ZTE's latest MF662 data card supports download and upload rates of up to 21.6Mbps (megabits per second) and 5.76Mbps respectively, the company announced on Monday.
The card is based on HSPA+ (High-Speed Packet Access), also known as Evolved HSPA or HSPA Evolved.
Besides higher speeds, the technology will also allow lower latency -- improving, for example, online gaming performance.
The increased speed will also improve performance on services including mobile TV, downloading music, TV and film clips, and large-volume mail services, ZTE said in a statement.
The card measures 69x27x12mm. Pricing and availability for the card wasn't announced.
Operators including 3 Scandinavia, Telstra in Australia and StarHub in Singapore have all announced plans to launch services.
Vodafone has also expressed interest in the technology and has trialed the HSPA+ on its network in southern Spain and Madrid city center, it said on Monday, but announced no specific launch plans.
