Embedded connectivity for products that ship globally

Embedded connectivity means cellular built into your product, not bolted on. Firsty makes that one integration, data, voice, eSIM, and numbers across 200+ countries through a single API.

Cellular, built in

Devices that work anywhere on unboxing

No SIM logistics for the buyer.

Apps that provision data in-flow

No carrier handoff, user never leaves.

One connection layer you control

Not a patchwork of operator portals.

Coverage that follows the user

A single-operator SIM cannot promise coverage wherever the user is. Firsty routes across many networks per session, so coverage follows the user. If a network relationship changes, we swap the IMSI over the air, no recall, no user action.

Where teams embed Firsty

  • IoT and devices
  • Travel apps
  • Fintech and identity
  • Phone numbers
  • AI agents

From one test SIM to a global fleet

Start with a free sandbox and one test SIM. Scale to a global fleet on the same API. One global rate, so unit economics hold across borders.

No card for the sandbox
