PHONES 4U collapsed into administration on Sunday night after its last remaining mobile operator partner, EE, cut ties with the retailer.
Phones 4U has 720 outlets, including one in Lakeside shopping centre and another in the retail park.
Staff will be briefed by management in stores and at head office on Monday morning.
BC Parters, Phones 4U’s private equity owner, said it is "intended that employees will continue to be paid until further notice".
Mobile industry sources said EE informed Phones 4U of its decision last week.
Phones 4U stores will be closed pending a decision by the administrators on whether they can be reopened for trading. Mobile contracts signed through the retailer will be unaffected.
