MVNO Core Network replacement
Modernise an existing MVNO core without re-issuing a single SIM. Carrier-grade architecture sized for an MVNO — Active/Standby VMs on the hypervisor of your choice, Master/Slave databases, multi-home SIGTRAN — with a segmented cutover that keeps the dealer portal, the self-care app, and the wholesale agreement with your HNO untouched.
Carrier-grade footprint, MVNO-sized economics
Sized VMs for CC, SBC, SD, API Gateway, OCS, IMS SIG, BSS, and FD — Active/Standby on the critical paths, multi-home SIGTRAN with automatic failover, signalling firewalls per FS.11/FS.19. Run on VMware ESXi, Proxmox, or KVM, on-prem or in your cloud account. No appliances, no forklift refresh.
Subscriber base preserved through cutover
Migration runs in IMSI-range or product-line segments with explicit rollback at every step. Existing IMSIs and MSISDNs carry over; HSS and OCS profiles import in place; CAMEL O-CSI/T-CSI/SMS-CSI parameters move with the subscriber. The dealer portal stays live; the self-care app keeps its sessions.
Replacement that opens new lanes
The same VMs unlock product expansions you couldn't ship on the legacy core: eSIM via GSMA SGP.22 SM-DP+, IoT-grade APN with Gx PCC and Sy spending limits, USSi over IMS so *100# survives the 2G/3G sunset, and a clean evolution into 5G SA on the same hypervisor and the same NOC.
