What is rotational churn?(also known as spinning)
• One of your customers gets a new subscription from you
• …and gets rid of the old SIM (and sometimes the phone too)• …without telling you
So this customer appears on your systems as 2 people:
• A leaver• A new joiner

1. Spinning wastes money and resources on: • Welcome packs, welcome calls…• Save / winback,
2. The Churn rate is overstated

5. Valuable customer history data for spinners is lost.

How Idiro Identifies Spinners
Principle 1:• A subscriber may change the phone number
as a spinner, but this would not change his community.
Principle 2:• Social networks are fairly stable over time.• The community is stable over time and
everyone has his unique community.
