Britain's BT Group will remove Huawei Technologies Co's equipment from its core 4G network within two years, the Financial Times reported on Wednesday.
BT has also excluded Huawei from bidding for contracts to supply equipment for use in its core 5G network, it said.
However, BT will continue to use Huawei's kit in what it considers to be benign parts of the network, such as equipment on masts, FT said.
The Wall Street Journal in November reported that the US government was trying to persuade wireless and Internet providers in allied countries to avoid telecommunications equipment from Huawei. Later, New Zealand rejected Huawei's first 5G bid citing national security risk.
Earlier this year, Australia too banned Huawei from supplying 5G equipment, also citing security risks.
BT and Huawei were not immediately available for comments.
