Cost Analysis: Sending 1 Million WhatsApp OTPs vs SMS
By 5MinutesAPI Growth Team•
The Financial Reality of Scale
When your app scales globally, SMS authentication becomes your largest infrastructure expense. Telecom networks in regions like the UK, UAE, and parts of Africa charge upwards of $0.05 to $0.15 per SMS.The WhatsApp Alternative
Meta has heavily subsidized the "Authentication" template category to encourage adoption. Sending a WhatsApp OTP is almost universally cheaper than an international SMS.
The Middleman Tax
If you use a legacy aggregator (like Twilio or Wati) to send 1 Million OTPs to India, the Meta base rate is $0.0014. But aggregators add a markup (often $0.005).
Cost with Aggregator: $0.0064 x 1,000,000 = $6,400.
