Heads up: some codes on this page are affiliate codes and links, including our own (ADAMANDLINDS where it applies). If you use one, we may earn a commission. We put our own code higher up on the page because it's ours, not because it's automatically the best deal. Every code here is confirmed still active by us, but check the list before you copy: a public code below ours might save you more. See our about page for the full breakdown.
Best eSIM Card Promo Code • October 2026
Use ESIM10 for 10% off any eSIM Card plan. It's a public code rather than one of ours (eSIM Card doesn't run the kind of affiliate program that lets us put our own code on it the way we do for Holafly or Ubigi), and we found it advertised directly on eSIM Card's own homepage, not just on a coupon-aggregator site.
What Actually Makes eSIM Card Different
eSIM Card's real difference is how granular its own country pages are. Most providers on this site sell a handful of preset bundles per country: pick a data size, pick a length, done. eSIM Card's United States page alone lists roughly 30 combinations: seven fixed-data tiers (1GB, 3GB, 5GB, 10GB, 20GB, 50GB, 100GB) each sold at several different validity windows from 3 to 90 days, plus two separate unlimited tiers, "Unlimited" and "Unlimited Plus," running anywhere from 1 to 30 days. If you know exactly how much data and how many days you need, there's a plan sized for that instead of rounding up to whatever bundle a competitor happens to offer.
eSIM Card also runs a couple of things most data-only competitors don't: a separate Data + Voice eSIM product line, and a standalone virtual phone number add-on starting around $2.40, both sold inside the same app as its regular data plans. That's a similar idea to what AloSIM does through its Hushed partnership, but here the number is its own paid purchase rather than something bundled free with a data plan.

Two Things eSIM Card Doesn't Spell Out on Its Own Site
The fair-use language on eSIM Card's unlimited plans reads: "Unlimited bundles provide an allowed limit of data at full speed per 24 hours and thereafter unlimited data at lower speeds." That's their own wording, and it confirms tethering/hotspot works on unlimited plans and that the plan activates on first use rather than at purchase. What it doesn't do is give you the actual number: how many GB at full speed before the slowdown kicks in. Some competitors publish that figure directly (Saily, for instance, states 5GB in a rolling 24 hours in most destinations, 3GB in some); eSIM Card just says "an allowed limit" without naming one.
The refund policy is also stricter than it might look at a glance. eSIM Card's own policy page describes eSIMs as fundamentally non-refundable once installed or used, with refunds limited to narrow cases like a genuine coverage failure or a technical fault on their end where zero data was consumed, and even then a claim has to be filed within 30 days of purchase. Buy the plan you're confident about, not one you're hoping to test and return.

Is eSIM Card the Right Pick for Your Trip
Good fit
- You know your exact data need and trip length and want a plan sized to match, rather than rounding up to a preset bundle
- You want the option to add a virtual phone number or a voice-enabled eSIM from the same app you're already buying data through
- You're confident about the plan before you buy it, since there's little room to change your mind after it's installed
Consider alternatives
- You want a phone number bundled in for free instead of bought separately: see AloSIM, whose Hushed-partnered number comes at no extra cost
- You want a bigger bundle at a lower per-GB rate: Airhub's 3GB US plan works out to under $1/GB, cheaper per gigabyte than eSIM Card's smallest US tier
- You want an unlimited plan with a fair-use number actually published: see Saily
What the Discount Looks Like

eSIM Card Promo Code FAQ
What is the best code right now
ESIM10: 10% off any eSIM Card plan. It's a public code advertised directly on eSIM Card's own homepage, not one of ours.
Does eSIM Card sell unlimited plans
Yes, two tiers per country: "Unlimited" and "Unlimited Plus," each available at several validity lengths, on top of the regular fixed-GB plans. eSIM Card's own site doesn't spell out exactly what separates the two tiers beyond price.
Is eSIM Card's unlimited data actually unlimited
Per eSIM Card's own fair-use wording, unlimited bundles get "an allowed limit of data at full speed per 24 hours and thereafter unlimited data at lower speeds." The page confirms tethering/hotspot works on these plans, but doesn't publish the actual GB figure for that daily full-speed allowance the way some competitors do.
Can I get a phone number with eSIM Card
Yes, as a separate virtual phone number add-on starting around $2.40, purchased inside the same app as the data eSIMs rather than bundled in for free.
Can I get a refund
Rarely, once an eSIM is installed or used. eSIM Card's own refund policy describes eSIMs as fundamentally non-refundable, with exceptions limited to narrow cases like a genuine coverage failure or a technical fault with zero data consumed, claimed within 30 days of purchase.
