What is CSGO Prime Account?

Prime Accounts were first introduced by Valve in April 2016 for improving the matchmaking system. Counterstrike Global Offensive Player has to add their mobile number to enable the Prime Account Status.
After 6th Dec 2019, there was an update in Counter-Strike Global Offensive which states that if you bought the Counterstrike Global Offensive before the update then you will have Prime activated on your account & if you haven’t purchased Counterstrike Global Offensive then you can play it for free but you won’t get the Prime Account Staus. You can still buy the Prime Account Status on Steam for $14.99 or play until you reach Private rank level 21 or else we can say Lieutenant Level 21.
