How to use the GoMoWorld promo code
GoMoWorld is the travel eSIM of eircom, Ireland's incumbent carrier, sold across 193 countries in 1, 7 or 30 day plans. The code goes in at payment time.
- 1Pick your planGoMoWorld sells big: its Japanese plans start at 3 GB and climb to 45 GB over 30 days.
- 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: GoMoWorld's large volumes only pay off if you use them. Before taking 45 GB, look at what you actually used last month: the 14 GB plan already covers a three-week trip for most travellers.
The GoMoWorld promo code that works in September 2026
Only one code to remember: ESIMRAT, 10% off your GoMoWorld order, created by the brand for eSIMrat on September 1st, 2026 and applied automatically via our link. On September 18th, 2026, the pricing grid already showed the discount after clicking: the plan at €29.99 struck through, with €26.99 displayed below.
There is no such thing as a 25% or 40% GoMoWorld 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. All GoMoWorld partner codes are worth 10%, and none offer more.
The GoMoWorld code seen applied on September 18, 2026
ESIMRATeSIMrat code, all orders-10%Discount observed on the GoMoWorld pricing grid after clicking our link: €29.99 struck through and €26.99 displayed. The 25% or 40% codes shown by aggregators have no proof of this type.
The code is applied after choosing your plan, never before: with GoMoWorld, tailored for high data usage, it's the number of gigabytes that determines the price, and the discount is added on top. Through our link, the discount is already visible in the pricing grid; otherwise, the "Promo" field on the payment screen will apply it.
What 10% is worth on the GoMoWorld grid
A percentage discount pays in proportion to the price, so not much on a small plan. Here is what 10% means on GoMoWorld's Japan grid, the destination we use as a yardstick across the site.
What 10% saves on GoMoWorld's Japan grid
Prices from our catalog, fed continuously by GoMoWorld'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.
GoMoWorld, an incumbent carrier's eSIM
Behind the brand sits eircom, Ireland's incumbent operator. This is not a reseller set up for the occasion: the group runs a network at home and negotiates its roaming agreements elsewhere.
The offer is cut for large volumes: in Japan the grid starts at 3 GB over 7 days and goes up to 45 GB over 30 days. That fits work use or tethering, less so a three-day stay.
Prices are shown in euros, dollars and seven other currencies, which avoids a surprise conversion at payment. To place these plans against the rest, our Japan comparator ranks them on price per gigabyte.
Fake GoMoWorld promo codes and how to spot them
Search for “GoMoWorld promo code” and you will meet codes like GOMO50, WORLD40 or EIR30, advertised with reductions nobody has ever watched apply. They do not work.
Those lists exist for a simple reason: the longer they are, the more clicks they catch, and only one code on them is actually live, the one belonging to the site publishing the list. The rest is scenery.
The counter is one line long: type the code into the basket and watch the total. If it does not move, the code is dead, whatever the promise printed beside it.
Our eSIM promo codes page applies that rule to every provider compared.

Frequently asked questions
ESIMRAT gives 10% off your GoMoWorld 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 50 cents on a 3 GB plan to $3.50 on the 45 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.
eircom, Ireland's incumbent carrier, which sells its travel eSIM under this brand across 193 countries and 7 regional zones.
Its grid is built for large volumes over 30 days. For two or three days, providers that slice durations more finely often come out cheaper.
Here: ESIMRAT, 10% off your order, created by GoMoWorld for eSIMrat on September 1st, 2026. Through our link, the pricing grid will already show the discount, with €29.99 crossed out and €26.99 below it on September 18th, 2026; otherwise, enter it in the "Promo" field on the payment screen.
All GoMoWorld partner codes are worth 10%, and ESIMRAT is one of them. A code is therefore never "better" than another at GoMoWorld; the 25% or 40% offered by aggregators are never actually shown in a cart.
In our review, GoMoWorld scores 3.9 out of 5: an eSIM from eircom, the historic Irish operator, offering very large data volumes at good prices, but with uncompetitive add-on plans and a mandatory account before paying.
