The rat's advice: check that tethering is allowed on the plan you pick before paying. It is on most of them, not on all, and that is the kind of detail you discover too late on the ground.
The eSIMNEXA promo code that works in September 2026
Only one code to remember: ESIMRAT, 10% off your eSIMNEXA order, the rate granted to eSIMrat by the brand's publisher, the same as Esimzon, its twin shop. It is entered at the time of payment, in the discount field on the checkout screen.
There is no such thing as a 25% or 50% eSIMNEXA 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 actually works. On unlimited plans at €2.15 per day, 10% is a genuine discount.
The eSIMNEXA code active in September 2026
ESIMRATeSIMrat code, all orders-10%ESIMRAT is the code assigned to eSIMrat by the publisher of eSIMNEXA, to be entered on the order screen. The 25% or 50% discount codes displayed by aggregators have no proof of this type.
The code comes after choosing the duration, never before: at eSIMNEXA, which focuses on unlimited KDDI in Japan from three to thirty days, it is the number of days that determines the bill, and the discount is added on top. The price-per-day curve is almost flat, so the exact length of your stay is all that matters.
What 10% is worth on the eSIMNEXA grid
A percentage discount pays in proportion to the price, so not much on a small plan. Here is what 10% means on eSIMNEXA's Japanese unlimited plans, the destination we use as a yardstick across the site.
What 10% saves on eSIMNEXA's Japan plans
Prices from our catalog, fed continuously by eSIMNEXA's product feed. The discount follows the price: the smaller the plan, the more symbolic it gets.
The reading never changes: the code is worth a few cents on a top-up plan and a few euros on a large one. The choice of plan weighs ten times more, which is why our data calculator will teach you more than any code.
eSIMNEXA: what you are actually buying
In Japan, eSIMNEXA bets on unlimited data on the KDDI network, from three to thirty days, with a 300 GB fifteen-day plan alongside. The price per day barely moves with length: $2.50 over three days, $2.52 over a month.
The brand allows tethering on most of its plans and supports top-ups without reinstalling a profile. Two details that matter on a long stay, and that not every provider grants.
eSIMNEXA shares its publisher with Esimzon: same company, same contact details. The grids differ though, and price per gigabyte is what settles it. Our Japan comparator shows them facing each other.
Fake eSIMNEXA promo codes and how to spot them
Codes like NEXA50, ESIMNEXA30 or WELCOME25 circulate around the brand, copied from one site to the next without anyone ever trying them. None of them applies.
An affiliate code identifies the site that referred you: it does not unlock a bigger discount than the one negotiated with the provider. Hunting for better than the advertised rate is a waste of time.
Only one test counts, the one you run yourself on the payment screen before confirming. The amount on display settles it, not a page's promise.
Our eSIM promo codes page applies that rule to every provider compared.

Frequently asked questions
ESIMRAT gives 10% off your eSIMNEXA order. It goes in at payment time, in the field meant for a discount code.
10% of the order. On the Japanese unlimited plans, that runs from 75 cents on three days to $7.55 on a full month.
Two common causes. The code was never submitted before payment, or another discount is already on the basket and the two do not stack. Always test the code before paying.
The discount is a percentage: it applies to the order amount whatever destination you pick.
The brand allows it on most of its plans, but not on all of them. The mention sits on the plan's own page: check it before paying if you intend to connect a laptop or a tablet.
Yes, topping up happens without reinstalling a profile or scanning a new QR code. On a trip that stretches out, that is what saves you buying a second eSIM.
Here: ESIMRAT, 10% off your order, the rate granted to eSIMrat by the publisher of eSIMNEXA. It is entered into the discount field on the order screen and is valid for all destinations in the catalog.
Two levers, in this order: choose the exact duration of your stay, since the price per day barely changes between three and thirty days, then use ESIMRAT when paying to get 10% off. The 300 GB fifteen-day plan is only worth it if you miss unlimited data speeds.
In our review, eSIMNEXA scores 3.8 out of 5: same publisher as Esimzon, unlimited KDDI in Japan at a stable daily price, data sharing allowed, but very little customer feedback, with no Trustpilot reviews noted in September 2026.
