A common UK scam pattern uses blocks like 070 2870 XXXX for 'tech support' calls: a caller claims to be from Microsoft, BT, or your antivirus provider, and tries to get you to install remote-access software. No legitimate UK tech-support team will phone you out of the blue and ask to take control of your computer.
If a 070 2870 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.
