Question: What protocol/mechanism is NOT explicitly mentioned as an alternative for data downloading to the SIM, alongside dedicated commands (SMS point-to-point and Cell Broadcast) and the Bearer independent protocol?
Option 1: HTTP (Hypertext Transfer Protocol)
Option 2: Bearer independent protocol
Option 3: SMS point-to-point
Option 4: FTP (File Transfer Protocol)
