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

CSG > Solution > eSIM > Customer Stories > Card1

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.
