You get unlimited access to every feature of the Skylink Platform included in the Plan you're trialing for 30 days. Your trial begins once you create your App Key.  You can subscribe to a Plan anytime during your trial or after.  If you don’t choose a plan at the end of the month long trial, you will be downgraded to the post-trial free plan which allows only 10 peer connections per month and does not allow use of either the TURN or SFU/MCU Servers.
