The method and apparatus is for providing a mobile station in a telecommunication network with capability of activating a high speed packet data session without subscribing to a high speed packet data service and selecting a higher data rate than the rate it is currently subscribing to. In very general terms the method may have the steps of: activating, by a non high speed packet data subscribing mobile station, a high speed packet data service session with a mobile switching center that is currently operatively connected to the non-subscribing mobile station; allocating, by the mobile switching center, resources for the high speed packet data service session with the non high speed packet data subscribing mobile station; de-allocating, by the mobile switching center, after an end of the high speed packet data service session, the resources for the high speed packet data service session with the non high speed packet data subscribing mobile station; and sending, by the mobile switching center, after an end of the high speed packet data service session, the high speed packet data usage information to the charging system for billing.
