Can You Play PS3 Online via Dial-Up? No - Broadband Required

No. The PlayStation Network (PSN) and online games require broadband (DSL, cable, fiber, or satellite). Dial-up is far too slow (56 kbps) for:

• Game data synchronization.
• Voice chat.
• Patch/download delivery.
• Matchmaking latency requirements.

To play online on PS3, you need a broadband connection and a wired or Wi-Fi link to your router. Dial-up only works for offline single-player or local media playback.
