Queen Elizabeth allegedly only has two people she phones directly.
The 95-year-old British monarch is said to only telephone her daughter Princess Anne and her horse racing manager John Warren, according to royal expert Jonathan Sacerdoti.
The commentator also claimed the royal has a mobile phone with "anti-hacker encryption by MI6".
Speaking on the 'Royally US' podcast, Jonathan said: "Apparently the Queen has two people who she speaks to the most on her phones and she also apparently has a mobile phone which is said to be Samsung packed with anti-hacker encryption by MI6 so nobody can hack into her phone.
"But the two people she phones the most is said to be her daughter Princess Anne and her racing manager John Warren."
The British journalist also suggested it could be possible rumours are true that Her Majesty has a secret Facebook page because of how good she is with technology, despite her "ripe old age".
Jonathan said: "There've been reports that the Queen has a secret Facebook account, which I can't quite believe [because] she is 95-years-old.
"I have trouble sometimes with new technology, but she seems completely able to pick these things up.
"We saw her during lockdown with all the Zoom calls and the video calls. And now, since her health's been not quite as good as it was in the past, she's been doing more [appearances] that way.
"And now we find out about the Facebook account. It's extraordinary to think how readily and easily she picks up these new technologies ... even at her ripe old age."
Last summer, the queen learned how to video call with the help of her 71-year-old daughter, Anne.
Elizabeth found herself needing to brush up on the latest technology in order to communicate with her loved ones and attend socially distanced royal engagements during the coronavirus pandemic.
On the ITV documentary 'Anne: The Princess Royal at 70', the queen was shown joining a Webex conference to mark Carers Week.
She told those on the call: "Good morning. I'm very glad to have been able to join you."
Anne could then be heard asking her mother: "Can you see everybody? You should have six people on your screen."
The monarch explained to her daughter she could only see four people, but Anne was quick to quip she didn't actually need to see everyone.
She joked with a laugh: "You don't need me. You know what I look like."
