Main challenges
Telecom expertise
15+ years running telecom and software projects. We research the market, plan the integration, and assign a named engineer who leads it with your team.
Zero-friction integration
We build and connect your eSIM store or super app, or bridge your existing booking, CRM, or payment system into our platform.
Premium inventory access
Access to non-expiring data, real phone numbers with SMS, unlimited plans, and country-specific rates, whatever your customers need.
Wholesale floor guarantee
We guarantee the lowest wholesale rates and can onboard your current provider if they quoted better prices reselling eSIMs. See your exact numbers with our free ROI calculator.
Flexible integration pricing
API access has no deposit, no setup fee, and no subscription. You pay per sale, so a quiet season costs you nothing.
Management fast-track
Get a ready‑made business case with ROI numbers and security documentation, so internal approval takes days, not months.
How it works
We’ve mapped eSIM integration for hundreds of partners. We help you scope the project and choose the right approach before you commit.
We help you avoid extensive timelines, scaling issues, and other mistakes companies can make.
For bigger projects, we assign a named engineer (a Forward Deployed Engineer) who works with your team directly.
We can help issue refunds for your customers and train your support team.

Everything your customers need is available on the platform: no-expiry data, travel plans, phone numbers, or IoT. Our white-label solutions allow them to stay connected across 150+ countries.
eSIMs
All partners gain access to Keepgo and partner-exclusive solutions:
Lifetime eSIMs
All eSIM bundles currently available on Keepgo (Cygnus, Hydrus, Tucana, etc.). Key feature: the balance depletes only on actual usage.
Travel eSIMs
Available only to partners, these eSIMs offer affordable, country-specific coverage with a fixed validity period.
Unlimited eSIMs
Partner-exclusive eSIMs designed for short-term use (1-7 days). The user receives 1 GB of high-speed data. Once this limit is reached, the connection continues at a reduced speed of 128 Kbps.
Voice & SMS eSIMs
Available only to partners, these digital cards come with an actual phone number, and users can call and send SMS.
pSIMs
If pSIMs are popular in your markets, all esimba.ai partners gain access to our consumer-grade solutions: Lifetime SIMs and Lifetime IoT SIMs. Both run on multiple networks across 150+ countries and offer no-expiry data that's tied to actual usage. The collection is identical to what's offered on Keepgo.
