The Hologram Nova is a cellular modem purpose-built for global IoT development with single board computer compatibility and Hologram software tools. For more information about the Nova, please refer to this page.
Hologram SIMs and Nova hardware are made for connection to our cellular network with zero configuration. However, using a third party SIM is possible. To do so, you would need to modify the APN to your SIM's APN on our SDK's chatscript or through AT Commands. The chat script is available here.
