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 Yesim Promo Code • October 2026
Use TEE20 for 20% off your first esim purchase. It's a public code, not one of ours. We're now a Yesim affiliate, but Yesim hasn't given us our own discount code yet; we'll feature it here the moment that changes.
What Actually Makes Yesim Different
Most eSIM apps on this site sell you a fixed block of data and that's the end of the relationship until you buy again. Yesim's "Pay & Fly" plans work more like a prepaid balance: you buy data in dollars rather than gigabytes, it's priced from $1.10/GB, and whatever you don't use rolls over instead of expiring the moment your trip ends. If you're a frequent flyer who tops up the same balance trip after trip rather than buying a fresh block every time, that's a genuinely different model from the fixed-GB or fixed-day plans Airhub and most other providers here sell.
Yesim also advertises automatic network switching (they call it "SwitchLess Networks") across a claimed 800+ partner networks, so the eSIM hops to whichever local carrier gives the best signal instead of locking you to one partner network the way a lot of single-carrier eSIMs do. We haven't independently measured the switching in the field, so treat it as Yesim's own claim rather than something we've verified.

The Refund Policy Is Better Than Most eSIM Apps
Yesim advertises a 30-day money-back guarantee on unused plans, refundable through their own policy rather than just for eSIMs that fail to activate. Most providers on this site, including Yesim's own cheaper competitors, only refund a plan that never connected in the first place and treat any activated plan as final. That's worth knowing if you tend to buy ahead of a trip and aren't sure you'll actually use the plan.
The tradeoff is price. Yesim sits in our "Expensive" bracket: day-based plans run from roughly $1.56 to $31 depending on destination, noticeably above what Holafly or Airhub charge for comparable coverage. You're paying for the refund flexibility and the Pay & Fly balance model, not for the cheapest rate per GB.

Is Yesim the Right Pick for Your Trip
Good fit
- You travel often and want a data balance that rolls over instead of a plan that expires between trips
- You want the option of a real refund if you buy ahead and end up not needing the plan
- You'd rather pay in dollars for data used than track a fixed GB allowance
Consider alternatives
- You just want the cheapest rate for a single trip: check Airhub or Holafly first
- You want unlimited data with no usage tracking at all: see Holafly
- You want to buy data for a country now and use it later without a deadline: see BNEsim, whose no-expiration packs cost more than the 30-day versions
- You are only traveling within Europe and want calls and SMS included as standard: see Orange Travel
- You want a carrier-backed eSIM with a recurring monthly plan option for repeat trips: see Ubigi, a Transatel (NTT Group) brand
- You would rather buy a fixed per-country plan for one trip than keep a rolling balance: see Nomad, or read our Nomad vs Yesim comparison
What the Discount Looks Like

TEE20 only applies to your first Yesim purchase. After that, WELCOMETOYESIM (15% off) and TRAVELFREE (a flat €3 off) are the codes worth trying on repeat orders.

Yesim Promo Code FAQ
What is the best code right now
TEE20: 20% off your first esim purchase, for first-time buyers. Returning customers should try WELCOMETOYESIM or TRAVELFREE instead.
What is a Pay & Fly plan
It's Yesim's balance-based option: you top up a dollar amount rather than buying a fixed block of GB, priced from $1.10/GB, and unused balance carries over to your next trip instead of expiring.
Can I get a refund if I don't use the plan
Yesim advertises a 30-day money-back guarantee on unused plans, which is a step further than most eSIM providers on this site that only refund a plan that never connected at all. Refunds still run through Yesim's own policy, not through us.
Is Yesim the cheapest option
No. Yesim sits in our "Expensive" price bracket. If price per GB is your main concern, check Airhub or Holafly before buying.
Does Yesim include a phone number
No. It's data-only, like most eSIMs on this site. Voice calls run over apps like WhatsApp or Viber using the data connection.
