EE customers issued sim card warning which is 'worst of all' An EE sim card warning has been issued after the mobile operator was accused of being "unapologetic" when a customer fell foul to fraud. A customer contacted EE immediately to say they had not requested a new sim after a text from the provider saying one would be activated for them in 24 hours. A customer wrote into the Guardian and said: "EE texted to say they had processed my sim activation request, and the new sim would be active in 24 hours. I was told to contact them if I hadn’t requested this. ‌ "I hadn’t, so I did so immediately. Twenty-four hours later, my mobile stopped working and money was withdrawn from my bank account. With their alien sim, the ­fraudster infiltrated my handset and stole details for every account I had. ‌ READ MORE UK tourists warned 13 items banned from UK even if bought in duty-free "Passwords and logins had been changed for my finance, retail and some social media accounts. Worst of all, two longstanding email accounts are forever irretrievable as the hacker set up their own two-factor authentication, allowing them to halt any password alteration requests, and change my lifelong mobile number. ‌ "I have experienced four weeks of stress and misery, a loss of data and funds, and unfathomable customer relations." In reply,a reader fumed: "The purpose of this 24 hour period is to stop fraud. If JN made contact within this period and the new SIM was still activated then the fault is wholly EE's. "If they proceed within the 24 hours, there is little point in asking for contact within that period if fraud is suspected. The rest of the 'excuse' is just flimflam." Another sniped: "Appalling from EE, doubly so being the most expensive network that apparently prides itself on good customer service. This is verging on negligence. I'd recommend a Subject Access Request and complaint to the ICO as well as EE have been shown to be exceedingly careless in handling personal data." Article continues below Another said: "OK. I'm confused. Very. EE did bugger all with JN's notification & allowed the fraudster to take over her phone. But it still blames JN. So EE was in the position of having two people simultaneously contacting it, one about swapping a SIM card number (unusual!) & another saying they hadn't requested the change. "They didn't follow through with an investigation or halt to proceedings & now blame JN. Shall I throw my phone away? I don't do any banking on my phone but still wonder if some smart shit in his bedroom can somehow access my details & take over & ruin my life."
