Does Zipya use my Mobile Data for file transfer?
No. Zapya does not require nor depend on WiFi-based Wireless Local Area Network (WLAN). Users can share files without mobile data service nor SIM card. Zapya uses direct wireless connection between devices and thus incurs no mobile data traffic during file transfer. If you choose to share files via Wi-Fi, the files will be copied over in your local network without uploading to a middle server; if you follow above instructions to send files through Wi-Fi hotspot, the files will be shared peer-to-peer directly. You don’t have to turn on Mobile Data on the phone before you can enable personal hotspot on Android phone. Make sure to disable Airplane mode though. Otherwise, you can’t activate mobile hotspot on the phone.
