The AirCard 503 data card, AirCard USB 308, and AirCard USB 309 modems form the Vancouver company’s second generation of products for HSPA+ networks. The AirCard 503 data card is a convertible 2-in-1 card that fits both PC card and ExpressCard notebook slots. Sierra says its low profile, compact antenna, and impact resistant housing allow it to be safely stored in the notebook card slot even when inactive.

The difference between the two models lies in the HSPA+ frequency bands supported the AirCard USB 308 supports the 850, 1900, and 2100 MHz HSPA+ frequency bands, while the AirCard USB 309 supports the 900 and 2100 MHz frequency bands.
