Cubot C21 Connectivity and Performance

Connectivity and Performance

While the Cubot C21 lacks conventional smartphone connectivity features such as WLAN, NFC, and USB, it does come equipped with Bluetooth 5.0 and A2DP, which allows it to connect to other Bluetooth-enabled devices. This feature allows users to sync the device with a smartphone app to track health and fitness metrics. The absence of a SIM card and advanced connectivity features limits its standalone functionality, positioning the C21 primarily as a supplementary device rather than a replacement for traditional smartphones.
