How to use the Roamify promo code

Roamify sells across 239 countries and 27 zones, with plans from 1 to 1,000 GB valid 1 to 365 days, unlimited formats included. The code goes in at payment time.

  1. 1Pick your planRoamify slices by volume AND by length, 1 to 1,000 GB over 1 to 365 days: the widest grid in the comparator.
  2. 2Open the promo code fieldOn the payment screen, unfold the row reserved for the discount code.
  3. 3Apply and check the totalType ESIMRAT, submit, and watch the amount recompute before you pay.

The rat's advice: with 38 plans for Japan alone, the trap is not the code, it is picking the wrong line. Compare the price per gigabyte of two or three neighbouring rows before choosing: the gap between them dwarfs 5%.

The Roamify promo code that works in September 2026

Only one code to remember: ESIMRAT, 5% off your Roamify order, applied automatically via our link. On September 22, 2026, we added it to the cart for the 15-day unlimited Japan plan: $34.50 reduced to $32.77, "Order discount" line displayed by Roamify, no account needed and no payment required.

There is no such thing as a 30% or 50% Roamify 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. The 5% rate is what Roamify grants to its partners, and no one receives more.

ESIMRATeSIMrat code, all orders-5%

Test performed on the 15-day unlimited Japan plan for $34.50, without an account and without paying. The 30% or 50% discount codes displayed by aggregators have no proof of this type.

The code is entered after choosing your plan, never before: at Roamify, with 38 plans for Japan alone, the chosen line determines the price, and the discount is applied on top. Through our link, the "Enter promo code" field in your cart is already filled in.

What 5% is worth on the Roamify grid

A percentage discount pays in proportion to the price, so not much on a small plan. Here is what 5% means on Roamify's Japan grid, the destination we use as a yardstick across the site.

What 5% saves on Roamify's Japan grid

10 GB, 4 days$8.00 ·$0.40 saved
18 GB, 7 days$11.00 ·$0.55 saved

Prices from our catalog, fed continuously by Roamify'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.

Roamify, the widest grid in the comparator

For Japan alone, Roamify lines up 38 plans, from 10 GB over 4 days to 300 GB over 30 days, on the KDDI network. No other provider in our comparator slices this finely, which is both its strength and its trap.

Tethering is included everywhere, which is not the norm in eSIM, and prices show in euros as well as dollars. On very large volumes the price per gigabyte collapses: 100 GB costs barely more than 30 GB.

Still, 5% on an order is the lowest rate in our comparator. The gain therefore sits entirely in which line you pick, and our Japan comparator shows where Roamify lands against the rest.

Fake Roamify promo codes and how to spot them

Codes like ROAMIFY50, ROAM30 or TRAVEL25 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 5% off your Roamify order. It goes in at payment time, in the field meant for a discount code.

5% of the order. On the Japan grid, that runs from 40 cents on a 10 GB plan to $3.75 on the 100 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.

That is the rate Roamify grants. On their grid, the gap between two neighbouring plans weighs far more than the discount: that is where the saving is.

Yes, the brand advertises it across its plans. It is one of their arguments against providers that reserve it for certain formats.

Here: ESIMRAT, 5% off any order, added to cart on September 22, 2026, for the 15-day unlimited Japan plan, $34.50 reduced to $32.77. Through our link, Roamify fills it automatically in the cart's promo code field.

No. Roamify gives 5% to its partners, and that is the ESMRAT rate. Aggregators that display 10%, 30%, or 50% in their titles never show a cart where these codes actually apply.

In our review, Roamify scores 4.5 out of 5: the widest coverage in the comparator, KDDI network in Japan, data sharing included, and prices in dollars. Choosing the right plan matters much more than the 5% discount code.
