Connectivity
Connectivity options reflect the early 2000s landscape, showcasing GSM network support across bands 850, 900, 1800, and 1900 MHz, thus offering extensive global reach for voice and basic GPRS data services. However, notable absences include Bluetooth and Wi-Fi capabilities, limiting data sharing and internet accessibility. An infrared port extends some connectivity options, useful for transferring data to compatible devices. Meanwhile, a proprietary USB port links the Treo to computers for synchronization and charging.
