How to use the eSIM Card promo code
eSIM Card sells data plans across 209 countries and 18 regional zones, with unusually fine-grained durations. The code goes in at payment time, on the order.
- 1Pick your planeSIM Card slices finely: the same volume exists over 3, 5, 7, 10, 15 or 30 days, and the price follows the length.
- 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: on a grid this cheap, 10% is worth cents. The real gain sits elsewhere: take the right length rather than the longest one out of comfort, the gap between 7 and 30 days beats the discount.
The eSIM Card promo code working in September 2026
A single code, and it was added to the cart on September 22, 2026, for the one-day unlimited Japan plan: ESIMRAT takes 10% off, bringing the total from 6.97 $ to 6.27 $, with the "10% Discount" badge displayed by eSIM Card even before account creation.
The second code in the table is there for demonstration purposes: ESIMCARD50, the kind shown by aggregators, was rejected by the cart with the message "The promo code is not available for your destination." The 30% or 50% discounts promised in the headlines of these sites do not exist at eSIM Card.

The code is applied after choosing the plan, never before: at eSIM Card, one of the cheapest price lists on the comparison site, it's the data volume that determines the bill, and the discount is added on top. At this price level, 10% represents only a few dozen cents, but they are free.
What 10% is worth on the eSIM Card grid
A percentage discount pays in proportion to the price, so not much on a small plan. Here is what 10% means on eSIM Card's Japan grid, the destination we use as a yardstick across the site.
What 10% saves on eSIM Card's Japan grid
Prices from our catalog, fed continuously by eSIM Card'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.
eSIM Card: what you are actually buying
This is one of the cheapest grids in our comparator: $7.82 for 10 GB over 30 days in Japan, 78 cents a gigabyte, on the NTT Docomo network. At that level, the promo code becomes almost anecdotal.
The brand advertises 209 countries and 18 regional zones, plus an unlimited offer with a daily allowance. Prices are set in dollars, and any euro figure follows their site's conversion rate.
The duration grid is unusually fine: the same volume exists over 3, 5, 7, 10, 15 or 30 days, cents apart. That is what lets you match the real length of a trip, and our Japan comparator shows where it places them against the rest.
Fake eSIM Card promo codes and how to spot them
On this query, several sites list codes like ESIMCARD50, CARD40 or WELCOME30, 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 belongs 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.

Frequently asked questions
ESIMRAT gives 10% off your eSIM Card order. It goes in at payment time, in the field meant for a discount code.
10% of the order. On the Japan grid, that runs from 21 cents on a 1 GB plan to 78 cents on the 10 GB thirty-day one.
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.
Because 10% of a low price is little. On a 1 GB plan at $2.05, the discount is 21 cents. The starting price is what does the work here, not the code.
The brand advertises an unlimited offer with a daily allowance, alongside its volume plans. The allowance and what happens past it sit on the plan's page, worth reading before buying.
Here: ESIMRAT, 10% off any order, added to cart on September 22, 2026, for a one-day unlimited Japan plan, $6.97 reduced to $6.27. It is entered into the "Do you have a promo code?" field on the checkout screen, before account creation.
