Rocket users do not have the option to switch portals, not for themselves anyway. The option is not there at the Rocket website, while it is an option for nfps and ipotv66 clients.
Only an admin access can change the Rocket portal , unless the code has been purchased from a reseller, then only the reseller can change the portal while the admin can't.
You can switch your code only on the device and not website, is because you have an admin code, yes correct.
