What should I do after a suspicious call from a 0800 number?
Calls to 0800 numbers are free from UK landlines and mobiles.

| 3 | Forward suspicious text messages to 7726, free of charge. |
| 4 | If you lost money or shared details, contact your bank at once and report to Action Fraud (England, Wales and Northern Ireland) or Police Scotland. |
| 5 | For unwanted marketing calls, report to the ICO and block the number on your phone. |
| 6 | Calls to 01 and 02 numbers are charged at your provider’s standard landline rate (gov.uk/call-charges). |
