Your organization's edition determines what features are available to you on the Hologram platform. Hologram offers the Professional Edition and the Maker Edition. To upgrade your organization's edition from Maker to Professional, you simply need to go to the Settings section on the navigation bar in the left side of your screen.
This will take you to the organization's settings page. Where you will find the Active Lines card and on that card the Upgrade to Professional button.
If you don't see the Active Lines card, it means you have not yet chosen your edition. To do this hit the activate SIM button on the top right-hand side of the Devices section.
Hitting the Upgrade to Professional button will open a confirmation page.
Confirming the upgrade will complete the process.
