About 120 workers in Sigma Telecom were laid off this week as the fall out continued from the winding up of the 3G mobile phone retailer.

Sigma Telecom is both a creditor of, and a shareholder in, 3G, which was placed in liquidation last week with the loss of 150 jobs after efforts to attract a new investor to the business failed.

Ulster Bank appointed a receiver to Sigma Telecom at the company’s invitation last Friday.

At that point, there were hopes that the business, which supplied the 3G shops, but also mobile network operator, Meteor, could be saved.

However, Meteor, which was Sigma Telecom’s main business apart from 3G, moved its supply contract to another company, RCI Radius.
