The most trusted communication platform for businesses
One platform.
Every channel.
Endless possibilities.
Fee reminders, loan alerts, OTPs, member polls and campaigns go out from one account. We route each number to its network, and the delivery report comes back the moment the network confirms it. A USSD menu, a shortcode or a WhatsApp template sits in the same dashboard when you need one.
10 free SMS when you sign up, sent under the ready-made MOBILESASA sender name. No card, no contract.

No smartphone needed
Half your customers are on a feature phone
Kenya has more than 60 million active SIM cards and far fewer smartphones. A USSD menu or an SMS survey works on all of them, with no data bundle, no app and no WhatsApp.
USSD: a menu anyone can dial
A customer dials a code such as *544#, your menu appears, and each reply moves them to the next screen. It is a live session over the network itself, so it works on a KSh 500 handset exactly as it does on a flagship, with no internet at all.
Your menu lives at an extension of a shared code, for example *657*YOUR_CODE#. The cheapest way to start; most SMEs, NGOs and pilots begin here.
Cheapest to startA code of your own, for example *777#. Your brand on the dial string, sessions routed straight to you, and the option regulators expect for financial services.
Priced per codeSurveys people answer by texting back
Write the questions once. Push them by SMS to a group, run them on your own shortcode, or hang them on a USSD code. Respondents reply with a number or a few words, and each answer appears in your dashboard as it arrives.

The platform
One portal for the
whole team
Finance tops up the wallet, marketing writes the campaign, a manager approves it, and IT plugs the API in. Everyone works in the same account with the permissions their role needs, while the carrier side stays our problem.
One screen per job
Send, check delivery, top up and pull a report without leaving the portal. Counts update while a campaign is still going out.
Stable on the busy days
Fee-reminder week and end-of-month statement runs are exactly when a platform fails. Ours is built to queue, throttle and keep going when thousands of messages fire at once.
All four Kenyan networks
Safaricom, Airtel, Telkom and Equitel from one account. You send to a number; we work out the network and the route.
Under the hood
What runs when you press Send
Direct carrier binds, a durable queue, and a delivery path we own end to end. The platform was rebuilt from the ground up in 2025 on the lessons of ten years in production.
Multi-carrier routing
Safaricom, Airtel, Telkom and Equitel, each on its own direct connection. Every recipient is routed to their network per message, and when one carrier slows down traffic to the others keeps moving.
Real-time delivery reports
The carrier tells us the handset received it, and we tell you in the same second: in the portal, on the API, and on your delivery callback.
API-first design
Anything you can do in the portal you can do over REST. The /v1/ and /v2/ endpoints are frozen, so an integration written years ago still works unchanged.
SMPP access
Bind your own SMPP client for high volumes: submit and receive delivery reports on one persistent session at the throughput your account allows.
Who may send, who may see
Roles decide who sends, who reads reports and who approves a campaign before it goes out. API tokens are scoped to one integration each, every action is written to an audit log, and the platform is run under the Kenya Data Protection Act 2019.
Reports you can hand to finance
Delivery by network and by sender, USSD completion rates, survey drop-off, and campaign counters that move while it sends. One report per product, any date range, exported to Excel.
One curl command
and you have sent an SMS.
Plain JSON over HTTPS with a Bearer token. Copy the example on the right, swap in your token and a number, and the message is on its way. Code samples for PHP, Python, Node.js and Go are in the docs, and the /v1/ and /v2/ endpoints never change shape, so what you build today keeps working.

}Pricing
Pay only for what you send
No subscription and nothing hidden. The rate drops on its own as your monthly volume grows. Larger organisations can go postpaid and settle at month end.
Each channel is billed separately and only when you use it. Your SMS rate covers SMS; WhatsApp messages are charged at the WhatsApp rates below. Every price on this page includes VAT.
SMS: KES per message
One rate for every network. Delivery reports, the API and the dashboard are included.
Local Kenya SMS, VAT inclusive. A message longer than 160 characters is charged per 160-character part, as the networks bill them.
WhatsApp: KES per message
Billed separately from SMS, at the rate for the template category you send. Replies within an open conversation are free.
A WhatsApp Business number and Meta-approved templates are required; we set both up with you at no extra charge.

What you actually pay
- Is WhatsApp included in the SMS rate?
- No. Each channel meters separately: SMS at the volume rate above, WhatsApp at its per-message rate, USSD and shortcodes at their monthly fees. You are only charged for the channels you use.
- Is VAT included in these prices?
- Yes, everywhere. Per-message SMS rates, registration fees and monthly fees (sender IDs, shortcodes, keywords, USSD) are all shown with VAT already included, so the figure you see is what your wallet is charged.
- Are there setup or monthly platform fees?
- No subscription to use the platform. You pay one-time registration for sender IDs, and monthly fees only for dedicated shortcodes and USSD codes if you take them.
- When does a volume discount apply?
- Automatically, based on what you send in a calendar month. No commitment or negotiation needed to reach the next tier.
Need a custom volume deal, postpaid account, or enterprise USSD pricing?

Who sends through us
SACCOs, schools, golf clubs, insurers, lenders and NGOs. Some send a few hundred messages a month, some send millions, and they all top up the same way.
We send fee balance reminders to 12,000 parents every term. It used to take days. Now it is under an hour and we can see who received it. 🙌

Why Mobile Sasa
Why teams stay
Most of our customers came from another provider. These are the reasons they give for not going back.
We own the delivery path
Direct connections to each carrier, not a reseller of a reseller. When a network slows down we see it on our own dashboards first, and the other networks keep flowing.
Your customers' numbers stay yours
Hashed API tokens, role-scoped permissions, a full audit log, and operations run under the Kenya Data Protection Act 2019. We never sell, share or mine your contact lists.
Every subscriber in the country
Safaricom, Airtel, Telkom and Equitel from one account. If a number is live in Kenya, you can reach it.
An API that does not move under you
Plain REST, predictable response codes, signed delivery webhooks. The v1 and v2 endpoints are frozen, so the integration you wrote in 2019 still runs today.
Ten years in production
Mobile Sasa has been sending since 2015 and was rebuilt from scratch in 2025. Same customers, same numbers, a far faster and more transparent platform underneath.
Every message accounted for
Queued, sent, delivered or failed, with the timestamp, the parts and the cost of each one. If something did not arrive, you can see which message and why.
