Robert Colgan, 24, was charged by a team of detectives set up to investigate offences linked to the ongoing flag protests.
Colgan, of Mournebeg Drive, Newtownabbey, is alleged to have had a blast bomb in suspicious circumstances.
The charge relates to the discovery of an explosive device in the Doagh Road area of Newtownabbey on Monday, 4 March.
Colgan also faces six counts of communicating a hoax bomb call to emergency services between Friday, 15 February and Sunday, 3 March.
All of the locations for the alleged false alarms were in the Newtownabbey area.
A further charge of assault on police was put to him as he appeared before Belfast Magistrates' Court.
A detective said he could connect Colgan with the alleged offences. No bail application was made during the brief hearing.
During defence cross-examination, the officer confirmed Colgan is not accused of being in physical possession of the explosives when arrested.
The charge is based on mobile phone use, the court heard.
Colgan was remanded in custody to appear again by video-link in four weeks' time.
