VoWiFi Has A Proven Business Case

Prepaid subscribers with p

month, and therefore top up le

By solving the indoor coverage challenge, VoWiFi dramatically

increases the CLV of 10–20%+ of your subscribers

The Customer Lifetime Value (CLV) of subscribers with poohome coverage is signi ficantly lower than average

Postpaid subscribers with poor home

coverage either cancel their service right

away or churn early in their lifecycle
