Powerful channels
Reach customers who don't have smartphones
Kenya has 60M+ active SIM cards but far fewer smartphones. USSD and SMS surveys reach everyone — no data, no app, no WhatsApp needed.
USSD — interactive menus on any phone
USSD sessions are real-time, session-based conversations triggered by a dial code — think *544# on Safaricom. No internet, no smartphone, no app required. Works on a KSh 500 feature phone just as well as a flagship device.
Your menu lives under a shared shortcode (e.g. *384*YOUR_CODE#). Lowest cost to get started — ideal for SMEs, NGOs, and pilots.
From KES 2,000/moYour own shortcode (e.g. *777#). Full branding, faster session routing, and no keyword conflicts. Required for financial services.
Custom pricingMobile surveys — SMS, USSD, or simulator
Build surveys once, reach respondents through any channel — outbound SMS, a USSD dial code, or the built-in simulator. No app, no link, no data connection required. Responses stream into your dashboard in real time.
- 1Build your survey in the portal — branch logic, skip patterns, free text
- 2Send via outbound SMS to your contacts list or CSV upload
- 3Or attach to a USSD extension — respondents dial *657*XX# on any phone

The platform
Manage all communication
under one roof
MobileSasa gives you a clean, well-organised portal with everything you need to broadcast messages across any channel. We handle the carrier complexity — you just focus on reaching your customers.
Well organised interface
Everything your organisation needs under one umbrella. Insights are real-time. Send, track, and report without switching tools.
Engineered for reliability
Our team works continuously to ensure the platform stays stable under load — including campaign days when thousands of messages fire at once.
All four Kenyan networks
Safaricom, Airtel, Telkom, and Equitel — every network, one account. Messages route to the correct carrier automatically.
Infrastructure
Built different. Built for scale.
Under the hood, MobileSasa is engineered for reliability — not retrofitted from legacy infrastructure.
Multi-carrier routing
All four Kenyan networks — Safaricom, Airtel, Telkom, and Equitel. Messages route to the right carrier per recipient automatically. When one carrier degrades, traffic shifts without you doing anything.
Real-time delivery reports
Delivery status pushed the moment the carrier confirms — not polled every 30 seconds. Your DLR callback fires within seconds of actual delivery.
API-first design
Every feature available via REST API. Legacy /v1/ and /v2/ endpoints preserved for existing integrations — zero migration required.
SMPP access
Persistent SMPP sessions for high-throughput workloads. Bind your own client, submit and receive delivery reports on the same session at full carrier throughput.
Enterprise-grade access control
Role-based permissions — who can send, who can view reports, who approves campaigns. Manager approval workflows for high-risk sends, scoped API tokens, audit logs, JWT auth, and Kenya Data Protection Act 2019 compliance.
Unified analytics
SMS delivery by carrier and source, USSD session completion rates, survey drop-off by channel, campaign counters live while sending. Dedicated reports per product, exportable by date range.
Your first message
in under 5 minutes.
One HTTP call. Plain JSON. Bearer token auth. No SDK required — though we have libraries for PHP, Python, Node.js, and Go if you want them. Legacy /v1/ and /v2/ endpoints stay frozen — existing integrations never break.

Why MobileSasa
Built by people who've felt the pain
Every feature exists because a real Kenyan business needed it. Ten years of customer feedback shaped every decision.
No compromise on delivery
Direct carrier integrations mean we own the full delivery path. When a carrier degrades, we know before you do — and traffic shifts automatically.
Security & compliance
JWT auth, hashed API tokens, scoped permissions, full audit logs, and Kenya Data Protection Act 2019 compliance. Your data and your customers' data stays yours.
Every Kenyan subscriber
All four Kenyan networks — Safaricom, Airtel, Telkom, and Equitel. Every subscriber in Kenya is reachable from a single MobileSasa account.
Developer-first API
Clean REST API. Predictable response codes. UUIDs everywhere. DLR webhooks. Legacy v1/v2 endpoints frozen — existing integrations never break.
10 years, continuously improving
MobileSasa has been in production since 2015. The platform is rebuilt ground-up for 2025 — same proven reliability, modern engineering underneath.
Transparent reporting
Every message tracked from queue to delivery receipt. Cost, parts, DLR status, and timestamps visible in real time. No black boxes.
