BEIJING — President Trump can’t use his beloved cellphone while in China, one of the many logistical challenges that he and White House staff faced on the ground in Beijing.

The president, like all travelers to China, was told not to use personal devices in order to protect his data from hackers.

It makes for a tough few days for Trump, who is a frequent phone user — dialing friends, taking calls from reporters, and posting memes.

A White House official confirmed the president wouldn’t be using his personal phone in China.

Posts to his Truth Social account have been limited during the summit — and have likely been posted from Washington, DC, where several White House staff are working Beijing hours to provide logistical support from afar.

The president is not the only one making do without his personal cellular device during this “digital lockdown.”

Administration staffers are using burner phones and burner email addresses during the two-day summit — all part of the White House’s efforts to keep information secure while ensuring the trip flows smoothly.

These devices are stripped of most basic functions and apps to serve as “clean” devices — designed to hold minimal information if breached.

The State Department warns Americans traveling in China that “there is no expectation of privacy on mobile or other networks in China,” and notes many travelers bring electronic devices without personal information.

For White House staff, personal devices were stored on Air Force One in Faraday bags, which block all signals, including GPS, Wi-Fi, Bluetooth and RFID.

The bags protect sensitive data from being hacked remotely.

Trump and his staff will get access to their devices as soon as they board the presidential plane.

Air Force One is considered American territory no matter where it’s parked, and the plane, which functions as a flying Sensitive Compartmented Information Facility, has other ways of protecting data.

Trump has been discussing thorny issues with China’s leader, Xi Jinping, over two days of meetings, including the Iran war, Taiwan, trade and tech.

The two world leaders also built on their personal rapport during a grand welcome ceremony, a state banquet dinner, and even a Chinese band rendition of his favorite campaign song, “YMCA.”
