11 88 00 has suspended its mobile phone directory enquiry service while it’s being improved. It's thought the problem could be caused by the number of people wanting to opt-out; The Telegraph reported that 'thousands' of people were removing their details. A fixed-line directory service is still available from the company. A message on 118800.co.uk says:
The 118 800 service for mobile phone connections is currently unavailable - from this website and by phone - whilst we undertake major developments to our 'Beta Service' to improve the experience for our customers. We'll be back as soon as possible with the new improved service.
All ex-directory requests made by people in our directory to date are being processed. There will be no need to resend these requests. And we will take further ex-directory requests when the service resumes. We will not be taking ex-directory requests by phone or text whilst the service is not operational.
Please do not call us on 118 800 for anything other than landline directory enquiry requests as you will be charged for the call.
Sorry for any inconvenience caused.
