Telecom & High-Availability VAS Platforms
A decade of operating Value-Added Services infrastructure integrated with Sri Lanka's national telcos. Running messaging at carrier scale teaches a discipline most software teams never develop — and it's the same discipline we apply to every enterprise engagement.
Trusted by Dialog, Mobitel, and Airtel for over a decade.
Capabilities you can engage us on.
High-throughput SMS & messaging
10,000+ SMS/sec peak throughput sustained in production. SMSC, SMPP, and HTTP integrations against Dialog, Mobitel, and Airtel networks.
Subscriber lifecycle & billing
Subscription, renewal, charging, and content-delivery pipelines. Cross-operator billing reconciliation and settlement workflows.
Zero-downtime deployments
Blue-green and canary rollouts, gradual traffic migration, and automated rollback. 99.95% uptime sustained over seven consecutive years.
Observability & incident response
Structured logging, metrics, distributed tracing, and alerting that catches anomalies before subscribers do. Incident runbooks tested quarterly.
Compliance & security
Operating inside national telco networks demands rigorous security and data-handling practices. We operate to that standard everywhere.
Consumer-facing VAS
End-user apps and USSD interfaces riding on the same high-availability backend — proven at national scale.
Principles we don't compromise on.
Assume failure
Every dependency will fail — eventually. Our systems are designed to degrade gracefully rather than cascade, so a single failure becomes a warning, not an outage.
Measure everything
You can't operate at carrier scale without observability. Our platforms are instrumented from the first commit, not retrofitted.
Own the runbook
Seven years of continuous operation means we know how these platforms behave at 3am. We stay operationally engaged past launch.
Tools we reach for.
We're not religious about any single stack. We match the tool to the problem — and we stay current.
A decade operating VAS platforms at national-carrier scale
Dialog · Mobitel · Airtel — A multi-tenant telco application platform powering 20+ consumer services across Sri Lanka's national networks — built, deployed, and continuously operated by Mobisec since 2015.
Building something that has to work at scale?
Whether it's an ERP that can't afford a week of downtime, a consumer app entering a saturated market, or a telco platform that needs to hold five nines — talk to our engineering leadership directly.
