Stephen Brown tried to hide the fact he had a mobile phone which he was using to access social media accounts.
But police discovered a Samsung Galaxy underneath his duvet.
This placed the 41-year-old in breach of his Sexual Harm Prevention Order (SHPO).
Now Brown, of Albert Street, Newcastle, has been sentenced to 10 months in prison at Stoke-on-Trent Crown Court.
Prosecutor Richard McConaghy said a 15-year SHPO was imposed on the defendant in 2017 after he was convicted of attempting to cause a girl under 13 to engage in penetrative sexual activity, making indecent images of children and possession of extreme pornography.
And on September 11 last year he was sentenced to 14 months in prison for four offences of failing to comply with the notification requirements of the sex offenders’ register.
He was released on March 19 and moved to private secure accommodation on March 24. But in April his probation officer noticed he appeared on a WhatsApp list with a photograph of him and a statement that he was now ‘taken and in love’.
Mr McConaghy said: “The same day the probation officer spoke to Mr Brown and he denied having WhatsApp and said it must be associated to an old offence.
“The next day the police attended the accommodation in Newcastle where he was residing. They attended the front desk and saw Brown down a corridor. He turned around and walked away. They went to his room as he said that was where his mobile was. He handed them an iPhone. There was nothing of particular significance on that iPhone.
“He gave permission to search his room. SIM cards were found in a drawer and a Samsung Galaxy was found in the bed under the duvet. It had Snapchat and Skype as accounts on it. It seemed apparent that the data had been recently used on Snapchat and Skype had been used the day before.”
In his police interview Brown said he had been using Skype for about a week to chat to a female. He claimed he would regularly delete parts of their chat. He claimed other apps had been installed on the device but were removed by him.
He admitted the WhatsApp picture was his and he had deleted it after receiving the call from the officer. He added he breached the SHPO because he wanted to remain private and he did not want the police looking at his conversations.
Brown pleaded guilty to three charges of breaching a SHPO.
Arif Hussain, mitigating, said: “He should have had permission if he was to get a second phone and use the internet.
“He simply can’t go on like this, receiving custodial sentences. He understands the sentences are going to get longer and longer.”
Judge Paul Glenn said there was no alternative to an immediate jail sentence. He told Brown: “You were well aware of the terms of the SHPO and you chose to breach them.
“When police conducted an unannounced visit on April 29 they found an internet enabled phone in your bed. You did not notify the police of any installation and use of Snapchat.
“You used Snapchat and Skype. You deleted social media accounts and WhatsApp.
“You told the police you preferred to remain private. You forfeited the right to privacy by offending in the way you did.
“You are still assessed as a high risk of serious harm to children. What your conduct shows is that you are devious and dishonest.”
