Airalo vs The SIM Shop: fixed data, unlimited and sharing

Let the Japan phone budget and busiest sharing day lead the Airalo comparison, with fixed and unlimited terms kept beside their own offers.

Black Friday 2026, coming 20 to 30 November: We’re announcing up to 59% off selected eSIM plans. The sale hasn’t started yet. See the upcoming prices, previous prices and discounts, and check when your chosen plan needs to be started.

Disclosure: We’re The SIM Shop, an Australian travel eSIM retailer. We compete with the providers discussed here.

Choose fixed or unlimited before comparing prices

Airalo offers both fixed-data and unlimited options. A page opening on Unlimited doesn’t mean Standard fixed data is unavailable. Choose the allowance model first, then the country and duration you need.

For a Japan data budget

Our Japan 10GB/30-day fixed offer is A$19.95. For a planned 8GB total across 14 days, it fits with 2GB spare. Match that need against Airalo’s selected fixed-data offer and final checkout currency; don’t compare our 10GB total with its cheapest 1GB headline.

If the phone needs a planned 4GB a day for seven days, that’s 28GB. The 10GB offer doesn’t fit, no matter how attractive its price is. That’s when a larger pool or a suitable unlimited offer belongs in the comparison.

Airalo’s unlimited fair-use rule

Airalo’s default unlimited rule gives you 3GB at faster speeds in each 24-hour period from activation, then 1Mbps until that period resets. An individual package can state a different amount, so use its details. The default reset isn’t necessarily local midnight. Personal hotspot is allowed without a separate sharing or device-count limit under that policy, but shared use can still reach the faster-data threshold.

Permission to share doesn’t mean unlimited high-speed sharing. A planned 4GB combined phone-and-laptop day exceeds the default 3GB high-speed threshold. Match the selected package, not just the word unlimited.

Our Japan sharing examples differ too

Our seven-day Japan 10Mbps unlimited offer is A$24.95 with 6GB of hotspot across the whole plan. The seven-day full-speed offer is A$34.95 with no separate hotspot allowance. Longer local KDDI offers have different sharing, rolling fair-use and Japan-calendar-day terms. Keep those conditions with their exact family.

Rewards shouldn’t hide the purchase price

Airalo’s programme starts at 5% Airmoney and has higher tiers. New customers shouldn’t assume they earn 10%. SIM Shop Credit earns 5% on eligible spend with caps, a pending period and 12-month expiry. Both are future-use benefits rather than cash already deducted from today’s order.

Which would we choose?

For a workable data budget, compare the suitable fixed offers. For heavier or uncertain use, compare the actual high-speed and reset rules, plus hotspot. Airalo’s broad app-based range can be convenient; our selected AUD offer and support route may suit another traveller. Neither company name answers the whole trip.
