LG Uplus said Monday it will jointly promote an artificial intelligence transformation alliance strategy with Amazon Web Services to foster the domestic AI cloud ecosystem.

At Mobile World Congress 2025, held in Barcelona, Spain, the two companies pledged to collaborate on developing a Korea-specific sovereign cloud, AI platforms and solutions, and AI consulting services.

A sovereign cloud is a cloud service that ensures data sovereignty by storing, processing and managing data within a specific country in compliance with its laws and regulations. LG Uplus said that the joint development of a Korea-specific sovereign cloud will enhance data control and autonomy for domestic businesses.

Additionally, LG Uplus and AWS will optimize the telecom carrier’s smaller, telecom-specific language model, ixi-GEN, along with AWS’ large language model, Nova. The two companies will also jointly develop Work Agent, an AI service designed to help companies integrate AI into their operations.

This collaboration will enable Korean businesses, even those lacking AI expertise, to adopt AI services rapidly.

LG Uplus plans to enhance its AI-powered customer service center with an advanced customer agent by integrating AI-based recommendation algorithms and the AWS platform.

Under the agreement, LG Uplus will also join AWS’ generative AI innovation center as a specialized domestic consulting partner. Moving beyond AI partnerships, the company aims to establish itself as a leading consulting partner specializing in sovereign cloud security and data protection.

“Through collaboration with AWS, we will address the pain points of domestic enterprises struggling with AI transformation. We will continue working with global leading partners to strengthen our (AI transformation) capabilities,” said Kwon Yong-hyun, executive vice president and head of corporate devision at LG Uplus.
