Calls from 01606 89 XXXX numbers that ask you to 'press 1' or to call back a different number should be treated with caution. This is a classic premium-rate trap — the call-back number is often in the 09xx range and costs several pounds per minute. Never call back an unfamiliar number you've been instructed to dial.
If a 01606 89 XXXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
