Multi-IMSI technology selects the optimal network per country in real time. Data billed per MB. Our own global breakouts keep latency low and connections stable.
Each eSIM carries multiple IMSIs. The network stack selects the best-priced, highest-quality carrier per country automatically — no manual configuration.
Global breakout points
Traffic exits our own infrastructure at multiple locations worldwide, minimising hops and keeping latency as low as physically possible.
Per-MB billing
Granular usage-based pricing. No bundle waste, no unused data written off. You pay for exactly what flows through.
API top-up
Add data to any active eSIM in real time via a single API call. Automate top-ups with webhooks on low-balance events.
190+ countries
Global coverage through a single integration. The Multi-IMSI stack handles carrier selection in every market.
No expiry on balance
Unused MB roll over indefinitely. Your customers' data doesn't disappear at midnight or at month-end.

Multi-IMSI technology
Always the right network. Automatically.
A single eSIM holds multiple IMSIs across different carriers and networks. When a device connects, our platform evaluates signal, cost, and latency in real time — and selects the optimal carrier without any action from your application or end user.
No manual carrier configuration
Seamless cross-border handover
Best rate per country, automatically
Single API — all carriers unified
Own global breakouts
Traffic exits close to where it's needed.
We operate our own breakout points at strategic locations across the globe. Instead of routing all traffic back to a single data centre, traffic exits the eSIM.tech network as close to the end user as possible — minimising round-trip time and maximising connection stability.
