MANILA -- PLDT Inc chairman and CEO Manuel Pangilinan was testing a 5G-enabled Huawei phone and sent out a tweet using an Apple iPhone, according to Twitter posts on Wednesday.

Pangilinan got numerous replies from a Twitter post late Tuesday about testing 5G on a Huawei device, but the post was labeled as sent from Twitter for iPhone.

In separate Twitter posts on Wednesday, Pangilinan and PLDT showed that he was using 2 devices. It was unclear from the posts what type of Huawei phone he was using.

China's Huawei is among PLDT's partners in rolling out 5G in the Philippines.
