I have registered my son's phone against the mobile app. Recently I purchased a data only plan for my tablet but I can't see a way to add that to the app!
a) Is it possible
b) If so how do I do that

Unfortunately, you cannot add more than one number to the iD Mobile app; you will need to log out of the app and log back in again to access the new account.
I hope this answers your question, just let us know if you need anything else.
