class GuestMutation (graphene.Mutation):

    class Arguments:
        name = graphene.String(required=True)
        phone = graphene.Int(required=True)

    guest = graphene.Field(GuestType)

    @classmethod
    def mutate(cls, root,info,name,phone):
        guest = Guest(name=name, phone=phone)
        guest.save()
        return GuestMutation(name=name, phone=phone)

You're returning the wrong information:

class GuestMutation (graphene.Mutation):
    # What you accept as input
    class Arguments:
        name = graphene.String(required=True)
        phone = graphene.Int(required=True)

    # What you return as output
    guest = graphene.Field(GuestType)

So as mentioned, you need to return the guest you created.
