Lauch better eSIM experiences without the usual complexity

CSG EaaS is an additive solution, not a replacement, and it's a differentiator no other platform on the market offers. CSG EaaS supports parallel, dual deployment — it runs right alongside your existing entitlement server. That means you can unlock next-gen capabilities like eSIM Quick Transfer and RCS without disrupting current workflows. No need to rip and replace anything. 

eSIM Quick Transfer replaces the old way of moving a SIM to a new phone — no more downloading apps, scanning QR codes, or waiting on hold. With EaaS, the transfer completes in under 45 seconds, right from the device settings. That means fewer support calls, happier customers, and a device upgrade experience that actually feels like an upgrade. 

This is where Universal Entitlements comes in — and it's exclusive to CSG EaaS. Light MVNOs without AAA infrastructure can access full eSIM entitlements through the MNO's EaaS deployment, without needing to become Apple Carrier Partners themselves. MNOs can expose this as a wholesale product, charging per device and per transaction, creating a net-new revenue stream.

CSG EaaS integrates with billing and settlement capabilities to generate per-MVNO invoices and settlement reports covering all entitlement events and transactions — including eSIM transfers, wearables, and iPad cellular. MNOs can apply differential pricing per MVNO and per use case, with charges tracked at the device and transaction level and invoices distributed on a monthly billing cycle.

CSG EaaS is built on a fully GSMA-compliant platform with ISO 27001-certified infrastructure and regular independent security testing. It eliminates SMS-based activation — a known fraud and cost risk — and uses end-to-end encryption for all provisioning channels. The platform aligns with GSMA SAS accreditation requirements and supports compliance with GDPR and regional telecom regulations.
