Vi turns sacred Kumbh beads into phone-number bracelets — 46% more reunited
At Maha Kumbh 2025, Vi gave pilgrims bracelets of sacred digit-engraved beads spelling a relative's phone number — reunions up 46%.
Vi (Vodafone Idea)
What it had to solve
The Maha Kumbh Mela is the world's largest human gathering: about 500 million people arrived in 2025 and over 5,000 were reported lost each day, many elderly or children without a personal phone.
How it works
The Maha Kumbh Mela is the world's largest human gathering. In 2025 a rare celestial alignment drew an estimated 500 million people to Prayagraj — a temporary city a quarter the size of Manhattan — and more than 5,000 pilgrims were reported lost every day. Many were elderly people or children from rural, low-income families who did not own a phone or could not recall a relative's number.
Vi (Vodafone Idea) noticed that pilgrims already wore sacred Rudraksha and Tulsi bead bracelets as spiritual armour, never removing them even for the holy dip. Ogilvy India turned that ritual object into a product: each bead was engraved with one waterproof digit, and the beads were strung so they spelled a family member's mobile number. If separated, a lost pilgrim only had to show the bracelet to anyone with a phone to be reunited.
The initiative, named Number Rakshak ('guardian'), protected 46% more pilgrims than previous Kumbh Melas. In Uttar Pradesh East — the telecom circle hosting the event — Vi reversed declining brand consideration, cut churn by 2.1%, lifted ARPU 2.5% and grew revenue 3.3%, about $820,000 of incremental revenue. It later won a Grand Clio 2026 in Design – Product Design.
Why it lands
- The beads were already worn by millions and never removed, so the number survived crowds, holy dips and days lost.
- It used the sacred object as the product rather than an ad medium — trust was pre-built and adoption cost nothing.
- It worked for people without phones, solving the real constraint: millions of Indians lack personal mobile devices.
- Success was measured in reunited families and retention, not impressions, so the proof was both human and commercial.
What it did
46% more pilgrims were reunited than at previous Kumbhs; in UP East, consideration turned around, churn fell 2.1%, ARPU rose 2.5% and revenue grew 3.3% (about $820K).
What you can take
Embed the needed utility in a ritual object people already trust and never remove — the medium guarantees adoption, and the outcome (reunited families) sells itself.
Since then
Number Rakshak became one of the most decorated Indian campaigns of the cycle: a Grand Clio 2026 in Design – Product Design (part of Ogilvy's Network of the Year haul), a D&AD archive entry, a London International Awards Bronze and Kyoorius Creative Awards recognition. Vi released a case film documenting real reunions. The brand credited the initiative with reversing a perception decline in its largest telecom circle — churn down 2.1%, ARPU up 2.5%, revenue up 3.3% in UP East — and with reinforcing Vi's role as protector of emotional bonds.
