We sell the SIM Shop option, so this is a retailer’s comparison of published offers, rather than an independent network test. The useful differences are the selected price, how you manage the service and what the refund wording means before you install.
The Japan comparison, in one currency
| Selected Japan offer | Total data | Active period | Displayed AUD price |
|---|---|---|---|
| The SIM Shop | 10GB | 30 days | A$19.95 |
| Ubigi | 10GB | 30 days | A$29.00 |
Our selected offer starts at first supported-network connection and has 60 days from purchase to start. Ubigi’s Japan product page describes Smartstart activation on arrival, data sharing and a reusable profile, with app recharges available without Wi-Fi or data credits. Those are practical account features, particularly if you expect to buy another plan during the trip.
That page lists KDDI, NTT Docomo and Softbank. Their inclusion is useful information, but it doesn’t establish better reception on a particular mountain or railway than another offer. We haven’t field-tested the two services side by side, and corporate ownership isn’t evidence that one will cover your exact stop better.
A useful unlimited example, with a specific threshold
Ubigi’s seven-day Europe unlimited offer gives you 25GB at full speed across the whole plan, then 2Mbps. That isn’t another 25GB each morning, or the rule for every Ubigi plan.
For a stated seven-day pattern of 1GB on six days and 4GB on one day, the total is 10GB, below that 25GB threshold. A 1GB-per-day high-speed service would handle the 4GB day differently, even though both might cover the week’s total. Compare the usage pattern and the exact reset or fair-use rule, not just the word unlimited.
Our current Europe range has its own 32-country list, including the UK and Switzerland but excluding Morocco and Andorra. Compare the full itinerary before taking either Europe name as the answer.
Ubigi's refund pages still use different tests
The terms page ties a preloaded website-plan refund to not having scanned the emailed QR, whereas the refund help page uses whether data has been used. They also differ on carrier-locked devices: the terms exclude that refund, while help says one may be possible.
Those are different outcomes for a person who installed but hasn’t used the plan. If cancellation remains possible, leaving the code unscanned avoids changing the order while you seek a written answer from Ubigi. Its help route requests the payment receipt within 14 business days of purchase or the technical issue and describes an eligible refund to the original payment method within ten business days.
Our policy instead gives a standard 30-day discretionary unused, uninstalled and unactivated window, with eligible automatic requests checked through My Account > Refunds. Installed or used orders need assessment; neither retailer’s discretionary wording removes applicable consumer rights.
Which difference matters for your trip?
For the selected Japan allowance and duration, the A$9.05 saving is a concrete reason to consider us. If a reusable profile and in-app recharges are more valuable to you, Ubigi’s documented features deserve a look, with its refund wording settled before any cancellation-sensitive installation.
Check the exact phone, sales region and unlock status before either purchase. For our eSIM, save the email before flying and install after landing on working, steady Wi-Fi, following that order’s settings. For Ubigi, use its own instructions rather than borrowing ours.
These selected prices and pages were reviewed on 31 October 2026. They don’t establish the cheapest provider for every country, a support-response ranking or a promise of reception at your accommodation.
