Connectivity became the highest-engagement feature.
Lumen serves 4.8M cross-border banking customers across 38 markets — migrants, freelancers, expats, students. Their highest-churn segment was users who left their primary market, where local banking apps offered cheaper data and stickier rewards. Embedded connectivity changed that calculus inside 30 days.
Lumen's value proposition was simple: one banking app for users who lived across multiple markets. The hidden problem was that 'one banking app' didn't help if the user's data plan died at the border. A migrant worker landing in a new market needed a SIM before they needed banking — and the local SIM came with a local app, a local rewards program, a local relationship.
User research showed 41% of cross-border churn happened in the first 30 days after a market move. Cheaper local apps with bundled data offers were peeling Lumen users off at the airport, on day one.
The product team had explored partnerships with eSIM providers, but every conversation ended with a 'too narrow geography' or a 'six-month enterprise contract' that didn't match Lumen's velocity. The CTO's view: 'We need to ship this in a sprint, not a fiscal year.'
Lumen's compliance team had a non-negotiable: connectivity could not pull customer KYC data into a separate audit boundary. Next IVA's eKYC integrates directly with the eSIM provisioning flow, so identity verification for connectivity uses Lumen's existing customer record, with one audit chain end to end.
Implementation took four weeks, with one of those spent in compliance review. The integration sits cleanly outside PCI scope — connectivity provisioning never touches card data — and the data residency controls let Lumen pin EU customers to EU infrastructure without custom plumbing.
The user experience: a customer opens the app, taps 'Add data plan,' picks a region, and an eSIM lands on their device in 178ms. No new KYC. No new app. No new relationship. Just connectivity, where their banking already lives.
Within 30 days of launch, embedded connectivity was the most-tapped feature in Lumen's app. Within 60 days, it was the strongest predictor of 90-day retention in their entire user model.
Embedded data became our highest-engagement feature within 60 days. The compliance integration was the cleanest telecom partnership we've shipped.
