Mobile Sasa

Mobile Sasa is a Kenya-focused business communications platform for organisations that need to send bulk SMS, run USSD services, manage two-way shortcodes, and message customers on WhatsApp.

Key capabilities include:

• Bulk SMS campaigns with CSV/Excel import, contact groups, message personalisation, scheduling, Unicode support, duplicate detection, live campaign progress, and real-time delivery reports (including DLR callbacks).
• Automated SMS reminders for recurring due dates and scheduled messages (daily, weekly, monthly, annual, and month-end), including per-recipient personalisation.
• Two-way SMS shortcodes (shared or dedicated) with keyword routing, automated responses, webhooks, and competition-style interactions.
• USSD menus and surveys built in a visual editor with a simulator, plus session reports, completion tracking, drop-off visibility, and CSV/Excel export for survey results.
• WhatsApp messaging via the official WhatsApp Business API, using Meta-approved templates, media (images/documents), buttons, and delivered/read receipts.
• Integrations through a REST API (https://docs.mobilesasa.com/) and SMPP access for high-volume systems, with scoped API tokens, role-based permissions, approvals, and audit logs.

Available on Web (portal) and via REST API and SMPP. An Android app is listed on Google Play.

It targets Kenyan organisations such as SACCOs and MFIs, schools, healthcare providers, banks and fintechs, retailers and e-commerce businesses, NGOs, and government teams, plus software companies and resellers.

Notable in Kenya for supporting Safaricom, Airtel, Telkom, and Equitel from one account, offering usage-based pricing with no subscription, and including 10 free SMS on registration. The website also states the platform has been in production since 2015 and is operated by Bitwise Digital Solutions Ltd in Nairobi.
