Hello CaliKing, that's a really good question. To use the call or text features over Bluetooth, the watch must be connected to a phone through Bluetooth and the Galaxy Wearable app. The watch cannot be connected remotely over Wi-Fi only. Please follow this link https://www.samsung.com/us/mobile/wearables/smartwatches/galaxy-watch-active-40mm-black-sm-r500nzkaxar/?redir=SM-R500NZKAXAR for further specifications on the device. Thank you for reaching out to Samsung. ^Elizabeth
