Network and Connectivity
The NIU Niutek N309 was designed with dual SIM capabilities, allowing users to operate two mini-SIM cards simultaneously. It supported GSM networks across the 850, 900, 1800, and 1900 MHz bands, providing solid coverage for 2G communications. For 3G connectivity, it relied on HSDPA 850/1900 bands, though only on the primary SIM slot. The device offered HSPA speeds of 14.4 Mbps for download and 5.76 Mbps for upload, which was standard for its class during that period.
