Yes this should be possible, but to make sure please send us an email at email@example.com as sensitive details we'll need to be exchanged. (I.e. your personal number and your HulloMail Voicemail number).
HI Robert Patey,
To get the Pro subscription, all you have to do is open the Hullomail app, then go to Menu > In-App Store, then subscribe to either the Pro Monthly or Pro Yearly plan.
Can I divert apart from my mobile, my DDI to my hullomail?
I just find it so easy to pick up messages from my mobile on the app.
If so, what will be the number and do I need to set up any other changes?
