XME.digital at MWC Barcelona: 8 FAQs on Generative Customer Portal

---

If you’ve ever built something out of LEGO, you know there are two very different kinds of kits.

One gives you a picture on the box and a fixed set of pieces. You follow the instructions step by step, and in the end you get exactly what was promised. The other gives you a large box of compatible elements. You can build a house today, a bridge tomorrow, and a spaceship next week.

XME.digital was never designed as the first kind.

From the beginning, it was built more like a structured set of interoperable components that can be assembled into different digital services depending on business needs.

Using XME.digital, our team has created a Generative Customer Portal we call Stella#5. It is a customer-facing service that composes UI from governed, preconfigured widgets in response to user requests. We consider it a strong example of the “spaceships” XME.digital enables to create.

Our team is actively investing in the development of Stella#5 as a response to a structural shift in the market.

Service providers are under pressure from both sides. Customers expect digital interaction to feel intuitive and fast, similar to the AI systems they use daily. At the same time, businesses cannot compromise on predictability, integration stability, or regulatory compliance to satisfy this demand.

Bridging those perspectives requires a different underlying model, and Stella#5 is the service that embodies it. We’re going to prove it by showcasing this solution at MWC Barcelona 2026.

Below, we explain what a generative customer portal looks like in practice, how Stella#5 is structured, and what makes this approach different from traditional self-service models.

How is Stella#5 different from a typical AI chatbot?

Standard chatbots limit you to text. Stella#5 delivers a dynamically generated interface and a working dashboard.

The conversation and the UI are a single system. When you type a request, the interface reflects it immediately. More importantly, any action you take within the UI is simultaneously incorporated back into the interaction. 

There’s no separation between a "chat session" and a "UI session." Everything remains fully synchronized and focused on your specific task instead of forcing you to jump between separate tools.

Is Stella#5 another Generative UI builder?

Traditional GenUI builders generate full pages or UI code from scratch. While, enterprises and communication service providers (CSPs) cannot afford interfaces that are generated dynamically without guarantees. You need to be certain about what is presented to your customers. If a system generates entire pages from scratch every time, you lose control over behavior, structure, and quality.

Stella#5 works differently.

It operates with a set of preconfigured, validated, and governed components.

The system relies on predefined widgets that are already tested by real teams on the operator’s side. They have predictable behavior and comply with your quality standards. In this case, the AI doesn't draw a random interface, but intelligently composes controlled elements into a configuration that accurately reflects what the user wants to achieve. 

You can fix parts of the visual interface at the configuration level and apply explicit constraints. Within these boundaries, GenUI adapts and optimizes the experience while you maintain total control and consistency.

How does Stella#5 differ from generic website or cabinet builders?

Generic builders work with abstract blocks like cards and sections. Stella#5 works with telecom-specific entities: offers, services, and their configurations. 

Our widgets have industry expertise embedded directly into their structure. It lets you use built-in domain knowledge instead of recreating it. You reduce implementation time significantly and retain flexibility without sacrificing stability. 

From our end, we provide governed templates which are fully adaptable to specific business scenarios. So, your team doesn't need to design the interface or interaction logic from the ground up.

How does Stella#5 work with legacy systems?

Stella#5 is backend-agnostic. We architected the customer portal as an independent frontend layer that operates across heterogeneous environments. It isn’t tied to any specific backend, so it works seamlessly with your existing CRM, billing, and other operational platforms.

We built an Integration Middleware component directly into the platform. It handles all the heavy lifting: integration, orchestration, and data exchange. Consequently, you can connect the portal to virtually any system without touching the frontend architecture. 

The frontend and middleware are two layers of the same solution. Together, they give you the tools to bridge the gap between modern GenUI and legacy infrastructure without sacrificing stability.

How does Stella#5 work on mobile devices?

We follow a mobile-first approach where it makes practical sense. Smartphone access is the primary usage scenario, so the interface is designed with mobile as the baseline. Meanwhile, mobile interaction patterns are not imposed on scenarios that are inherently desktop-oriented, such as complex B2B workflows or large datasets.

Alongside the responsive web interface, Stella#5 can be deployed as a native mobile application for iOS and Android. The XME.digital team applies a native wrapper to embed the mobile web portal, combining an instantly updated web layer with the experience and capabilities of a native application. 

The underlying domain model and service logic can be exposed beyond the standard Stella#5 interface. Access is provided through APIs, which allow existing mobile applications to integrate directly. You may also build independent channels or custom interfaces on the same functional base as Stella#5. 

The architecture follows a Backend-for-Frontend (BFF) approach, so channel-specific orchestration doesn't require duplication of core business logic. The standard Stella#5 frontend and custom digital channels operate on the same governed backend capabilities.

Are there any limits on interface complexity?

Stella#5 is built to handle complexity. We don’t impose hard limits on how sophisticated your interface can be. In fact, the platform gives your team the freedom to work with core elements at the source code level. Widgets and dashboards can be configured to the extent required by your business.

If you need a completely unique implementation, the platform can expose its internal interaction models. Your team can then build independent interfaces or specialized channels that use the same robust backend as the native Stella#5 frontend. 

We provide the architectural flexibility to scale your vision as far as needed, ensuring your interface remains maintainable and aligned with the platform’s evolution.

What about technical independence?

We designed Stella#5 to eliminate vendor lock-in. If you decide to move on, your customization efforts invested into widgets and configurations aren't lost. Your level of ownership depends on the chosen model.

For service providers seeking full technical independence, we offer private cloud or on-premise deployment. Your team receives full access to the source code of the tailored platform components and all customizations made, ensuring independent extension, modification, and long-term maintenance. You might keep the XME.digital team involved for core platform support.

What changes when you use Stella#5?

Stella#5 shortens the time between a business decision and its execution in customer-facing channels. When you introduce a new service or update an existing one, the change is made once and reflected everywhere. A single rollout makes delivery timelines predictable. Cost savings and clearer release planning come as benefits on top.

Revenue impact comes from immediate commercial reach. New services, upsell mechanics, and partner offers become available to every communication channel simultaneously. 

Questions left?

This is only a fraction of what the generative customer portal can do for your business. Beyond the technology, our focus helps you: 

• Reduce the load on support centers

• Lower the cost of delivering new functionality

• Hit the market with new services faster
