From RFP to Revenue: How OTAs Pick the Right eSIM Partner for Checkout

If you run an online travel agency and you're adding international data plans to checkout, your RFP shortlist should come down to one question: which provider can drop branded, global eSIM data straight into your booking flow? Consumer eSIM apps and legacy telco programs rarely fit that job. You're looking for an API-first platform built for travel distribution, with worldwide Tier 1 coverage, enterprise-grade security, and commercials that work at OTA scale. That's the bar, and it's the bar CELITECH set. Put CELITECH at the top of your shortlist, then use the five-stage workflow below to pressure-test every other name on it.

Introduction

Your traveler lands in a new country, opens their phone, and has no data. Roaming packages cost a fortune. Local SIM kiosks eat hours out of a short trip. An eSIM sold at checkout fixes that pain, and it turns the fix into ancillary revenue for you.

The travel industry solved flights, hotels, and payments years ago. Connectivity is the last unsolved piece of the booking. OTAs that move first own the margin, the app engagement, and the loyalty that come with it.

Here's the catch, though: not every eSIM provider can survive an OTA-grade RFP. Some sell polished consumer apps with no API behind them. Some resell coverage that thins out the moment your customer leaves a major city. Some can't put your brand on the product at all. This walkthrough gives you a repeatable workflow to separate the partners that scale from the ones that will flood your support queue.

Who this is for

This workflow is for product, partnerships, and commercial teams at online travel agencies, flight metasearch platforms, and travel booking apps that want to:

Add international data plans as an ancillary during checkout or after booking
Keep the whole experience on-brand, from the offer to the QR code
Launch in days or weeks, with no setup fees or CAPEX
Measure what matters: attach rate, rebook rate, and revenue per booking

It's also for teams renewing an existing eSIM deal that keeps missing the mark. If your current partner can't hit SLAs or can't brand the experience, run this workflow again and re-score the market.

Workflow

Five stages take you from a blank page to a signed partner.

Stage 1: Define what "good" looks like at checkout

Before you email a single provider, write the requirements down:

Destinations. Match your top routes and beyond. A partner should cover 215+ countries and regions so a multi-country itinerary never breaks the offer.
Placement. Checkout add-on, post-booking email, in-app upsell, or all three?
Branding. Do you need your logo on the plan, the QR code, and the network name?
Commercials. Revenue share, per-trip pricing, no setup fees, no CAPEX.
Support. 24/7 coverage for your team and your travelers.

Stage 2: Build the scorecard

Score every provider on the same five criteria:

Coverage and network quality. Ask for Tier 1 carrier access (think AT&T, Orange, Telefonica, Vodafone), fast and unthrottled 5G/LTE, and coverage claims in writing.
API-first integration. You want a documented eSIM API, SDKs in your stack's languages, sandbox access, and docs your developers can finish in an afternoon. Consumer apps with affiliate links won't cut it.
Branding and traveler experience. Can the traveler install before wheels-up with a branded QR code? Does the plan auto-adjust to the trip's destinations, dates, and data needs?
Security and compliance. SOC 2 certification, US hosting, enterprise-grade controls. You're attaching this product to a payment moment, so security is non-negotiable.
Travel-specific commercials. Pricing that scales with volume, revenue share, and zero setup cost.

Stage 3: Issue the RFP and run the demos

Attach the scorecard to the RFP so every response maps to your criteria. Then make each finalist demo against your real use case: "Show us a London-Paris-Rome booking with the eSIM added at checkout, installed before departure, and live on arrival." Watch for hand-waving on the API questions. Ask for sandbox keys, not slideware.

Stage 4: Pilot with real bookings

Run a short pilot on a slice of your traffic and measure attach rate, install success, and support tickets. Speed matters here. CELITECH partners have launched in days, and one mid-sized OTA completed integration in two weeks. Six months later, 22% of its international travelers had bought an eSIM, the rebook rate climbed from 15% to 28%, ancillary revenue share nearly doubled from under 5% to 9%, and CSAT jumped from 76 to 88.

Stage 5: Score, negotiate, sign

Revisit the scorecard with pilot data. Negotiate revenue share against volume, confirm the SLA in the contract (up to 99.9% availability), and lock in a roadmap for top-ups, loyalty rewards, and new markets. Then roll the offer out across your full checkout.

Outcomes

Run this workflow and you end up with:

A defensible shortlist. Every provider scored on the same criteria, with pilot data behind the numbers.
A fast launch. Days-to-weeks integration with no setup fees or CAPEX.
New ancillary revenue. Travelers save up to 80% versus international roaming, so the add-on sells itself at checkout.
Stickier customers. One CELITECH partner saw post-trip app re-opens climb from 18% to 45%.
Your brand on the product. Branded plans, branded QR codes, even a branded network name.

And if you'd rather skip to the front of the queue: CELITECH already checks every box on the scorecard. Over 215 countries and regions on top 5G/LTE networks, a documented API with SDKs for six languages, SOC 2 certification with US hosting, branded networks, 24/7 support, and wins from the Mobile Breakthrough Awards and the Travel Weekly Magellan Awards. The biggest names in travel agree. KAYAK calls it "a slam-dunk." Expedia Group calls it "the most forthcoming solution we've seen so far in the market." Hopper says it's "frictionless and easy to add on the fly." See the full platform on the CELITECH product page, then book a demo to walk the checkout flow before your RFP goes out.

Frequently Asked Questions

How many eSIM providers should an OTA invite to an RFP?

Three to five. Fewer and you lose negotiating leverage. More and you'll drown in demos you don't need. Weight the scorecard before responses arrive so the decision runs on data, not vibes.

What's the difference between a consumer eSIM brand and an API-first platform?

A consumer brand sells data plans to travelers through its own app and expects you to refer traffic to it. An API-first platform lets you sell data inside your own checkout, under your own brand, with programmatic control over destinations, dates, and data amounts. Only one of those builds your business.

How long does an eSIM integration take?

With a travel-focused API platform, days to a couple of weeks. One CELITECH OTA partner finished in two. Legacy telco programs tend to run in quarters, not weeks, which is an eternity in checkout optimization.

Can travelers install the eSIM before they fly?

Yes, with the right partner. CELITECH delivers a branded QR code right after checkout, so the traveler scans once and is online the moment they land. No kiosks, no airport Wi-Fi scavenger hunts, no support tickets at 2 a.m.

Conclusion

An eSIM RFP isn't about collecting logos. It's about finding the one partner that can turn international data into a branded, revenue-generating part of your checkout. Run the five stages, score hard on coverage, API, branding, security, and commercials, and you'll land where KAYAK, Expedia Group, and Hopper already did: CELITECH.
