Travel eSIM has become one of telecom’s clearest growth stories. Juniper Research estimates $ 1 million in 2024, and forecasts $8.7 billion by 2030. Travellers are moving away from conventional roaming and local SIM-card queues. What those figures do not reveal is whether the companies selling the packages are building healthy businesses.

The barrier to launching an eSIM brand has fallen quickly. Connectivity-as-a-Service platforms can provide inventory, provisioning and APIs without a new entrant owning a network. That has encouraged innovation, but also crowded the retail layer with brands selling similar plans for the same destinations. Juniper identifies these platforms as a force lowering market-entry barriers. Counted price is the real price

New-user offers, influencer codes, referral credits and publisher discounts now shape the normal eSIM shopping journey. Once customers assume a code is available, the displayed figure becomes an anchor rather than the expected selling price.

Discounting can introduce a nervous first-time user. Trouble starts when it becomes permanent and disconnected from customer lifetime value.

Consider an illustrative €10 plan discounted by 15%. Revenue falls to €8.50. If the sale came through an affiliate earning 10% of the final value, another €0.85 goes. Payment processing then takes a percentage and often a fixed fee. Before data, support, refunds, fraud, technology and staff, the original $10 product may already resemble a €7 transaction.

Airalo lists a standard 10% affiliate commission after discounts; Saily advertises 15% for each new user; Yesim starts at 10% and also pays on repeat purchases from referred customers. Negotiated deals can differ, but distribution is clearly not free.

The issue is not whether affiliates work. It is whether providers know which partners create incremental, repeat customers and which merely intercept buyers already ready to purchase.

Growth can become rented demand

The same pressure appears in paid search and social advertising. A traveller searching for an eSIM for Japan, Turkey or the United States has immediate purchase intent. Every major provider, comparison site and increasingly every telecom brand wants that click.

When companies bid for the same traveller, acquisition cost can rise faster than package prices. A provider may report more installs and first purchases while spending heavily to obtain customers who disappear after one trip.

The dynamic resembles online travel agencies: whoever controls customer access has leverage, while businesses dependent on performance marketing rent demand.

Airalo’s $220 million funding round in 2025, at a valuation above $1 billion, shows the scale of capital entering the category. The company said it served more than 20 million travellers across 200-plus destinations. That is formidable—and a reminder of the gap between a scaled platform and a small reseller trying to win the same search with a similar country package. ned audience, differentiated product or embedded partner, retail eSIM is an expensive place to learn that volume does not equal profitability.

Wholesale economics change by destination

“Cost per gigabyte” sounds simple. In practice, wholesale economics vary by country, network, volume commitment, routing architecture, service quality and supplier relationship. A provider can earn an attractive margin in one destination and a weak one in another, even when the retail products look identical.

That becomes dangerous when comparison pages push brands toward a globally consistent “cheap” position. Cutting a Europe package by 10% may be manageable. Applying the same pricing instinct to a costly island market, a destination with limited network options or premium 5G access can erase contribution margin.

Providers need profitability by country, package, supplier, channel and cohort—not one blended percentage that lets strong destinations conceal bad ones.

The supply chain matters too. A reseller buying through several intermediaries has less room than a provider with direct operator agreements, core-network capabilities or enough volume to negotiate stronger terms. Research into Airalo’s architecture shows how travel eSIM delivery can involve multiple base operators and geographically separate internet gateways rather than one simple wholesale relationship. d has a variable cost

Unlimited plans solve a genuine customer problem. Travellers do not want to calculate whether maps, video calls, hotspot use and social media will consume 10GB or 20GB. “Unlimited” replaces that anxiety with a simpler promise.

For providers, it is an exercise in usage distribution. Most customers consume moderate amounts. A smaller group will tether laptops, stream heavily or use the plan as temporary home broadband. Profitability depends on average usage remaining predictable and extreme consumption being managed through pricing, hotspot rules, network policy or clearly disclosed fair-use terms.

Vague wording creates another expense. When marketing says unlimited but the practical experience includes traffic management or reduced speeds, customers contact support, request refunds and complain. The cost is not only data; it is the operational burden created by a promise interpreted differently by seller and buyer.

Holafly has built a premium position around unlimited travel data and reported more than $500 million in cumulative revenue, including about $200 million in 2024. It has also expanded into global monthly plans for frequent travellers. Recurring revenue creates more opportunities to recover acquisition cost than isolated holiday purchases. work. It is simply a poor imitation strategy for a provider lacking usage analytics, pricing discipline and transparent fair-use communication.

Small sales carry large friction

Payment costs look minor until applied to low-value orders. Card processing commonly combines a percentage with a fixed fee, while international cards and currency conversion can cost more. The fixed element bites much harder on a €4 package than on a €50 regional plan. An eSIM is delivered instantly and can be consumed before a suspicious payment is resolved. A chargeback may remove the revenue, leave the provider with the data cost, and add a dispute fee. Stripe has said chargebacks can cost businesses more than twice the original transaction after lost revenue, fees and evidence handling.

Operational events, not just accounting reversals. Teams must determine whether an eSIM was installed, activated, partly used or technically faulty. Saily offers a full refund within 30 days for a plan not installed or activated, while activated-plan cases require more assessment. Flexible policies can improve trust, but need reliable usage data and automation. Similar economics. A traveller who cannot connect at midnight does not care that the plan cost €6. Resolving it may require device-specific instructions, screenshots, APN checks, manual network selection and supplier escalation. Low order values do not produce low support expectations.

Retention is the missing metric

Many providers still optimise for the first transaction. Yet a customer who buys once for a summer holiday and returns to a domestic operator leaves little time to recover acquisition cost.

A stronger model reduces the need to choose again. Reusable profiles, stored balances, regional wallets, loyalty benefits, annual packages and monthly global subscriptions can turn connectivity from a disposable purchase into an ongoing relationship.

Embedded distribution deserves equal attention. An airline, bank, OTA, hotel group or corporate travel platform can place connectivity inside an existing journey, reducing dependence on paid search when every provider is bidding for the same traveller. B2B distribution carries revenue share and integration costs, but can offer repeat volume, stronger context and lower acquisition friction.

Not every provider should become a subscription company; occasional travellers may prefer one cheap package. The mistake is expecting one-time customers to create retention by themselves.

Conclusion

The travel eSIM market does not have a demand problem. It has a value-capture problem.

The likely winners will not necessarily offer the lowest destination price or longest country list. They will understand contribution margin at package level, control more distribution, retain customers between trips and give connectivity a role beyond “cheaper than roaming.”

Airalo represents the capital-and-scale route. Holafly is moving a premium unlimited proposition toward recurring global plans. Saily benefits from the brand and marketing ecosystem behind Nord Security. Infrastructure-led and operator-backed players can compete through network control, direct agreements and enterprise distribution. Smaller providers still have room, but copying a larger rival’s catalogue and adding a bigger coupon is not durable. e will reward better economics rather than louder growth claims: fewer indiscriminate promotions, clearer unlimited policies, smarter fraud controls, stronger self-service support and products designed for the second, third and tenth purchase.

Travel eSIM sales are growing. Provider margins may grow too—but only when the industry stops treating every new order as proof that the business model works.
