SNS Sandbox SMS delivery to US numbers

Question

Hello,

Currently, I'm trying to implement notifications for users of my application. 
I would like to test it while application is still in Sandbox. But for some reason I could not receive verification code for US number. It work for other contries, but not for USA.
Is it possible to verify and send test SMS with SNS while you are in Sandbox? 
If not, maybe there are other ways to delivery SMS to verified number? Because currently I'm not ready to register A2P 10DLC campaign.

Thanks

You need to set up an origination identity for SMS messages. Amazon SNS SMS messaging is available in Regions where Amazon Pinpoint is not currently supported . The below links provides instructions on how to use regions where pinpoint isn't supported. https://docs.aws.amazon.com/sns/latest/dg/channels-sms-originating-identities.html
