eSIM
Launch better eSIM experiences without the usual complexity
eSIM should make life easier for your customers, not harder for your teams. CSG helps MNOs and MVNOs deliver fast, seamless eSIM activation, transfer, and entitlement experiences across iOS and Android.
Turn eSIM into a better customer experience
When activation, transfer and setup work the way they should, you reduce support pressure, speed onboarding and make digital mobile experiences easier to deliver at scale.
Solutions
Support faster launches and smoother eSIM journeys
From activation to device transfer, CSG helps you remove friction from the moments that shape the customer experience and create cost for your business.
Launch eSIM experiences faster across devices
Give customers a faster path to getting started while reducing the complexity your teams need to manage behind the scenes.
Support digital activation journeys across iOS and Android with less effort
Use fast track certification to streamline setup and reduce onboarding friction
Reduce drop-off by making it easier for customers to get connected quickly
Create a more consistent activation experience across devices and customer types
Make moving to a new device feel straightforward
A device upgrade should feel like progress, not a support event. Make eSIM transfer easier for customers and less costly for your teams.
Reduce friction during device changes and upgrade journeys
Cut avoidable care calls linked to failed or confusing transfer steps
Deliver a smoother experience that protects satisfaction at key moments
Support new eSIM features without constant rework
As device makers evolve their entitlement and setup experiences, you need a faster way to keep up without rebuilding your approach every time.
Add support for new OEM-led capabilities more efficiently
Reduce technical drag tied to frequent entitlement updates
Stay ready for change without slowing your roadmap
Scale MNO and MVNO growth from one entitlement layer
Whether you run a direct consumer offer or support partner-led growth, eSIM should help you scale, not add more moving parts.
Support different mobile business models from one entitlement approach
Enable Universal Entitlements to extend eSIM capabilities across broader MVNO scenarios
Use Dual Entitlements to introduce new capabilities alongside existing environments with less disruption
Make it easier to launch and grow digital-first MVNO experiences
Secure entitlement and provisioning flows across the eSIM lifecycle
As eSIM activation, transfer, and entitlement become more tightly integrated with device and network workflows, operators need a platform that reduces exposure across provisioning, authentication, and transaction handling.
Eliminate reliance on SMS-based activation flows that can increase fraud, interception, and operational risk
Support encrypted provisioning and entitlement transactions across device setup, activation, and transfer journeys
Align with GSMA compliance requirements and support secure operations through ISO 27001-certified infrastructure and regular independent security testing
Remove friction, grow faster
Launch eSIM faster with SaaS pricing that scales with growth
CSG helps you reduce upfront cost, accelerate deployment, and support new entitlement use cases with a pay-as-you-grow model.
Why operators are rethinking eSIM entitlements
CSG Entitlements-as-a-Service helps you add next-generation eSIM capabilities without replacing your existing environment, while improving the customer experience and opening new growth options.
No rip and replace
Run CSG EaaS alongside your existing entitlement server so you can introduce new capabilities without disrupting current workflows.
Faster device transfer
Replace manual, support-heavy transfer steps with a quicker, more seamless device-native experience that reduces friction during upgrades.
New MVNO revenue options
Support broader entitlement use cases for MVNOs and create a wholesale service model tied to device and transaction activity.

Customer stories
Revolutionize your customer experience
Before using EaaS, we thought the claim of being the fastest ES solution, with just a 4-6 week timeline, was merely advertising. However, during integration, we quickly realized its simplicity and successfully implemented all APIs in just 2 weeks with only one developer!
Tead of MobileNexphone
Our previous vendor couldn’t meet our timeline or budget. Fortunately, EaaS came to the rescue — not only delivering faster than expected, but also at a much more affordable cost.
