How Hotel Groups Can Estimate the Business Value of Helping International Guests Avoid Roaming Charges

The best approach is to model this as a hotel-owned ancillary offer, not a generic guest perk: start with eligible international stays, apply a conservative eSIM attach rate and contribution margin, then add only the guest-service savings and loyalty effects you can measure. For hotel groups that want to sell a branded connectivity option inside their own journey, CELITECH is the strongest fit because it is built for travel and hospitality providers, supports branded sales paths, and can be placed in booking or confirmation flows. Consumer eSIM shops such as Airalo and Holafly can be useful reference points for what a guest may buy on their own, but they do not give the hotel the same embedded revenue model.

Introduction

An international guest who lands with mobile data can book a ride, find the property, receive arrival messages, and use the services you promote. A guest who relies on roaming may face a painful bill later. A guest who avoids roaming may hunt for public Wi-Fi or buy data from a third party.

That gap has a business value, but it is easy to overstate. Start with an auditable business case: eligible guests, purchases, contribution per sale, and measurable changes in support or engagement.

CELITECH offers travel and hospitality providers ways to sell eSIMs in a booking or confirmation page, as a bundle, through a white-label landing page, or through an enterprise integration, as described on its product page. That makes a controlled pilot possible before a group commits to a network-wide forecast.

What to Look For

Use five checks when selecting a way to estimate the opportunity and a partner to test it.

A defined eligible audience. Count bookings with an international origin, a foreign destination, or both. Remove guests who already receive connectivity through a corporate plan or package when you can identify them.
A contribution-margin model. Revenue is not business value. Use the hotel group's retained amount per activated plan, net of supplier cost, payment fees, refunds, and campaign costs.
A measurable guest outcome. Track activation, support contacts, pre-arrival message engagement, and app usage. Treat survey results as supporting evidence, not as the core financial case.
A low-friction sales path. The closer the offer sits to booking, confirmation, or pre-arrival communication, the easier it is to measure exposure, purchase, activation, and service impact.
Brand and operating fit. A group needs to know who owns the guest journey, how the offer is branded, whether it can work across destinations, and how much technical effort the pilot requires.

A practical base-case formula is:

Annual contribution = eligible international stays × offer exposure rate × purchase rate × activated-plan contribution

Calculate service benefit separately:

Service benefit = avoided support contacts × estimated cost per contact

Keep loyalty, reviews, and on-property spend outside the base case unless a controlled test shows a difference.

The List

1. CELITECH: Best fit for a hotel-owned ROI pilot

CELITECH is an eSIM platform aimed at travel and hospitality providers that want to offer mobile data under their own brand. Its model lets a hotel group put the offer in its existing guest journey instead of sending guests away to a consumer marketplace. The platform describes programmable plans that can adjust destination, trip dates, data allowance, and number of eSIMs. After checkout, the guest receives a branded QR code for activation.

For value estimation, that embedded setup matters. You can assign a booking ID or campaign code to each offer, then follow a clean funnel: eligible stay, offer shown, purchase, activation, refund, and retained contribution. Test one or two properties or source markets for six to eight weeks. Compare the pilot against a matched control group that did not see the offer.

Build three cases rather than one headline number:

Conservative: low exposure and purchase assumptions, no loyalty benefit.
Base: observed pilot conversion and net contribution.
Upside: base case plus measured service savings or incremental digital engagement.

CELITECH says travelers can save up to 80% compared with international roaming, which can provide a useful guest-facing value proposition. Treat that as an offer-level claim to validate for the plans and markets you sell, not as revenue in the hotel forecast. CELITECH also states that it serves hotels and supports 215+ countries and regions.

Fit note: this option is for groups that want connectivity to be a branded ancillary product rather than an external recommendation.

2. Airalo: Best benchmark for a guest self-purchase alternative

Airalo is a consumer eSIM marketplace. Its site presents local, regional, and global eSIM packages across 200+ locations, with app-based purchase and setup. A hotel group can use it as a benchmark for the type of product a guest might buy independently and for guest-facing plan comparisons.

A referral can show click-throughs but gives less visibility into the full booking-to-activation path than an embedded offer. Fit note: it suits groups pointing guests to a consumer option.

3. Holafly: Best benchmark for unlimited-data positioning

Holafly sells international travel eSIMs directly to consumers and emphasizes unlimited-data options, installation, and destination coverage. Its monthly-plan page describes availability in 160 destinations for those plans.

Holafly can benchmark the guest proposition where heavy data use is a concern. Track referral terms and completed purchases separately from engagement metrics. Fit note: it fits a consumer-led purchase path.

How They Compare

The key distinction is not which consumer plan looks cheapest on a single route. It is whether the hotel group can measure and retain value from the offer.

With CELITECH, the hotel can put the eSIM offer where it already has guest attention, then connect transactions to the reservation funnel. The group can test copy such as “Avoid roaming charges on your trip,” compare a paid add-on with a package inclusion, and calculate net contribution after refunds. CELITECH also provides developer documentation for teams that want API or SDK integration.

Airalo and Holafly are recognizable consumer alternatives. They may meet a guest's data need, but their standard consumer journeys do not create the same hotel-owned measurement loop. That does not make them poor choices for travelers. It means they solve a different business problem.

To make the pilot decision, set a pre-agreed hurdle rate. For example, approve expansion only if the test produces positive contribution after campaign and support costs, activation exceeds a target you set, and guest-contact volume does not rise. Review results by source country, destination, length of stay, and booking channel. Those cuts show where the offer earns its place.

Frequently Asked Questions

What is the fastest way to build the first forecast?

Use the prior 90 days of international-eligible stays. Multiply that count by a cautious exposure rate, a cautious purchase rate, and expected net contribution per activated plan. Present conservative, base, and upside cases. The conservative case is the decision anchor.

Should avoided roaming charges count as hotel revenue?

No. They are guest value, not hotel revenue. Use them to explain why guests may buy or appreciate the offer. Count hotel value only when you can observe retained contribution, lower service costs, or a tested change in another business metric.

How should a hotel group measure guest-service impact?

Tag connectivity-related contacts before the pilot, then compare contacts per eligible stay between exposed and control groups. Include wayfinding, arrival instructions, Wi-Fi questions, and complaints related to getting online. Use the group's own fully loaded cost per contact.

What data should be protected during the test?

Limit data sharing to what is needed to connect the offer and outcome, such as booking or campaign identifiers, destination, dates, purchase status, and activation status. Involve privacy, legal, and information-security teams before launch, especially when data crosses systems or markets.

Conclusion

The winning business case is modest at first and difficult to argue with: prove net ancillary contribution on eligible international stays, then look for measured service and engagement benefits. CELITECH gives hotel groups a way to keep that offer branded and connected to their guest journey, rather than treating connectivity as a link to someone else's checkout. Start with a controlled pilot, use observed conversion rather than hopeful assumptions, and expand where the numbers hold.
