eSIMCard Discount Code: How Much You Can Really Save

eSIMCard is one of the broadest catalogs eSIMKart tracks — 76 of the 77 destinations we cover, over 1,700 active plans — and it runs a real, working 10% promo code. Like every code on this site, it's read live from the same database that prices every plan below, not typed out once and left to go stale.

What eSIMCard Actually Offers

eSIMCard covers 76 countries with 1,702 active plans, prices ranging from $1.19 up to $318.12 and averaging around $33.65. One genuinely complete data point: every single plan in the catalog reports real hotspot/tethering support — 1,702 out of 1,702 — which isn't something every provider's feed gives us enough to confirm at that scale.

How Much the Code Actually Saves You

Here's what the current code works out to on real eSIMCard plans:

United States

• 1GB / 3 days: $1.92 → $1.73 (19 cents off)
• 5GB / 30 days: $7.17 → $6.45 (72 cents off)
• 10GB / 30 days: $12.86 → $11.57 ($1.29 off)
• Unlimited / 30 days: $36.10 → $32.49 ($3.61 off)
• 100GB / 30 days: $87.02 → $78.32 ($8.70 off)

United Kingdom

• 1GB / 3 days: $1.39 → $1.25
• 5GB / 30 days: $4.67 → $4.20
• Unlimited / 30 days: $22.75 → $20.48
• 100GB / 30 days: $54.58 → $49.12

Japan

• 1GB / 3 days: $1.54 → $1.39
• 1GB / 30 days: $2.05 → $1.85
• 10GB / 30 days: $7.82 → $7.04
• Unlimited / 30 days: $60.57 → $54.51
• 100GB / 30 days: $146.50 → $131.85

You can see these same plans — and every other real eSIMCard tier for these destinations — on the live country pages: eSIMCard's US plans, eSIMCard's UK plans, or eSIMCard's Japan plans. The figures above are those live prices with the code applied on top.

How to Actually Use the Code

Enter the code shown above at eSIMCard's checkout — it's a straight percentage off, applied immediately at checkout rather than a credit or cashback mechanic.

As with any tracked code, reach eSIMCard's checkout through a link on this site — the "Get eSIM" button on a plan, or the discount card above — rather than a plain search result, since referral-tracked codes can fail to apply from an untracked path.

Is the Discount Code Automatically the Best Deal?

A 10% code is a real saving, but it's 10% off eSIMCard's price specifically — it doesn't tell you how that compares to a different provider's plan for the same destination. Every country page on this site sorts by real price and shows price-per-GB and price-per-day, so you can compare eSIMCard against every other provider fairly before deciding the code makes it the best option. Our guide on how to compare eSIM prices before you buy covers the method in more detail.

Not Every Destination Gets the Same Granularity

One real thing worth knowing before you shop: eSIMCard's plan granularity varies a lot by country. The US and UK examples above follow a fairly typical structure — around 22 tiers each, mostly at 3, 7, 15, and 30-day marks. Japan is a different story: eSIMCard sells roughly 47 distinct plans there, with data sizes from 1GB up to 100GB individually priced at nearly every duration from 1 to 30 days, plus a 90-day option. If you're headed to Japan specifically, it's worth checking the actual country page rather than assuming the same handful of options exist everywhere — you may find a size/duration combination tailored much more closely to your actual trip length than the standard tiers other destinations offer.

FAQ

Does the eSIMCard code expire? It might — codes are set by the provider and can change or lapse without notice. This page reads the code live rather than printing a fixed one, so whatever's shown above right now is genuinely active today.

Is this a one-time code or does it apply to every purchase? eSIMCard hasn't specified either way to us, so rather than guess, this page just tells you plainly: check the code box above at the time of your purchase, whether it's your first or a later one.

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 eSIMCard's own promo code, and nothing stops both from applying if eSIMCard's checkout allows it.

Why does the number of plan options vary so much by destination? That's a genuine, real difference in how eSIMCard has built out each country's catalog, not an inconsistency worth worrying about — some destinations (like Japan above) get very fine-grained day-by-day pricing, while others follow a more standard multi-tier structure. Check the specific country page for your trip rather than assuming.

Does every eSIMCard plan support hotspot/tethering? Yes — confirmed on all 1,702 active plans we track, a rare case of 100% coverage on that specific data point across an entire catalog this size.
