The Appeal Court in the UK has halted the deportation of some of the 50 Jamaicans who were slated to be removed from the country on Tuesday.
It ruled that the Jamaicans were not granted adequate access to legal advice ahead of removal.
The court has ordered the Home Office not to deport the Jamaicans unless satisfied that they had access to a functioning SIM card on or before February 3.
The order was granted without a court hearing following an urgent application by charity - Detention Action.
Detention Action argued that some of the detainees at Colnbrooke and Harmondsworth detention centres still do not have a functioning mobile phone, and did not have adequate access to legal advice.
Some of the Jamaicans who were slated for removal have lived in the UK since they were children and viewed their deportation as a repeat of the Windrush scandal during which people who made their lives in Britain were treated as foreigners.
There were also calls for the flight to Jamaica to be delayed until after the publication of a Windrush Lessons Learned report, which will urge ministers to consider ending the practice of deporting people who arrived in the UK as children.
