We’re The SIM Shop and sell one of the alternatives. If your next trip needs something different from Nomad, it helps to name that change first: more room on one busy day, a known AUD purchase price, or a laptop connection you can rely on. Those lead to different choices below.
For a fixed Japan data budget in AUD
For ten days in Japan, say you allow 0.7GB daily plus 1GB spare. That's 8GB, so a 10GB total plan leaves 2GB.
Our selected Japan 10GB/30-day offer is A$19.95. SimCorner's matched fixed amount and duration is A$25, and Airalo's Australian fixed-data selection shows A$26.50. These are current displayed AUD quotes for that data-only example; they don't include ordinary calls or establish the best deal in another country.
Nomad's storefront localises currencies and promotions. Compare its final quote for the same amount and duration rather than treating an old USD number as today's AUD price. Future points aren't a reduction in this trip's cash charge unless you can actually redeem them at this purchase.
For a busy day that needs more high-speed data
Airalo's general unlimited policy states a default 3GB per twenty-four hours from activation, then 1Mbps, with exceptions on individual packages. Saily's regular Japan unlimited offer states 5GB daily, then 1Mbps, resetting at local midnight.
An assumed 4GB upload in one day, before any other use, exceeds Airalo's default allowance but fits inside Saily's stated Japan daily 5GB. That makes the selected Saily product relevant to that particular requirement. A 7GB day would exceed both stated daily amounts, so consider a suitable fixed total pool or Wi-Fi for that upload instead.
Ubigi also has whole-plan and selected daily unlimited products. Its daily explanation includes 5GB then 2Mbps with twenty-four-hour resets from activation. Choose the actual country package; a seven-day duration alone doesn't identify the high-speed threshold.
For essential laptop sharing
The phone-data allowance and hotspot conditions need to meet the workload together. Our selected seven-day Japan full-speed unlimited offer is A$34.95 with no separate hotspot allowance, subject to device and network performance. The A$24.95 seven-day 10Mbps option instead has 6GB total hotspot.
If you need an assumed 10GB of sharing across the week, the latter is short by 4GB. Holafly Japan's 1GB daily sharing cap permits at most 7GB across seven days and is also insufficient. Don't change providers to a plan that solves phone data but fails the laptop requirement.
For uncertain travel dates
Holafly's unactivated direct-purchase refund route has a six-month request window, subject to its conditions. Nomad's published plan refund policy uses a thirty-day purchase window and separates unused orders, verified service issues and product-specific exceptions such as unlimited, DTAC and UK voice plans.
A longer request window doesn't pause a start deadline. Our selected Japan fixed and short unlimited examples have sixty days to start; Nomad's current Japan page also describes an automatic start after its sixty-day activation window. Buy at the right time for your dates rather than treating a cancellation headline as indefinite storage.
For a phone without eSIM
SimCorner and Travelkon sell physical SIM products as well as eSIMs. A physical option can suit an unlocked handset without eSIM support. Include delivery time and that product's own allowance in the comparison. Another eSIM retailer cannot make an unsupported phone compatible.
If a Nomad order isn't working, leave its profile installed and contact Nomad with the order, country, model/software, exact error and settings tried before buying a replacement. For our new purchase, save the email before flying and install after landing on working airport Wi-Fi after sign-in, or hotel Wi-Fi. Keep Australian-line data roaming off and automatic data switching disabled.
