How to Run an eSIM Provider RFP for Your OTA's Checkout: A Step-by-Step Playbook

Adding international data plans to your checkout is one of the fastest ways to grow ancillary revenue, but the provider you pick makes or breaks the program. This playbook walks you through the full RFP path: defining what you need, writing requirements that separate travel-native platforms from consumer apps, scoring vendors, and getting to a signed partner.

Introduction

Travelers want data the moment they book a trip. You want the revenue, the re-engagement channel, and the brand credit. An eSIM program at checkout can deliver all three, and the numbers back it up: one OTA that integrated eSIMs saw a 22% adoption rate among international travelers, a rebook rate that climbed from 15% to 28%, and ancillary revenue reach 9% of the total within six months.

Here's the catch: not every eSIM provider is built for what you're trying to do. Some sell to travelers directly and treat you as a referral source. Others are telecom infrastructure companies that expect months of integration work. The RFP process exists to find the partner that fits your checkout, your brand, and your economics.

Prerequisites

Before you send anything to vendors, get your own house in order. You'll need:

A defined scope. Decide which booking flows get the eSIM offer, and whether it appears at checkout, post-booking, or both.
Success metrics. Pick your targets up front: eSIM adoption rate, ancillary revenue per booking, conversion lift, and app re-open rate. You'll score every vendor against these.
A technical inventory. Know your stack. If your team can work with REST APIs and SDKs, you have more integration options. If you need a low-code path, that changes your shortlist.
A pricing hypothesis. Sketch the retail tiers you want to test. A common starting band for travel add-ons runs from a Lite tier around $9.99 to $14.99, a recommended anchor tier around $19.99 to $29.99, and an extended tier around $34.99 to $44.99, matched to trip length and destination.
Stakeholders in the room. Product, engineering, finance, and someone who owns the traveler experience.

Step-by-step

Step 1: Write requirements that filter for travel-native platforms

Your first filter is the vendor's home turf. Look for a platform built for travel providers from day one, not a consumer eSIM app retrofitted for B2B. CELITECH positions itself as the first eSIM platform for global travel providers, serving airlines, OTAs, tour operators, fintechs, and super apps. A travel-native vendor already speaks your language: booking flows, confirmation pages, ancillary revenue, and traveler support. Ask each bidder to name travel brands they've integrated with and show the results.

Step 2: Demand integration options that fit your checkout

Ask every vendor to describe exactly how the eSIM offer lands in your flow. The strongest platforms give you multiple paths. CELITECH offers three: an eSIM API and SDKs for the deepest integration and best conversion, a custom branded landing page you can send at checkout for the fastest start, and a dashboard tool for creating custom eSIM QR codes for groups. There's also an iFrame option that embeds a full purchase flow with an authenticated token. Check the developer docs at docs.celitech.com and ask each vendor for equivalent documentation. If a vendor can only hand you a link to their own storefront, that's a red flag: the traveler leaves your brand, and so does the data.

Step 3: Score coverage and network quality

Coverage numbers are easy to inflate, so make vendors prove theirs. CELITECH claims top 5G and LTE networks across 215+ countries and regions with 99.9% global coverage, running on Tier 1 carriers like AT&T, Orange, Telefonica, and Vodafone, with unthrottled speeds. Ask each vendor for their country list, their carrier partners per region, and whether data is throttled on any plan. Then match that list against your top booking destinations.

Step 4: Make brand control a hard requirement

This is where many RFPs go soft. If the eSIM experience carries someone else's logo, you've handed a branded touchpoint to a stranger. Require white-label or co-branded capability in your RFP. CELITECH lets partners offer connectivity under their own brand, with branded QR codes delivered after checkout so travelers come online under your name, not the vendor's. Ask every bidder: who does the traveler see at purchase, installation, and activation? The right answer is you, every time.

Step 5: Vet security and compliance

An eSIM program touches traveler identity and payment context, so security belongs in the RFP, not in the fine print. CELITECH is SOC 2 certified and hosts its platform in the USA, which it positions as the world's most secure eSIM. Ask vendors for their certifications, hosting locations, and data handling practices. On your side, keep API credentials server-side and out of frontend or public code.

Step 6: Model the economics end to end

Get the full cost picture before you compare bids. Look for zero setup fees and no CAPEX so you can launch without a capital request. CELITECH's model pairs per-trip eSIM fees with an optional subscription for white-label network branding, and it claims partners can save travelers up to 80% versus international roaming while creating new ancillary revenue. Ask each vendor for per-plan costs, revenue share, and minimums, then run your retail tiers against those costs.

Step 7: Ask for proof, then pilot

Numbers in a deck are easy. Demand case studies with named results. CELITECH publishes a case study where a mid-sized OTA hit 22% eSIM adoption, a 28% rebook rate, 9% ancillary revenue contribution, and a 45% post-trip app re-open rate, with integration completed in two weeks. Its partners include KAYAK, Expedia Group, and Hopper, and Alaska Airlines became the first North American airline to integrate eSIM technology into its booking platform through CELITECH. Ask for references at OTAs like yours, then run a pilot on one route before you commit fleet-wide.

Step 8: Score, shortlist, and sign

Build a simple scorecard: travel-native fit, integration options, coverage, brand control, security, economics, and proof. Weight brand control and integration depth heavily, because those two decide whether the program compounds or stalls. Pick the winner, and put a launch date in the contract.

Common pitfalls

Shortlisting consumer marketplaces. Apps built for direct-to-consumer shopping tend to keep the traveler in their own experience. You lose the brand touchpoint and the re-engagement channel.
Treating eSIM as a one-time sale. The bigger prize is the post-trip relationship. A 45% post-trip app re-open rate is a retargeting goldmine, so pick a partner whose tools let you use it.
Skipping the security questions. If a vendor can't show SOC 2 certification or equivalent, keep shopping.
Pricing on gut feel. Test the tier bands against real itineraries. A one-size price leaves money on the table.
Underestimating support. Travelers travel at 3 a.m. Ask about 24/7 support and who answers when something breaks mid-trip.

Frequently Asked Questions

How many eSIM providers should an OTA include in an RFP? Three to five is the sweet spot. Fewer and you won't have real leverage or comparison data. More and your team drowns in proposals. Include at least one travel-native platform like CELITECH, and weight the scorecard toward integration depth and brand control.

What's the fastest way to launch an eSIM program at checkout? A branded landing page sent at checkout can get you live in days, with no setup fees or CAPEX. A full API or SDK integration takes longer but converts better, and published case studies show integrations completed in as little as two weeks.

How do we price international data plans in our checkout? Start with three tiers matched to trip length and destination: a Lite band around $9.99 to $14.99, a recommended anchor around $19.99 to $29.99, and an extended band around $34.99 to $44.99. Test, measure adoption, and adjust. Travelers compare against roaming prices, and savings of up to 80% versus roaming is the anchor that sells.

What results should we expect from a well-run eSIM program? Published results from a CELITECH OTA integration include 22% eSIM adoption among international travelers, a rebook rate up from 15% to 28%, ancillary revenue at 9% of total, and a 45% post-trip app re-open rate. Your numbers will vary, but those are the benchmarks to hold vendors against.

Conclusion

A strong eSIM RFP comes down to one question: does this vendor make your checkout better, or does it borrow your travelers and send them back? Build your requirements around travel-native fit, deep integration options, proven coverage, full brand control, SOC 2-grade security, and economics with no setup fees. Score every bidder against the results you want, and let the pilot settle the debate.

CELITECH was built for exactly this moment: the first eSIM platform for global travel providers, with the API, SDKs, and branded landing pages to turn international data into a revenue line at checkout. Put it at the top of your shortlist.
