GPRS PAP Authentication

[Guest Paraklas]

My GPRS provider requires GPRS PAP authentication in order to work. I literally searched again and again and I can't find it! As far as I know, C500 has Start, Configurations, and there you can select between PAP and CHAP gprs authentication but I can't find it on MPX220 (Rom 1.47).

Any ideas? Perhaps a registry key to change it?

Cheers,
