For the past year, she was wearing an ankle bracelet to locate her around her father's house.
On Sunday, the ankle bracelet was removed.
Zaghari-Ratcliffe is a convict being held in Iranian prisons for security offenses.
Although Nazanin has had her ankle tag removed on Sunday, she is going to face a new court date for new charges on March 14 due to her activities against the Iranian Establishment.
Zaghari-Ratcliffe was released from jail last March but ordered to remain on the ankle tag at her parents’ home in Tehran.
The UK foreign secretary, Dominic Raab, said, “We welcome the removal of Nazanin Zaghari-Ratcliffe’s ankle tag, but Iran’s continued treatment of her is intolerable. She must be allowed to return to the UK as soon as possible to be reunited with her family.”
He added, “We will continue to do all we can to achieve this. We have relayed to the Iranian authorities in the strongest possible terms that her continued confinement is unacceptable.”
Iranian Intelligence authorities arrested Zaghari at the Imam Khomeini International Airport on April 3, 2016, on her way to London where she has been residing after visiting her parents in Tehran.
The 39-year-old was arrested after it became clear that she had run an illegal course to recruit and train people for the Persian service of the BBC, which is a major party to the "soft war" being waged by the West against Tehran, according to Iranian officials.
Zaghari-Ratcliffe had initially been sentenced to five years in jail on charges relating to national security, but authorities later opened her case and tried her on additional charges based on new evidence including a BBC paycheck and contents of her personal email.
