Pocket Hotspot Pro Netgear M1 - changing network provider?

Hi all

Can anyone help - I've just changed my mobile internet from 02 (60Gb p/m) to Vodafone's unlimited data package.  I thought it would just be a case of putting the new sim into my Netgear and off I go but it's not working.  It recognises there's a Vodafone sim in there but there's no connectivity.  I've tried following the APN setup details on here but, because I can't get that information off the Vodafone sim becasue I can't get it to connect! 

Please send help!

Thanks
