It is not currently possible to change between VPN providers due to business and security reasons. InvizBox units are locked to a VPN provider (either our own VPN or a partner VPN service provider).
We are currently exploring methods where we can securely release provider firmware allowing for provider changes.
Currently, we allow for customers to change VPN providers by shipping the unit back to us, we will update the firmware and mail the unit back to you.
Please contact support@invizbox.com for further details on sending units back for provider firmware changes.
