For telecom operators
USSD reaches every handset on your network — smartphone or feature phone, with or without data. Our gateway turns dial codes into interactive, real-time session menus your subscribers and enterprise partners can build on.
USSD (Unstructured Supplementary Service Data) is the session-based protocol behind dial codes like *123#. Unlike SMS, it opens a live, real-time session between the handset and the network — a question-and-answer menu that responds instantly, works on every GSM handset ever made, and needs no internet connection or app.
That reach is why USSD still powers the highest-stakes mobile services: balance inquiries, prepaid recharges, and mobile banking for hundreds of millions of users whose phones — or data plans — can't run apps.
Our gateway sits in your network and turns those sessions into a platform: you (and the banks, utilities and enterprises you partner with) define menu applications, and the gateway handles session state, timeouts, and the messaging that flows beneath.
Session flow
One dial code, one live session — every step round-trips in real time.
- 01
Subscriber dials the code
*123# opens a session — the network routes it to the gateway, which serves the menu application.
- 02
Menu renders instantly
The subscriber sees numbered options; unlike SMS, nothing is stored — it's a live dialogue.
- 03
Selections round-trip
Each keypress goes back to the application, which returns the next screen — balance, confirmation, PIN prompt.
- 04
Session completes
The transaction confirms and the session closes; the gateway logs it for billing and analytics.
Use cases
Session menus that work for every subscriber, not just the ones with data plans.
Balance & validity checks
The single highest-volume self-service query on any network, answered in one screen.
Mobile banking
PIN-protected transfers, deposits and payments — financial inclusion beyond smartphones.
Recharges & packs
Prepaid top-ups and data-pack purchases without a store visit or an app.
Subscriber self-care
Plan changes, offers, complaints and KYC status from any handset.
Surveys & engagement
Interactive polls and campaigns with instant, structured responses.
Enterprise menus
Host menu applications for banks, utilities and government partners on your network.
The platform
USSD looks simple on a handset; running it well at network scale is the hard part we've built for.
Menu application builder
Define flows as configuration — screens, branches, validations and language variants — and update services without code deployments.
Session management
Concurrent-session capacity, timeout handling and state tracking tuned for the burst patterns of promotions and month-end banking.
Integration APIs
Clean HTTP interfaces let banks, utilities and your own systems power menu logic from their backends in real time.
Analytics & audit
Per-service session logs, completion funnels and drop-off analysis — plus the audit trail regulators expect for financial flows.
Comparison
They complement each other: USSD for live dialogues, SMS for messages that should persist.
| USSD | SMS | |
|---|---|---|
| Interaction | Live session — instant menu round-trips | Store-and-forward, one message at a time |
| Persistence | Nothing saved on the handset | Stays in the inbox (receipts, OTPs) |
| Reach | Every GSM handset, no internet | Every handset, no internet |
| Best for | Balance checks, banking, self-care menus | Notifications, OTPs, campaigns |
| Security posture | Session PIN entry, nothing persisted | Message persists — avoid sensitive detail |
