3G+ and 3.5G are different names for HSDPA (High Speed Downlink Packet Access), a mobile broadband network standard that delivers faster download speeds, up to 21 Megabits/second. This speed is perfect if you download images, videos or music occasionally, surf the Web or are downloading other large files. 3G+ is part of the Universal Mobile Telecommunications System (UMTS) and a natural evolution for many 3G (third generation) mobile cellular communication systems. More information on the family of GSM network standards is available from the GSM Association.
