Our position in one line

One telephone line, answered by people with nothing to sell, for guidance and information on anything in this advisory.

§1The line

The advisory is reached on 020 3896 5248.

§2Two minutes of preparation

Have these to hand and a first call settles considerably more.

  • Your postcode, for anything about coverage.
  • Your usage screen or most recent statement, for anything about allowances or billing.
  • The offer in writing, if you want it read properly.
  • Dates and any reference numbers, if it is a complaint.

§3Two safeguards

First: our line reaches this advisory only, never a provider's customer service. For anything specific to your account — a payment, a plan change, a fault on your line — you must use your provider's own official app, website or helpline.

Common pitfallSecond: we will never ask you for a password, a one-time security code, a card number or any other payment detail. Anyone claiming to be from this advisory who does is not from this advisory. End the call.
