Hi Dom,

What other ports have been created? I would try configuring wvdial for 
/dev/ttyUSB0 as that is the port assigned for PPP traditionally with 
/dev/ttyUSB2 often used for out-of-band control/signalling. The 
assignment can vary between fw, chipset and device manufacturer.
It is common to block AT commands that don't make sense for a specific 
port. Generally the long form dial command should be more universal.

Use any modem terminal program to connect to the port - if your dial 
command works then you will see the console fill with garbage characters.

For devices that have a more advanced packet type interfaces but still 
offering PPP as legacy support then the PPP interface will be some other 
port like ttyUSB3
I guess you are in Spain or are roaming in the UK with a Spanish SIM?
