AWS Toll Free Number #Without Sandbox

Hey Team,

Initially we were using AWS SNS service to send SMS to a person from application. For that it seems as a pre-requisites, we were using AWS Sandbox, where we were adding numbers and verifiying those and sending SMSs via application. Now our customer is US based and for that as per new process we have to opt for Toll free number and complete the registration. We have done with toll free process and receives the toll number with active status.

Now, is it ok if I exit from SMS sandbox from my AWS account ?? Or is there any additional process to be done ?? Since I tried to send one SMS to US number which has not gone successful but after verifying that number in Sandbox it was successfully received.

In actual scenario we don't want US numbers to be verify first. Application can directly send SMS to US numbers without verification from toll free which is already active.

If I exit from sandbox, will it impact toll free number, which we have activated ??
