Is there any widget to search carrier of the phone number?

Hi, I wonder if there is a widget allowing user to enter phone number, then it will automatically find the corresponding carrier? 

Currently, we do not have any widget which finds the phone number carrier. However, you can integrate your form with third-party APIs.

In order to integrate with third-party APIs, you have to download the form source code and do modification there.

Refer this link to download form's source code:

Let us know if you have any questions.

Thanks.
