Some calls from blocks like 070 857 XXXXX are actually one-ring 'wangiri' calls — the line rings once and disconnects, hoping you'll call back. While wangiri is more common from foreign numbers, UK number-spoofing means 070 857 XXXXX-style ringbacks are not unheard of. Don't return missed calls from unknown numbers without checking them first.
If a 070 857 XXXXX 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.
