More than 2,400 Phones 4u staff will lose their jobs after the company announced its closure on September 21, following failed deals with Vodafone and EE.
Administration of the company is being carried out by PwC and will result in 362 of the retailer's stores being closed with immediate effect, costing 1,697 staff their jobs.
Phones 4u, which employed 5,596 people at its height, has retained 720 staff in stores to assist with the closure but PwC said they will then be made redundant once the administration process is complete.
David Jetuah, a spokesman for Phones 4u, told V3 that another 400 members of staff will remain at the company's head office to assist with administration, but that they will also eventually be made redundant.
Dixons Carphone group will take on 824 staff who worked in the 160 Phones 4u concessions located within Dixons and Currys stores.
While Vodafone and EE will save 1,259 jobs by buying 198 stores between them, the rest of the stores are left without prospective buyers. In total 2,417 Phones 4u staff members will be saved from redundancy.
In a statement seen by V3, Rob Hunt, joint administrator and PwC partner, said: "It is with much regret that we have today made the difficult decision to close a large number of stores. It is a very sad day for the staff working at those locations and our thoughts are with them.
"We will make every effort to help the affected staff, working with the Phones 4u HR team over the coming days to support employees," he concluded.
The closure of Phones 4u was due to a lack of business support from major operators. Two weeks prior to the administration procedure, Vodafone withdrew its business from the retailer rapidly followed by EE.
This compounded an already difficult situation for Phones 4u, which had already lost O2 and Three as business partners.
With Phones 4u out of the picture, Dixons Carphone is now the largest independent retailer of network services and mobile phones.
