This is a long shot: BUT I responded to a deal here last week for a refurb mobile phone from Sainsburys Phones. I recieved the phone which should have been unlocked to find it was locked. I phoned their customer service who said they have a problem with a batch of phones for Black Friday week. Basically they don't know what network these phones are locked to !!! SO - customers can't get the cheap unlock codes to make them work on any network. My phone is a Motorola Moto E (2nd Gen) Anyone out there who knows what network they are locked to, or how to help? The phone looks brand new !!
