RMT server and subscriptions

i am looking for answer if i have to buy Suse subscription to be able to mirror repositories from SUSE Customer Center to RMT local server (Repository Mirroring Tool) if i provision my VMs in AWS or Azure ? I didn’t find direct answer anywhere on website.
Second question is if i use trial subscription (for 90 days period) can enable Support on my account ? i checked solution in FAQ here https://scc.suse.com/docs/userguide#UG-enabling-disabling-support but it doesn’t work. Do i need enterprise subscription instead of trial ?
