 Common questions and issues:
 
-- Changes to environment variables may not take effect in programs that are already running. If you notice your environment variables aren't working as expected, try closing and reopening any programs you're using to run and edit code.
-- The data returned by this endpoint is subject to various international laws and regulations, therefore the accuracy of the results depends on several factors. These factors include whether the number was ported, the country code, and the approval status of the caller. Based on these factors, operator information may not be available for some phone numbers or may reflect the original operator of the phone number, not the current operator.
