British corporal sentenced after phone hack follows ignored SIM card order

Daniel Barton-Kennedy, a British corporal, was sentenced to 10 months in detention for disobeying a direct order to remove the SIM card from his cellphone. The sentence was handed down after he pleaded guilty to defying a lawful command during a military deployment.

The incident began in January when Barton-Kennedy’s unit, the 1st Battalion of the Duke of Lancaster Regiment, was briefed on security protocols before leaving for Estonia. He had served in the army for more than seven years at the time. Commanders instructed all personnel to remove SIM cards, turn off location settings, and use a trusted virtual private network on personal devices.

The unit traveled to Tapa, Estonia, to participate in Exercise Eastern Warrior. Tapa is located roughly 90 miles west of the Russian border. After arriving in the country, soldiers received additional briefings reiterating the same digital security rules. Barton-Kennedy kept his SIM card in the phone despite these repeated warnings.

Court records indicate that the failure to follow protocol left the device vulnerable. The phone was hacked, and nude photographs of Barton-Kennedy were stolen from the storage. The stolen images were subsequently used to blackmail the soldier.

The case was initially reported by the Estonian newspaper Eesti Ekspress, which obtained a 21-page appeals court document. The document details the sequence of events and the disciplinary action taken against the corporal. He was reduced in rank as part of the punishment.

The deployment area in Estonia is situated halfway between Tallinn and the border with Russia. The proximity to adversarial territory added a layer of risk to the operational security breach. The court document confirms that the specific instruction to remove the SIM card was part of a standard briefing on January 7.

Barton-Kennedy’s guilty plea concluded the court-martial process. The 10-month detention sentence is now part of his military record. The case highlights the specific consequences of ignoring digital hygiene directives in a high-risk environment.
