This information will be updated if the surcharge is implemented by additional providers.

Affected call types

The following call types made to UK Mobile numbers may be charged at a surcharge:

Calls made from an international phone number from a country in the surcharge list: These calls will be charged with new surcharge billable items in place of standard "UK Mobile" billable items.

Notice: If you place calls from the UK, EU, United States & Canada, or from another country with no surcharge, then there is no change. See the list below for surchage countries.

Calls made with modified, missing, invalid, incorrectly formatted, or Anonymous caller-IDs: These may include the following type of calls:

  • Any call with anonymous as the calling number
  • UK numbers (+44) that are invalid numbers.
  • Any calls having an international calling number with an incorrect format.
  • Any calls with dummy calling numbers, including the use of usernames as the CLI.

How can I identify surcharges?

Surcharge pricing can be identified by the following billable Items:

  • Programmable Outbound Minute - United Kingdom - Mobile - from SurchargeZone1
  • Programmable Outbound Minute - United Kingdom - Mobile - from SurchargeZone2
  • Trunking Outbound Minute - United Kingdom - Mobile - from SurchargeZone1
  • Trunking Outbound Minute - United Kingdom - Mobile - from SurchargeZone2

What do I need to do?

To avoid your calls being billed at a surcharge, we recommend the following actions:

  • Ensure that your calls comply with the Caller-ID restrictions mentioned above.
  • Use an outbound From number for making these calls that is based in a country with no surcharge like UK, EU, US, Canada, etc. For help finding a phone number from a no surchage country, see How to Search for and Buy a Twilio Phone Number from Console.
