What does Masarrati build for mobile & telecommunication?
Masarrati builds telecom and mobile software: BSS and OSS components, charging and billing systems, subscriber self-care portals and apps, MVNO enablement platforms, provisioning and order management, CPaaS messaging and voice APIs, and network and service assurance tooling. Integration work covers TM Forum Open APIs, carrier interfaces and SIM or eSIM lifecycle. Masarrati engineers and hands the platform to your operations team.
Why This Matters
Telecom software is constrained by things outside the codebase: interconnect agreements, regulator obligations, number portability windows and the release cycles of network equipment vendors. A billing change can be blocked by a tariff filing. This is why integration contracts and catalogue-driven design matter more here than framework choice, and why replacements are delivered alongside the incumbent stack rather than as a cutover.
Standards We Build To
- TM Forum Open APIs with the SID and eTOM frameworks for BSS and OSS interoperability
- 3GPP specifications governing mobile network interfaces and service definitions
- GSMA remote SIM provisioning specifications for consumer and machine-to-machine eSIM
- Lawful interception and data retention obligations imposed by national telecom regulators
- Number portability and licensing rules set by regulators such as TRAI in India and the TDRA in the UAE
- PCI DSS where subscriber payment and top-up card data is handled
What We Offer
Capabilities
BSS and Charging Systems
Product catalogue, rating, charging, invoicing and collections built against TM Forum Open API models, so a tariff change is a catalogue entry rather than a code release.
Order and Provisioning Flow
Service orders decompose into network and platform tasks with dependency handling, compensation on failure, and status visible to both the subscriber and the back-office team.
MVNO Enablement Platform
Multi-tenant subscriber management, tariff isolation, wholesale reconciliation against the host network, and branded self-care, so several virtual operators run on one shared platform.
Communication APIs
Programmable messaging, voice and verification APIs with SDKs, webhooks, delivery receipts and per-account rate limiting, built on SIP, SMPP and WebRTC where each protocol fits.
Service Assurance Tooling
Fault, performance and topology data are correlated into service-level views with alarm deduplication and root-cause grouping, giving your network operations staff a workable incident queue.
Subscriber Self-Care Apps
Native and cross-platform apps for balance, plan changes, top-up, roaming controls and eSIM activation, designed to work on constrained networks and older device generations.
Where This Gets Used
- MVNO launch: a subscriber management, charging and self-care stack running on a host operator's network
- Self-care modernisation: a customer portal and mobile app replacing call-centre journeys for plan changes, top-up and billing queries
- CPaaS build: programmable messaging and voice APIs with a developer portal, sandbox keys and usage-based billing
- IoT connectivity: a SIM lifecycle and data-plan management platform for fleet and metering deployments
- Assurance console: a fault and performance correlation tool giving network operations teams service-level incident views
How We Deliver
Domain Discovery
We map products, tariffs, interconnects and regulator obligations before proposing any architecture for the platform
API Contracts
Interfaces are specified against TM Forum Open API models so vendors and internal systems integrate predictably
Parallel Delivery
New components run beside the incumbent stack, taking traffic in stages so subscriber service is never interrupted
Certification and Handover
Interoperability and load testing complete, then documentation, runbooks and source code transfer to your operations team
Common Questions
Frequently Asked Questions
What telecom software solutions does Masarrati build?
BSS/OSS platforms, network management tools, customer portals, billing systems, CPaaS solutions, IoT connectivity platforms, and 5G-enabled applications for telecom operators and MVNOs.
How do you handle real-time communication at scale?
Through WebRTC, SIP trunking, message queues, edge computing, and distributed architectures that handle millions of concurrent connections with sub-100ms latency for voice, video, and messaging.
Can you build CPaaS or communication APIs?
Yes. Masarrati builds programmable voice, SMS, video, and chat APIs with developer-friendly SDKs, webhooks, real-time events, and global carrier connectivity for businesses building communication features.
What mobile app development approaches do you use?
Native (Swift/Kotlin), cross-platform (React Native/Flutter), and progressive web apps. Choice depends on performance needs, platform features required, budget, and time-to-market goals.
How do you ensure mobile app performance?
Through efficient rendering, lazy loading, offline-first architecture, image optimization, background task management, memory profiling, and continuous performance monitoring in production.
What is BSS/OSS modernisation and how is it delivered without downtime?
Business support systems handle product, order, billing and customer care; operational support systems handle inventory, activation and assurance. Modernisation replaces components rather than the whole stack. We put an API layer over the incumbent system, move one domain at a time, and run both in parallel with reconciliation until the new component is authoritative. Subscribers keep service throughout, and each step can be reversed.
Can you build the software stack for launching an MVNO?
Yes. A typical build covers subscriber and SIM lifecycle management, product catalogue and rating, charging and invoicing, self-care web and mobile applications, and reconciliation against the host operator's wholesale records. Integration to the host network follows the interfaces that operator exposes, and eSIM activation follows GSMA remote provisioning specifications. Masarrati builds and hands over the platform; commercial operation and regulatory filing remain with you.
How do you approach telecom billing accuracy and revenue assurance?
By making the charging path auditable. Every rated event keeps its input record, the tariff version applied and the resulting charge, so any invoice line can be traced back to source. We build reconciliation jobs comparing network usage records, mediation output and billed amounts, with discrepancies raised as cases for your revenue assurance team. Tariff changes are versioned and testable against replayed traffic before release.
What are TM Forum Open APIs and why do you build to them?
They are a standard set of REST interfaces and data models covering product catalogue, ordering, billing, customer and service inventory, published by TM Forum and widely adopted by operators and vendors. Building to them means a new component can integrate with existing systems without a bespoke interface for each, procurement can compare vendors on the same terms, and your team can replace a module later without renegotiating every integration.
