If you search for the best eSIM affiliate program, you will find a wall of headline percentages: 10%, 15%, 20%, "up to 30%". What almost none of those pages tell you is the single fact that decides your actual income: is the commission one-off or recurring? A 30% cut of one $20 purchase is $6, once. A 20% cut of every payment a travel-heavy customer makes for years is a different asset class. This comparison lays out the real advertised rates of the major programs, gives credit where it is due, and then does the arithmetic most affiliate pages avoid.
How eSIM affiliate programs actually work
Nearly every eSIM affiliate program follows the same template, usually run through an affiliate network like Impact, Awin, or ShareASale:
- Attribution by cookie. You share a tracking link; if the visitor buys within the cookie window (typically 30 days), the sale is credited to you.
- Commission on the sale, one time. You earn a percentage of that purchase. When the same customer comes back three months later and buys directly, you usually earn nothing — the cookie is long gone.
- Payout via the network. Bank transfer or PayPal, monthly, sometimes with a minimum threshold.
This model was designed for products people buy once. eSIM data is the opposite: frequent travelers, digital nomads, and increasingly AI agents buy connectivity again and again. That mismatch — recurring spend, one-off commission — is the gap a small number of programs, Roamzy included, are built around.
The 2026 comparison table
Rates below are as advertised by each program or reported by affiliate networks at the time of writing; several vary by region, network, and negotiated tier, so treat them as starting points and verify before signing up.
| Program | Advertised rate | One-off or recurring | Attribution | Payout |
|---|---|---|---|---|
| Airalo | ~10% (some listings advertise up to 12%) | One-off per verified sale | Cookie, via Impact | Bank or PayPal via Impact |
| Holafly | 10% standard; advertised as negotiable up to 20% for high-volume partners | One-off per sale | 30-day cookie (Impact / Awin / ShareASale) | Monthly, low minimums |
| Saily | 15% per new user (10% on some regional networks) | One-off, new customers | 30-day window | Via affiliate network |
| Nomad | From ~10% affiliate; user referral is $5 + $5 credit, capped at 5 friends | One-off | Network cookie | Monthly |
| Maya | Advertised as 20% per new user | One-off | Not publicly stated | Via program |
| eSimNow | Advertised as up to 30% per sale | Per referred sale | Link, QR, or promo code | Weekly — bank, UPI, or PayPal |
| nadanada | 5% on eSIM sales (15% on VPN) | Per referred sale | Link-based | Monthly in Bitcoin, min 100k sats |
| Roamzy | 20% of every real cash payment | Recurring, forever | Bound to the referred account, no cookie expiry | USDT, min 50, manual approval |
Some honest credit before the math. Airalo is the biggest brand in the space, and brand recognition converts — a mediocre rate on a link people actually click can out-earn a great rate on one they don't. eSimNow's up-to-30% with weekly payouts is genuinely the fastest cash cycle on this list. nadanada deserves credit for two things few others do: Bitcoin payouts for a privacy-first audience, and a dedicated page for AI agents with an open, no-auth catalog API.
The recurring math: where 20% beats 30%
Here is the part the headline percentages hide. Assume a referred user who tops up $20, five times over a year or two — a normal pattern for a frequent traveler on a global eSIM, and an almost guaranteed pattern on Roamzy, where pricing is metered per megabyte and the balance never expires, so people keep one eSIM and refill it instead of buying a new package each trip.
| Top-up event | 30% one-off (first sale only) | 15% one-off (first sale only) | Roamzy 20% recurring |
|---|---|---|---|
| Top-up 1 — $20 | $6.00 | $3.00 | $4.00 |
| Top-up 2 — $20 | $0 | $0 | $4.00 |
| Top-up 3 — $20 | $0 | $0 | $4.00 |
| Top-up 4 — $20 | $0 | $0 | $4.00 |
| Top-up 5 — $20 | $0 | $0 | $4.00 |
| Total | $6.00 | $3.00 | $20.00 |
Two fair caveats. First, per-sale programs like eSimNow can credit repeat purchases if the customer keeps buying through your link or promo code — but that depends on the customer's behavior, not on the program's design. Cookie-based programs generally stop crediting once the window closes. Roamzy's attribution is structural: the referral is bound to the referred account itself, so a payment made two years later still pays you 20%, with no link re-click required. Second, recurring only beats one-off if users actually come back — which is exactly why a pay-per-MB, never-expiring model is the natural substrate for it. A user paying $0.0014 per MB in Spain or $0.0021 per MB in Thailand has no reason to switch providers between trips; they just top up. (Full country list on the prices page, and the metered model itself is compared in our pay-per-MB provider roundup.)
The twist nobody else has fully built: AI agents as affiliates
Every program above assumes the affiliate is a human with a blog, a YouTube channel, or a coupon site. In 2026 that assumption is breaking. AI agents already buy connectivity on behalf of users, and an agent that recommends and provisions an eSIM is, functionally, an affiliate.
nadanada took the first step: a public AI-agents page and a read-only, no-auth catalog API that agents can query for plans and pricing. Roamzy goes further — the agent is not just a consumer of the API, it is a first-class referral account:
- Roamzy's MCP server (12 tools) is anonymous-first: an agent connects with no account, no API key, no KYC.
- That anonymous agent session gets its own referral code and earns the same 20% recurring commission on every real cash payment made by users it refers — accrual starts immediately, no claim needed to earn.
- Payments are settled in USDT/USDC stablecoins, which is what agent-side wallets can actually hold and spend — the same rail explored in our x402 piece on agent-native payments.
If you are building a travel assistant, a procurement bot, or any agent that touches connectivity, this means the agent can monetize its own recommendations. Details and setup are on the agents-earn page, and we compared agent-usable providers in best eSIMs for AI agents.
The honest fine print on Roamzy's program
There is also the honest brand question: Roamzy is not Airalo. A household-name link will convert cold traffic better than a challenger brand, and no recurring rate fixes a click that never happens. Roamzy's referral economics work best where the audience already values what Roamzy is: no-KYC, stablecoin-payable, one eSIM for 193 countries, metered per MB.
Who should pick what
- Mass-audience travel bloggers and YouTubers: Airalo or Saily. Recognizable brands, mature network tooling, PayPal/bank payouts. Lower rates, but the conversion funnel is proven.
- Coupon, deal, and high-volume resale channels: eSimNow. The advertised up-to-30% per sale with weekly payouts is the fastest money on this list if you move volume.
- Bitcoin-native and privacy audiences: nadanada (BTC payouts, low 5% on eSIMs but 15% on VPN) or Roamzy (USDT, higher eSIM rate, recurring).
- Long-horizon audiences — digital nomads, expat communities, crypto users who top up for years: Roamzy. This is where 20%-forever compounds hardest.
- AI agent builders: Roamzy is the only program in this comparison where the agent itself holds the referral account and earns recurring commission over MCP, anonymously.
Nothing stops you from running two programs at once: a big-brand one-off for cold traffic, and a recurring program for the readers and agents who will still be topping up in 2028.
FAQ
What is the highest-paying eSIM affiliate program in 2026?
On headline rate, eSimNow's advertised up-to-30% per sale is the highest one-off figure we found. On lifetime value per referred user, Roamzy's 20% recurring overtakes a 30% one-off from the referred user's second top-up onward, and keeps compounding after that.
Do eSIM affiliate programs pay recurring commissions?
Most do not. Airalo, Holafly, Saily, Nomad, and Maya advertise one-off commissions on referred sales, typically attributed through a 30-day cookie. Roamzy pays 20% of every real cash payment the referred account ever makes, with attribution bound to the account rather than a cookie.
Can an AI agent join an eSIM affiliate program?
On Roamzy, yes — an anonymous agent connected over the MCP server gets a referral code and accrues the same 20% recurring commission as a human affiliate; it must claim the account (add a contact) to withdraw. nadanada offers an agent-friendly read-only API, though its eSIM commission is 5% per sale. See the agents-earn page for setup.
How does Roamzy pay affiliates, and what are the limits?
Payouts are in USDT with a 50 USDT minimum and manual approval on each withdrawal. Earnings accrue automatically on every real cash payment by referred users; promo credits do not count. More detail in the FAQ.
Do I need a website to be an eSIM affiliate?
Usually not. Network-based programs accept social channels and newsletters, eSimNow issues links, QR codes, and promo codes, and Roamzy needs only a referral code attached to your account — human or agent.
