Games organisers had refused on Wednesday to give athletes from Iran and North Korea the Galaxy Note 8 devices from sponsor Samsung, loaded with essential logistical and competition information, due to international sanctions.
Although they backtracked the following day, the incident caused a storm in Iran where Samsung has a major presence.
"Our athletes refused to accept the mobiles and handed in a letter of protest to the Olympic Committee and are awaiting the official and written response," Hassan Taherian, Iran's ambassador to South Korea, told the official IRNA news agency.
IRNA reported that Telecoms Minister Mohammad-Javad Azari Jahromi was looking into the issue, and was considering whether to block imports of Samsung phones.

Shahrokh Shahnazi, secretary general of Iran's National Olympic Committee, told the agency: "The Samsung company and anyone involved in disrespecting Iranian athletes participating in the Pyeongchang Winter Olympics must apologise to Iran's team, and the Islamic republic of Iran will not compromise on this issue."
Although this was not confirmed, the report appeared to trigger a series of "No to Samsung" protests on Twitter.
"If I were a famous person, in response to Samsung's big insult, I would have thrown my Samsung mobile away on camera, and would have asked other famous people to join me," wrote one Twitter user.
Others had a more light-hearted response, with one saying he had slammed the door of his Samsung fridge particularly hard after hearing the news.
