Why caller ID proves nothing

The facts

Caller ID
Trivially forged
Personal details
Widely traded
Knowing your network
Proves nothing
The only real test
Whether the offer is in the app

What it means for you

Displayed numbers can be faked in seconds, and names, addresses and even plan details circulate freely after data breaches. So a caller who knows all about you has proved precisely nothing.

The genuine test is simple and free: real offers appear inside the network’s own app. If the deal is not there, the call is not real.

Things that are free — and the fees invented around them

The facts

Switching codes
Free
eSIM issue and transfer
Free
Satellite messaging trials
Free
Spend caps
Free
Merger ‘migration’
Does not exist

What it means for you

Free by rule or designThe fee criminals invent
PAC and STAC switching codesAn ‘admin fee’ to release them
eSIM issue, transfer and reissueA ‘transfer service’ or ‘migration charge’
Satellite messaging trialsAn ‘activation fee’
Spend capsAny charge at all
Merger changesA ‘plan migration’ that exists on no network

A demand for money attached to something that is free by regulation is not a warning sign — it is the proof.

One-time codes and number theft

The facts

Genuine staff needing a code read aloud
None, on any network
Purpose of those codes
To stop the person asking
Sudden loss of service
Can mean your number was moved
Action
Ring the fraud line from another phone

What it means for you

No employee of any network, in any situation, needs you to read out a one-time security code. Those codes exist specifically to stop the person who is asking for them.

Watch thisIf your phone loses service for no reason and does not recover, that can indicate your number has been transferred to somebody else’s device. Ring the network’s fraud line immediately from a different telephone — the sooner it is reported, the more can be stopped.

What to do, and in what order

The facts

First, if money moved
Your bank
Second
The network’s fraud team
Third
Action Fraud, for the crime reference
Keep
Every message, number and timestamp

What it means for you

  1. Open the app and look for the offer before responding to anything.
  2. Never agree to anything on a call you did not initiate yourself.
  3. Forward scam texts to 7726, free of charge.
  4. If money has moved: bank first, network fraud team second, Action Fraud third.
  5. Keep every message, number and timestamp — banks and investigators ask for them.
