Best Yesim Promo Codes 2026
As of May 2026, the code ESIMSTASH gives 15% off all eligible Yesim eSIM plans and is currently one of the best overall codes for most purchases. If you are buying a smaller plan, the coupon code TRAVLISTS2025 may save you more depending on your cart total. (This is a third-party coupon code that I used for my test review.)
Discount Codes That Work
The screenshots show the actual checkout results I observed during verification.
| Code | Discount | Best For |
|---|---|---|
| ESIMSTASH | 15% off | Plans $41 and above |
| TRAVLISTS2025 | At least $6 off | Plans $40 and below |
There is no minimum spend required to use either code.
Which Code Should You Use?
It depends on the cost of the plan. Let’s take for example Yesim’s China eSIM with unlimited data for 15 days. It’s priced at $32.40, as of May 30, 2026. On this plan, using TRAVLISTS2025 will give you a flat $6 discount or 18.52% off. This is better than the Yesim coupon code ESIMSTASH, which only provides 15% off or a $4.86 discount.
On purchases worth at least $41, 15% gives you $6.1, which is better than the flat $6 discount. The two codes cannot be stacked, so I suggest checking your cart before checking out. Only apply the promo code once you’re sure that it will give you the higher discount rate.
| Purchase Amount | Best Code | Reason |
|---|---|---|
| Under $40 | TRAVLISTS2025 | Flat $6 beats 15% |
| $40 | Either | Both save the same |
| Above $40 | ESIMSTASH | 15% saves more than $6 |
Field Notes
—On TRAVLISTS2025. While retesting TRAVLISTS2025 for my Yesim eSIM review on May 23, 2026, an error message stating “You have already used this promo code. Please try another one.” appeared while I attempted checkout. At first I thought this was odd since I had not purchased a Yesim eSIM on the same account previously — until I remembered that I had already redeemed the first code on the same account on May 9. This is shown on the screenshot above.
Based on this test, once a promo code for first-time users has been registered, you will not have to input the code again in the future when you are ready to proceed with purchase. Simply toggle “Use Ycoins”, since the value of the promo code gets converted to Ycoins, Yesim’s currency, after registration.
- On ESIMSTASH. For testing purposes, I also tried to register Yesim coupon code ESIMSTASH to my account prior to my first checkout. The same error message appeared. Based on my testing, other first-time user promo codes could not be registered after one had already been registered on the same account.
How Much You Can Save With Code ESIMSTASH on Popular Destinations
To help you see the benefit of using our promo code, I gathered Yesim's pricing for their 10GB, 30-day plans. I checked the prices directly on their official website on May 30, 2026 and calculated the savings using the ESIMSTASH code (15% off). Do note that prices and discounts may change over time, and the $0.60 secure payment fee is also not included in the figures below.
| Destination | Plan Price | You Save (15%) | After Code |
|---|---|---|---|
| China | $22.80 | $3.42 | $19.38 |
| Egypt | $18.00 | $2.70 | $15.30 |
| Europe & UK | $19.20 | $2.88 | $16.32 |
| Japan | $25.20 | $3.78 | $21.42 |
| Thailand | $13.20 | $1.98 | $11.22 |
| Turkey | $16.80 | $2.52 | $14.28 |
| United Kingdom | $19.20 | $2.88 | $16.32 |
| Vietnam | $22.80 | $3.42 | $19.38 |
Based on these examples, the ESIMSTASH code typically saves between $1.98 and $3.78 on Yesim's 10GB, 30-day plans, depending on the destination.
Worth noting: While Yesim is competitively priced for many of the destinations above, pricing can vary significantly by country. During my comparison on May 30, 2026, a 10GB, 30-day Dominican Republic plan cost $52.80 on Yesim, compared with $21.00 on Ubigi for a broadly comparable plan. That is more than double the price. This is why I make sure to compare a few providers before purchasing.
I Tested Yesim’s eSIM, Not Just the Codes
I personally used Yesim in South Korea. I found the installation straightforward — it took under 10 steps and under 4 minutes to get connected. The internet speeds reached up to 210.2 Mbps in Seoul on the LG U+ network, and I received a human response from their support team in under 2 minutes when I ran into a hotspot issue.
That said, Yesim is not always the cheapest for single-country trips with heavy data needs. For those, Airalo or BNESIM will likely cost less. For flexibility across destinations and additional features like a free built-in VPN for iPhone users, I found that Yesim holds up well.
One important detail worth knowing that came out during my testing: even if the promo code discount was higher than the cart amount, which means I should have paid nothing ($0), Yesim charged a minimal $0.60 secure payment fee at checkout. Read our full Yesim eSIM review →
Yesim Rewards Beyond the Promo Code
Discount codes usually apply to your first order only. For repeat purchases, Yesim has an ongoing rewards system worth knowing:
Ycoins Cashback: Earn 5% back on every purchase, redeemable toward future plans
Referral Bonus: After spending €5, you will be able to refer a friend — both of you get a €5 credit. Note: you need to have spent at least €5 on Yesim before you can generate and share your own referral code

How I Verify Yesim Promo Codes
I find it frustrating when I take time to search for a promo code and copy one from a random website, only to find out that it is no longer working. If you’ve gone through that, you’ll probably know what I mean. That’s why I personally try to test the codes regularly at least once a month. Here’s how I do it:
I manually test codes through the official Yesim checkout flow before publishing
I recheck codes monthly and update status immediately if a code expires or stops working
Testing includes both website and app checkout, where applicable
Screenshots and timestamps are updated after each verification round
Real purchases are used during review testing when needed
If a code fails at your end, reach out via our contact page or message us on Facebook and we will investigate directly with the provider.
Purchase Receipt
I personally purchased this eSIM using my own account. Below is the receipt confirming the transaction.
