own general explanations are not a single numeric rule for every current country package.
If you need an assumed 4GB upload in one day, Airalo's default threshold is exceeded. For Nomad, use the selected Japan package's Plan Details to establish its high-speed amount, reduced speed and reset before choosing it for that upload. If those details don't confirm the requirement, use a fixed total allowance or move the upload to Wi-Fi. Don't borrow a threshold from a different Nomad country or older day-plan page.
The same applies to hotspot: Airalo's general policy permits personal sharing, while the selected Nomad offer must establish its own terms. Neither a phone-data label nor an empty hotspot field proves unlimited laptop suitability.
Start dates and add-ons
Nomad's current Japan page states a 60-day activation window, after which the plan automatically activates. It also describes plan-specific add-ons, with their own activation behaviour. Don't buy far ahead and assume the plan can wait indefinitely.
Airalo's activation policy and available top-ups are shown for the selected package. Open My eSIMs → Details for its connection instructions and available options. A saved profile doesn't prove that a new allowance is active.
If either provider's current profile is working and meets the next trip's coverage and data requirements, retaining that setup can be useful. If the phone is locked or the exact regional model doesn't support eSIM, changing between these two won't remove the device restriction.
Refunds: unused plans and technical faults have different rules
Nomad publishes a thirty-day purchase window in its plan refund policy. It distinguishes uninstalled/unactivated plans, verified technical problems after use, removed single-use profiles and purchases with discount codes. It also expressly sends DTAC, UK voice and unlimited plans to their own product-specific refund rules. Use those rules rather than a blanket statement that all activated orders have the same remedy.
Under that policy, Nomad won’t refund a purchase made with a discount code after the eSIM is installed or the plan is activated.
Airalo's withdrawal route ends at the earlier of fourteen days from purchase or activation; technical problems have separate conditions. For either provider, keep the profile installed and send the receipt, exact plan, location, error and checks already tried. Report a fault during the trip while it can be investigated.
Rewards aren't the cash price
Nomad's points help gives a useful example: a US$12 purchase earns 50 points, redeemable as US$0.50. That's about 4.17% of that purchase, rather than a flat 5% return on every total. Redemption conditions and expiry still apply. Don't pay more for an allowance you won't use simply to earn future credit.
