Deposite money and contact your RM( details can be found in app) to get invitaion link for upgrade to select/wealth banking. Else keep the money for few mobths, bank will contact you for upgrade.
Personally I dont see much benefit doing that (using select banking program) except 2+2 lounge access and movie offer which anyways covered with credit cards. You can evaluate other wealth banking programs for better benefits.
Note: Right now I dont see any RM details in my app, thats another issue. I am in bangalore.
