WhatsApp is hugely popular in Kenya, so many businesses ask whether they still need SMS. The honest answer: they do different jobs well. Here’s how to choose.
Reach
SMS works on every mobile phone — feature phones included — with no app, data bundle or internet connection. WhatsApp only reaches customers with a smartphone, the app installed and data available at that moment. For messages that must reach everyone, SMS wins.
Reliability for critical messages
For OTPs, payment alerts and security notices, SMS is the dependable default because it doesn’t depend on data. Many businesses send OTPs via SMS and fall back to voice when needed.
Rich content and conversations
WhatsApp supports images, documents, buttons and long conversations, which suits customer service, catalogues and order tracking for smartphone users. SMS is text-only and short, though two-way SMS handles simple replies well.
Cost
SMS is priced per message part, so cost is predictable — see SMS pricing. WhatsApp Business Platform charges per conversation by category, and marketing conversations can cost more than a single SMS.
Marketing rules
Both channels need opt-in consent for promotions under Kenya’s Data Protection Act. WhatsApp also enforces its own template approval and quality rating, which can restrict accounts that get reported.
Quick guide
- Use SMS for: OTPs, payment confirmations, reminders, alerts, and any message that must reach everyone.
- Use WhatsApp for: rich support conversations and product catalogues for smartphone users.
- Use both: SMS as the guaranteed baseline, WhatsApp as an extra channel.
