WhatsApp vs SMS: When to Use Which
Choose the right channel for your message type and audience.
Choosing the Right Channel
Both SMS and WhatsApp have their strengths. Here's when to use each:
Use SMS When:
- You need guaranteed delivery to any phone (smartphones and feature phones)
- Sending OTPs and authentication codes (fastest delivery)
- Your audience includes feature phone users (common in rural Tanzania)
- You want maximum reach — SMS works on every phone
- Sending time-sensitive alerts (delivery sub-3 seconds)
Use WhatsApp When:
- Sending rich media (images, videos, documents, catalogs)
- You need two-way conversations with customers
- Sending longer messages without multi-segment costs
- Your audience is smartphone-heavy (urban markets)
- Running customer support with AI automation
Use Both (Recommended):
The most effective strategy is a multi-channel approach. Use SMS for transactional messages (OTPs, alerts) and WhatsApp for rich marketing content and customer engagement. Sakura supports both from one dashboard.
