In a move that perfectly captures how artificial intelligence is reshaping telecom, LG Uplus has just made international roaming easier, faster, and smarter than ever before. The company announced on the 19th that it has introduced a Large Language Model (LLM)—the same type of AI that powers modern conversational tools—into its roaming chatbot.

And the results? Impressive. The upgrade has reduced the roaming subscription process from 10 steps to just 4, cutting the time needed from several minutes to under one minute on average.

For frequent travelers, that’s a big deal.

From Rule-Based to AI-Powered Conversations

Until now, LG Uplus’ chatbot worked like most traditional support systems—users clicked through a series of pre-set buttons to get answers or activate roaming. It was functional but far from intuitive.

For example, if you wanted to enable roaming before a trip, you’d have to navigate through 10 manual steps. You’d tap options like “Roaming Services,” then “Plan Activation,” then “Country Selection,” and so on. It worked, but it wasn’t smooth — and definitely not the kind of experience modern users expect.

Now, the upgraded LLM-based chatbot changes that dynamic completely.

Instead of button-based menus, the chatbot understands natural conversation. You can simply type something like:

“I’m going to Da Nang from October 26 to 30. How do I set up roaming?”

In seconds, the AI processes your intent—destination, travel dates, and purpose—and recommends the best roaming plan automatically. Once you confirm the plan and start time, you’re done. No digging through menus. No confusion about data packages. Just a simple chat.

Roaming Setup in Under One Minute

According to LG Uplus, the introduction of the LLM-powered chatbot has cut the average subscription time to under a minute, an achievement that’s already resonating with customers.

Travelers can now handle everything—from plan selection to activation and even cancellation—through a single conversation window.

That’s especially useful when you’re already abroad and suddenly realize you need roaming data or want to change your plan.

What used to take multiple steps and waiting times can now be done instantly, even from a café in Bali or a hotel room in Paris.

The Tech Behind the Magic: Self-Reflective RAG

So how does LG Uplus make this work?

The secret lies in the company’s integration of Self-Reflective Retrieval-Augmented Generation (Self-RAG) technology.

In simple terms, Self-RAG lets the LLM “think twice” before responding. It reviews its own answers, checks for relevance and accuracy, and adjusts based on previous interactions. This self-reflection mechanism ensures the chatbot provides more accurate, context-aware replies, especially for complex questions like data usage limits, international coverage, or plan compatibility.

In other words, the AI isn’t just talking — it’s actually understanding.

A 50-Point Jump in Customer Satisfaction

The impact of this upgrade isn’t just theoretical. LG Uplus reports that since launching the LLM-based roaming chatbot, its Net Promoter Score (NPS) — a measure of customer satisfaction and loyalty — has risen by more than 50 percentage points.

That’s a significant improvement, and it clearly shows that users appreciate the smoother, more conversational experience.

When you consider that roaming is often one of the most confusing aspects of mobile services — with users worrying about hidden costs, data limits, and activation timing — simplifying the process through intelligent chat makes perfect sense.

Why This Matters in the Global Roaming Landscape

Roaming might sound like a small feature, but in today’s connected travel world, it’s a cornerstone of customer experience.

Telecom operators worldwide are racing to simplify roaming through digital-first tools — from eSIM activation to app-based control panels. But most still rely on rigid FAQ bots or manual subscription forms.

By integrating LLMs, LG Uplus is stepping ahead of that curve. It’s not just automating support — it’s personalizing it.

Think about how this could scale:

• Travelers could get automatic recommendations for local roaming packages based on destination and stay length.
• AI could adjust data plans dynamically as usage changes during the trip.
• And future versions could even bundle roaming with travel insurance or Wi-Fi passes, offering an all-in-one travel connectivity service.

It’s a preview of how telecom and travel tech are converging.

Toward a Fully AI-Driven Customer Experience

This upgrade is only the beginning.

According to Seo Namhee, Head of Customer Value at LG Uplus, the company plans to expand LLM integration across all customer service areas, starting with roaming.

“We introduced the LLM to the chatbot to respond more flexibly to complex and diverse customer inquiries,” Seo explained. “We will further develop it into an AI agent capable of natural conversation to deliver a differentiated customer experience.”

That statement hints at a much broader vision — a next-generation customer service ecosystem where AI handles not just routine queries, but even account management, troubleshooting, and plan optimization.

Imagine a telecom service that doesn’t just answer your question, but anticipates your needs. That’s the direction LG Uplus seems to be heading.

What This Means for Travelers

If you’ve ever scrambled to set up roaming before a flight or landed abroad without connectivity, you know how frustrating it can be. LG Uplus’ AI-driven chatbot removes that friction entirely.

The process now feels personal, fast, and natural — just like chatting with a travel-savvy friend who knows all the best data options for your destination.

And since the system can handle plan changes and cancellations, you remain in full control of your costs. No more waiting on hold or navigating through clunky menus.

For business travelers, digital nomads, and vacationers alike, this upgrade marks a major step forward in mobile travel convenience.

The Bigger Picture: AI Is Redefining Roaming

What LG Uplus is doing reflects a growing trend across the telecom world — the AI transformation of roaming.

Operators are realizing that global travelers expect instant, transparent, and adaptive connectivity. The old model of static plans and manual activation doesn’t cut it anymore.

Whether it’s through chatbots like LG Uplus’ LLM assistant or global eSIM platforms that recommend the best data plans automatically, the goal is the same:

Make connectivity as effortless as the journey itself.

Final Thoughts

LG Uplus’ introduction of a large language model into its roaming chatbot isn’t just a tech upgrade — it’s a clear signal of where telecom customer service is heading.

By slashing the process from ten steps to four, reducing activation time to under a minute, and delivering smarter, context-aware answers, LG Uplus is setting a new standard for what “roaming support” should look like in 2025.

AI isn’t replacing human service — it’s enhancing it, making the experience more conversational, efficient, and reliable for travelers who simply want to stay connected without the hassle.

If you travel often or manage mobile services abroad, keep an eye on this development. Because soon, AI-powered roaming assistance may become the global standard — and LG Uplus is already showing what that future looks like.
