What is bootstrap?

Bootstrap connectivity is an essential part of eSIM technology. The bootstrap profile comes pre-installed on the device and connects that device to any available network, wherever it is in the world—out of the box.

On demand connectivity

No Wi-Fi? No problem.

Bootstrap is essential to activate devices remotely or where no interface is available. This allows devices to be set up and configured by a central administration, without the need to manually interact with them locally.


Get a global competitive advantage.

Bootstrap provides a more efficient supply chain—enabling device makers to confidently manufacture eSIM enabled devices in a single product line, safe in the knowledge that they will connect anywhere they are deployed.

For Device Makers

More convenient and easy to use.

Users won’t have to insert a SIM card or type in a Wi-Fi password to get their device connected— they are immediately connected to a cellular network from the moment their devices are turned on. Reducing devices’ reliance on Wi-Fi becomes especially important in developing markets where fixed-line connectivity is less prevalent.
