How to use the Ubigi promo code
Ubigi sells plans by destination and by length, topped up from its app without buying a new eSIM. The code goes in at payment time, on the order.
- 1Pick your destination and planVolume and duration are chosen before the basket, and that choice weighs most on the bill.
- 2Open the promo code fieldOn the payment screen, unfold the row reserved for the discount code.
- 3Apply and check the totalType ESIMRAT, submit, and watch the amount recompute before you pay.
The rat's advice: check the total BEFORE paying, never after. A settled order cannot be revisited, and support will not apply the discount afterwards.
The Ubigi promo code that works in September 2026
Only one code to remember: ESIMRAT, 10% off your first Ubigi order, created by the brand itself for eSIMrat and active on its partner program since August 28, 2026. It is entered at the time of payment, after creating your Ubigi account, for any destination.
There is no such thing as a 30% or 50% Ubigi code, regardless of what aggregator headlines claim. These pages pile up codes without dates or proof, relying on the fact that you will eventually end up using the only one that works. With an eSIM, margins do not allow for this kind of discount.
The Ubigi code active in September 2026
ESIMRATeSIMrat code, first order-10%ESIMRAT is the code created by Ubigi for eSIMrat. The 30% or 50% discount codes displayed by aggregators have no proof of this type.
The code is entered after choosing the plan, never before: with Ubigi, it is the data volume and duration that determine the price, and the discount is applied on top. And once the profile is installed, recharging from the app does not require a code: the discount applies to the first purchase, while proper sizing benefits all subsequent ones.
What 10% is worth on the Ubigi grid
A percentage discount pays in proportion to the price, so almost nothing on a small plan. Here is what 10% means on Ubigi's Japan grid, the destination we use as a yardstick across the site.
What 10% saves on Ubigi's Japan grid
Prices from our catalog, refreshed continuously from Ubigi's product feed. The discount follows the price: the smaller the plan, the more symbolic it gets.
The reading never changes: the code saves a few cents on a top-up plan and a few euros on a large one. Picking the right plan weighs ten times more, which is why our data calculator will teach you more than any code.
Ubigi: what you are actually buying
Ubigi is not a reseller like the others: the brand belongs to Transatel, part of the NTT group, which runs its own roaming agreements. That is what explains the 200+ destinations and prices displayed in eight currencies, euro included.
The other particularity is the top-up: once the profile is installed, you add data from the app without reinstalling an eSIM or scanning a new QR code. On a trip that stretches out, that is time saved and one less profile in your phone settings.
To place Ubigi against the other providers on your destination, our Japan comparator shows the per-GB prices side by side, discounts applied.
Fake Ubigi promo codes and how to spot them
On this query, several sites list codes like UBIGI50, WELCOME30 or NTT20, presented as massive discounts. Those codes do not work.
The mechanism is always the same: a long list catches the click, and the only valid code in it is the one belonging to the site publishing it. A 50% discount on an eSIM does not exist, the sector's margins do not allow it.
Two reflexes are enough. Distrust any eSIM discount above 15%, and test the code in the basket before paying: the total on screen is the only judge. Our eSIM promo codes page applies that rule to every provider compared.
