No, you cannot do this. CloudWatch will only post SNS themes that are in the same region as your cloud alerts / alarms.
But you may have a workaround like this answer
, :
> CloudWatch Alarm (ap-south-1)
> -> SNS (ap-south-1)
> -> Lambda (you can have this in any region, cross region lambda can be invoked from sns)
> -> SNS (us-east-1), invoked from lambda
> -> SMS subscriber (us-east-1)
