How to call from the UK00870 or +870, then the number

This is not a country but the Inmarsat satellite network. Calls to +870 numbers are very expensive – do not call back an unknown number with this code.

Missed call from a number starting with +870 – what to do

  • Do not call back an unknown international number. A call that rings once and hangs up (wangiri) is meant to make you call a number with very high charges.
  • Ignore job offers and "easy money" messages from unknown international numbers, for example on WhatsApp.
  • Never read out one-time passcodes, card details or online banking passwords over the phone. Your bank and the police will never ask you to move money to a "safe account".
  • Forward scam texts to 7726 for free and report fraud to Report Fraud, which replaced Action Fraud (in Scotland, to Police Scotland on 101).
