Launch your MVNO with a carrier-grade
mobile core — fully integrated with host MNOs. เปิดตัว MVNO ของคุณด้วย Mobile Core
ระดับ Carrier-Grade ที่เชื่อมต่อครบกับ Host MNO

Cipher Telecom is the carrier-grade telecom systems-integration division of Cipher Co., Ltd., a Bangkok-based digital and infrastructure partner founded in 2014 and headquartered in Samut Prakan, Thailand. Where Cipher Co., Ltd.'s main practice covers Martech, marketing automation, and e-commerce platforms, Cipher Telecom focuses exclusively on building, deploying and operating full mobile core networks for Mobile Virtual Network Operators (MVNOs) across APAC.

An MVNO system integrator delivers the full mobile core that sits between a Mobile Virtual Network Operator's business systems (CRM, billing, app, web portal) and its host Mobile Network Operator (MNO). Cipher Telecom delivers five integrated network functions: an Online Charging System (OCS), a Policy and Charging Enforcement Function (PCEF) with Deep Packet Inspection (DPI), a Policy and Charging Rules Function (PCRF / PCF), an SMSC for SMS, and a USSD Gateway — plus the SS7 / SIGTRAN / Diameter signaling required to interconnect with the host MNO.

Cipher Telecom's reference architecture is 3GPP-compliant (Release 17) and covers: Diameter Ro / Gy / Gx for online charging and policy; SIGTRAN over M3UA and SCTP for steady IP-backhauled signaling; SS7 SCCP routing, TCAP transactions, and MAP application layers for legacy interconnect; CAMEL CAP for intelligent voice routing; SMPP v3.4 for external SMS integration; and standard Gi / SGi interfaces with Carrier-Grade NAT (CGNAT) for subscriber egress to the public internet.

For greenfield MVNOs, Cipher Telecom typically goes from contract to commercial launch in 12 to 16 weeks. The phases are: (1) signaling design and Point Code / Global Title allocation with the host MNO, (2) testbed sandbox validation of OCS, PCEF, SMSC and USSD, (3) production routing cutover, and (4) operational handover with telemetry, runbooks and an on-call rotation. This is roughly 60 % faster than a traditional legacy-vendor build because our core is pre-integrated.

Our reference architecture is engineered for 99.999 % (five-nines) availability — equivalent to roughly five minutes of unplanned downtime per year. We achieve this through SCTP and Diameter multihoming across multiple physical interfaces, dual-node A/B clustering for every network element, hypervisor-based virtualization with snapshot recovery, and an active-active operations posture so a single path or node failure does not drop user sessions or billing records.

Yes. Cipher Telecom's Online Charging System (OCS) is convergent: prepaid and postpaid accounts share a single unified database cluster. The OCS speaks Diameter Ro for real-time session charging and CAMEL CAP for voice, which allows precise pre-call balance verification and eliminates the credit-leakage windows common in non-real-time architectures. Product managers can spin up new data tiers, shared family buckets, or application-specific quotas without modifying core system code.

Cipher Telecom's SMSC and USSD Gateway expose modern integration surfaces — RESTful HTTP / JSON APIs and SMPP v3.4 — while translating those calls into the underlying SS7 / MAP signaling required to reach the host MNO. This means an MVNO's web portal, mobile app, or CRM can trigger network services with ordinary developer tooling, without speaking telecom protocols. Each SMS or USSD transaction is also charged in real time via the OCS over Diameter Ro.

Cipher Telecom is headquartered in Samut Prakan, Thailand, and serves MVNOs and enterprise-MVNO programs across APAC, with a focus on Thailand and Southeast Asia. Our typical customers are CTOs, Network Architects, CFOs, Product Managers and Procurement leads at MVNOs, enterprise-mobility resellers, and digital telcos. Engagements run from greenfield core builds to drop-in replacement of legacy charging or signaling stacks.

Traditional telecom vendors typically ship monolithic, proprietary stacks with heavy license costs, long deployment cycles, and tight vendor lock-in. Cipher Telecom takes the opposite posture: virtualized, modular, standards-based network functions delivered as an integrated reference architecture that the MVNO retains operational control over. You get faster time-to-market, predictable OPEX, and the freedom to swap any single element without re-platforming the rest of the core.
