More and more people are using Huawei phones in Ireland, and elsewhere. The company is now the world's second largest phone manufacturer. Yet you'll do well to find a Huawei phone being sold in the US because the company has been blacklisted by Washington, due to fears about spying and national security.
At the same time, American diplomats and lawmakers are pushing other countries to follow the US path. That means your phone could potentially have limitations put on its use, but the impact goes far beyond that.
In this week's 'Explained by Prime Time', Adam Maguire and Mark Coughlan explain why the US is concerned about Huawei, and China's response. And why it leaves countries like Ireland weighing up fears about spies, with the chance to develop key broadband infrastructure and mobile phone networks.
