Yesim Discount Code: How Much You Can Really Save

Yesim has grown into one of the larger eSIM catalogs eSIMKart tracks — 2,223 active plans across 75 countries, every single one of them a genuine single-country plan (Yesim doesn't sell regional or multi-country bundles at all, unlike most providers on this site). It currently runs a real, working promo code for new customers, read live from the same database that prices every plan on this site — no stale code, no guessing whether it still works.

What Yesim Actually Offers

Prices across Yesim's catalog range from $0.52 up to $161.14, averaging around $41.87 per plan. The $0.52 figure isn't a typo or an error — it's a real 500MB/1-day tier, genuinely the cheapest single plan tracked across every provider on this site.

The catalog being 100% single-country plans (zero regional bundles) means Yesim isn't the pick if you're covering multiple countries on one trip — check the Global plans page for providers that sell multi-country coverage instead. But for a single-destination trip, it means every plan you see for your country is genuinely built for that country specifically, not a slice of a broader regional product.

How Much the Code Actually Saves You

Here's what the current code works out to on real Yesim plans, pulled from two countries:

United States

• Unlimited / 1 day: $3.37 → $2.70 (67 cents off)
• 1GB / 30 days: $3.60 → $2.88 (72 cents off)
• 5GB / 30 days: $10.45 → $8.36 ($2.09 off)
• 10GB / 30 days: $16.26 → $13.01 ($3.25 off)
• 20GB / 30 days: $24.39 → $19.51 ($4.88 off)
• 30GB / 30 days: $30.90 → $24.72 ($6.18 off)

Thailand

• 1GB / 30 days: $3.02 → $2.42 (60 cents off)
• 5GB / 30 days: $8.13 → $6.50 ($1.63 off)
• 10GB / 30 days: $12.78 → $10.22 ($2.56 off)
• 30GB / 30 days: $26.72 → $21.38 ($5.34 off)

United Kingdom

• 1GB / 30 days: $2.90 → $2.32 (58 cents off)
• 5GB / 30 days: $11.15 → $8.92 ($2.23 off)
• 10GB / 30 days: $18.59 → $14.87 ($3.72 off)
• 30GB / 30 days: $32.52 → $26.02 ($6.50 off)

You can see the actual live prices — and every other Yesim plan for these destinations — on the country-specific plan pages, for example Yesim's US plans, Yesim's Thailand plans, or Yesim's UK plans. Those numbers are the real, current price shown at checkout; the figures above are the code applied on top.

The pattern scales cleanly with plan size: roughly 60-70 cents off the smallest tiers, climbing past $6 off on the biggest 30GB plans.

How to Actually Use the Code

Enter the code shown in the box above at Yesim's own checkout when you buy a plan — it's a straightforward percentage-off code, not a cashback or wallet-credit scheme, so the lower price shows up immediately once applied.

One thing worth flagging, because it trips people up on codes generally: reach Yesim's checkout through a link on this site (the "Get eSIM" button on any plan, or the discount card above) rather than through a plain search result or an old bookmark. Some promo codes are tied to a tracked referral link and may not apply if you land on the provider's site from an untracked path.

Is the Discount Code Automatically the Best Deal?

Worth being direct about this: a 20% code is a real saving, but it's 20% of Yesim's price for a given plan — it says nothing about how that price compares to a different provider's plan for the same destination. A provider with no code at all can still land cheaper overall than Yesim-with-a-code, if their starting price was lower to begin with.

The more reliable way to shop is to check the actual cheapest plan for your destination first — every country page on this site sorts by real price and shows price-per-GB and price-per-day so you can compare fairly across differently-sized plans — and then see whether Yesim's code makes sense for what you need. Our guide on how to compare eSIM prices before you buy walks through this in more detail.

FAQ

Does the Yesim code expire? It might — codes are set by the provider and can change or lapse without notice. That's why this page reads the code live instead of printing it as fixed text: whatever's showing in the box above right now is genuinely active today.

Is this a one-time code or does it apply to every purchase? Yesim's current code is a first-purchase-only discount, applied on your first order — it's not designed to be reused on every future top-up.

Can I stack this with a price-drop badge I see on a plan? Yes. A price-drop badge just means that specific plan's price recently fell from what it used to be — it's unrelated to Yesim's own promo code, and nothing stops both from applying if Yesim's checkout allows it.

Do I need an account with Yesim before the code works? You'll typically create your Yesim account as part of checkout, then enter the code before completing payment — check Yesim's own checkout flow for the exact step, since that mechanic is set by the provider, not by us.

Why is the cheapest plan only 500MB for 1 day? It's a genuinely real, tiny entry-level tier — useful if you just need to get a map working or send a few messages right after landing, not a plan meant to cover a full trip. Every other tier above it scales up from there; it's listed here because it's real data, not because it's the plan most travelers should actually buy.

Plan Structure: What Makes Yesim Different

Yesim's real standout is duration granularity. Most providers on this site pick a handful of fixed validity periods — 7, 15, 30 days — and that's it. Yesim sells a distinct plan for every single day from 1 to 30. If your trip is 11 days, there's a real 11-day plan rather than forcing you to round up to a 15- or 30-day tier and pay for data you won't use.

That granularity is worth factoring in alongside the discount code itself: on an oddly-timed trip, picking the plan that actually matches your travel dates can save more than the 20% code does on its own.

What Happens on Your Next Purchase

Worth setting expectations here: Yesim's code is a first-purchase discount, not a standing account benefit. If you buy a plan now, use it on your trip, then need a second one later — a top-up, a renewal, or a plan for your next trip — that purchase is priced at Yesim's normal rate, with no automatic discount applied. If you're a frequent traveler who expects to buy from Yesim repeatedly, it's worth checking back on this page or the coupons page before each purchase, since providers do periodically run fresh promotions beyond the standard first-purchase one.
