Huawei has stated it is prepared to address any 5G security concerns in South Korea as it continues to court mobile operators worldwide.
South Korean carriers are currently selecting suppliers for their 5G infrastructure. The country’s largest operator, SK Telecom, has already decided against using Huawei, choosing Samsung, Nokia, and Ericsson instead.
Unlike the United States and Australia, the South Korean government has not formally banned Huawei equipment. However, reports that the government is considering restrictions may have influenced SK Telecom’s choice.
“We have complied with each government’s requirements and requests,” Huawei said in a statement. “If the Korean government requests security verification, we will of course cooperate.”
LG Uplus, South Korea’s third-largest mobile operator, has announced plans to deploy Huawei equipment on its 5G network. The operator previously used Huawei for earlier-generation networks, which may help explain its continued business relationship.
Excluding a major vendor from a market often reduces competition and can drive up costs. Analysts estimate that South Korean carriers could face equipment prices 20–30 percent higher if one supplier is barred.
South Korea ranks among the world’s most advanced countries for connectivity, with some of the fastest mobile and broadband speeds. It is expected to be one of the first nations to roll out full 5G networks.
Huawei’s kit is regarded as competitive in performance. Some industry observers say Huawei is leading in areas such as MIMO antenna technology, where the company may be about a year ahead of rivals. Banning its equipment could therefore affect network performance and rollout timelines.
Huawei has been subject to 5G restrictions in Australia and the United States over security concerns and fears of potential influence by the Chinese government. The company has consistently denied these allegations.
If authorities are concerned about equipment sourced from Chinese manufacturers, similar questions have been raised about other vendors. Reports have noted connections between major European suppliers and Chinese entities, which has fed broader debate about supply chain security and governance.
