He told "Table Manners with Jessie Ware": "I don't know if they have GPRS tracking but we did a five-day test to release thing and on the fifth day I left and then they rung and were like "you've left your house'."
Despite this, Sheeran still isn't sure how they knew he'd left the house so quickly.
The "Perfect" hitmaker said: "I don't know whether my neighbours are just ringing up. But I basically got the all-clear on an email just saying, 'You're ready to go' so I left and within half an hour they were like, 'Why have you left?'"
Sheeran also revealed his new phone doesn't even allow him to download social media apps.
In fact, the chart-topping pop star doesn't know the password to his own TikTok account, meaning someone else has to upload his videos to the platform.
Sheeran - who has an 11-month-old daughter called Lyra with his wife Cherry Seaborn - explained: "I don't know the login for my TikTok. People tell me to do this video and then I guess it goes up."
