Hey buddy,

Travel eSIM revenue hit $1.8 billion in 2025. Up 85% from the year before.

Forecast to cross $8.7 billion by 2030.

Every traveler landing in a new country used to hunt for a local SIM card at the airport, or pay brutal roaming fees. Now they buy an eSIM before they even board the flight. Instant data, no physical card, no airport kiosk line.

544 million+ eSIM-compatible devices shipped in 2025 alone. That's the size of the audience who could buy from you.

Here's the part most people miss though. There are two completely different ways to be in this business, and one pays 5-10x more than the other.

Path 1: Affiliate

You sign up for Airalo's (or similar provider's) affiliate program. Get a unique link. Share it with your audience - travel blog, Instagram, YouTube, wherever.

Someone clicks, buys an eSIM, you earn a commission. Typically 5-12% of the sale.

In real dollar terms: roughly €0.40-0.96 per eSIM sold.

This is genuinely easy. Zero setup, zero inventory, zero customer service. But it's also low leverage - you're sending your audience to someone else's store, and you never see that customer again unless they click your link a second time.

Path 2: White-label reseller

You partner with a wholesale eSIM provider. They give you access to their network coverage and data plans at wholesale rates. You put your own brand on it - your own store, your own domain, your own pricing.

You mark up 50-150% above wholesale. You keep the customer's email. You can market to them again for their next trip.

Real example from current wholesale partner data: an equivalent eSIM that pays an affiliate €0.40-0.96 pays a white-label reseller roughly €4.64 gross profit per sale. That's 5-10x the margin, on the exact same product.

At 500 monthly sales, that's the difference between €200-480/month as an affiliate and roughly €2,320/month as a brand owner.

Why the gap is that big: as an affiliate, you're renting attention to someone else's brand. As a reseller, you own the brand, the pricing, and the repeat relationship.

The barrier to entry has genuinely dropped. Connectivity-as-a-Service platforms have made it possible to launch a branded eSIM business without building any telecom infrastructure yourself - you're plugging into existing global networks through a wholesale partner.

The addressable market is growing fast and isn't showing signs of slowing - both the dollar volume (85% year-over-year growth) and the device base (11% year-over-year growth in compatible devices) are expanding simultaneously.

And crucially: this product has zero physical inventory. No shipping, no stock to hold, no returns to process. It's a digital code delivered instantly.

Step 1: Decide your entry model based on what you already have

If you already have an audience (travel content, a newsletter, social following) - affiliate first is a reasonable, zero-risk way to test demand before committing to a white-label setup.

If you're starting from scratch or want the real margin from day one - go straight to white-label. The setup complexity is lower than it sounds now, thanks to Connectivity-as-a-Service platforms designed specifically for this.

Step 2: Pick a niche instead of competing generically

This is the single most important strategic decision, and it echoes something true across most saturated markets: the biggest players (Airalo, Holafly, GigSky) win on brand recognition and volume. You can't out-market them head-on.

Instead, own a specific angle they under-serve:

Long-term digital nomads - not the average 7-day tourist, but people who need month-long or renewable plans in specific popular nomad hubs (Lisbon, Bali, Mexico City, Chiang Mai).

A specific region or country cluster - deep expertise and better plans for, say, Southeast Asia specifically, rather than generic "190+ countries" coverage everyone already offers.

A specific traveler type - business travelers who need reliability guarantees, backpackers who need the cheapest possible data, remote workers who need consistent high-speed data for video calls.

Step 3: Get set up with a wholesale/white-label partner

Research current wholesale eSIM providers (terms and specific partners shift, so check current offerings directly). Look for: global network coverage matching your target regions, an actual white-label storefront you can brand as your own, and API access if you eventually want to integrate eSIM sales into an existing website or booking flow.

Step 4: Build a simple branded store

You don't need custom development. Most white-label eSIM platforms give you a store on your own domain out of the box - you're mainly handling branding, pricing, and positioning, not building infrastructure from scratch.

Step 5: Price with real margin, not race-to-the-bottom

Mark up 50-150% above your wholesale cost. This sounds aggressive until you remember: customers are comparing your price against what airport SIM kiosks and roaming fees would have cost them, not against wholesale telecom rates they'll never see.

Step 6: Pick ONE distribution channel and go deep before adding more

Don't spread thin across five channels at once. Pick the one closest to your existing strengths:

If you know travel agency owners personally, start there - offer them a white-label or referral partnership where they resell to their own clients.

If you're strong on short-form content, build out a TikTok/Reels presence specifically around "don't get scammed by airport SIM kiosks" and similar practical travel content.

If you have any existing travel-adjacent audience (even small), email/newsletter promotion converts well since eSIM is genuinely useful, not a hard sell.

Get one channel to a solid 50 customers before adding a second.

Step 7: Build the repeat-customer engine

This is where white-label actually pays off versus affiliate. You have the customer's email. Their next trip is coming eventually.

Simple automated email 2-3 months after purchase: "Heading somewhere new? Here's 15% off your next eSIM." Low effort, meaningfully boosts lifetime value per customer.

Step 8: Layer in a B2B angle once you're established

Once your own consumer store is running, the bigger scale move is supplying eSIM access to other businesses - travel agencies, tour operators, booking platforms - who want to offer it to their own customers without building telecom relationships themselves.

One solid B2B partner relationship can produce more volume than dozens of individual retail customers combined.

Affiliate path (low effort, low ceiling):

500 monthly sales at €0.40-0.96 commission = €200-480/month

Realistic for someone layering this onto an existing travel content audience as one income stream among several.

White-label reseller path (real effort, real ceiling):

500 monthly sales at roughly €4.64 gross profit = approximately €2,320/month

1,000 monthly sales at the same margin = approximately €4,640/month

Add a B2B wholesale/referral partner sending consistent volume, and this scales meaningfully further without proportional extra marketing effort on your part.

Niche bundle premium:

A well-positioned niche offer (long-term nomad plans, a specific under-served region) can support pricing above the generic 50-150% markup range, since you're not competing purely on price against the big generic providers.

Month 1-2:

Pick your model (affiliate to test, or white-label to commit). Set up store or affiliate links. Choose your niche angle and primary distribution channel.

Revenue: $0-200 (early testing, first sales trickling in)

Month 3-4:

First real sales volume through your chosen channel. Refining messaging, pricing, and niche positioning based on what's actually converting.

Revenue: $300-800/month

Month 5-8:

Consistent sales through your primary channel, starting to layer in a second channel or the beginnings of a repeat-customer email flow.

Revenue: $800-2,000/month

Month 9-12:

Established brand within your niche, repeat customers contributing meaningfully, possibly a first B2B/referral partner in motion.

Revenue: $1,500-3,500/month

Year 2:

Multiple distribution channels running, B2B partnerships adding volume, niche positioning established as the go-to for your specific traveler type.

Revenue: $3,000-5,000+/month, with meaningfully higher ceiling if a B2B partnership scales well

P.S. - The affiliate-versus-reseller gap here is worth sitting with for a second, because it's a pattern that shows up everywhere, not just eSIM.

Renting someone else's brand and audience relationship (affiliate) is easy to start and genuinely fine as a test. But it caps out fast - you're always working for pennies on someone else's storefront, with no ownership of the customer relationship.

Owning the brand, the pricing, and the customer email (white-label reseller) takes more setup, but the same sale is worth 5-10x more, and every customer can come back for their next trip without you spending another dollar acquiring them.

That's not really an eSIM-specific lesson. It's true of affiliate marketing versus owning distribution in general.

Start this week. If you have any travel-adjacent audience already, sign up for one eSIM affiliate program today and get your first link live - zero risk, real signal on whether this converts with your specific audience.

If early sales look promising, that's your green light to move to a white-label setup and capture the real margin instead of leaving it with the affiliate program.

Worst case: you test a low-effort income stream and learn whether your audience actually buys travel products.

Best case: you validate demand cheaply, then flip to owning the customer relationship and the 5-10x margin that comes with it.
