Just tried to get the above 3G modem working with a vodafone sim on my 2820. I upgraded to the latest firmware yesterday, and it doesn't want to dial.

I can plug it into my PC and it dials OK.

Has anyone else got this combination working?

Here are my settings

PPP Client Mode Enable Disable
SIM PIN code
Modem Initial String APN:internet (Default:AT&FE0V1X1&D2&C1S0=0)
APN Name
Modem Dial String ATDT*99# (Default:ATDT*99#)
PPP Username web (Optional)
PPP Password web (Optional)
