amazon aws sns, sms option not available?

For other people that have this problem http://aws.amazon.com/sns/faqs/ -> SMS Related Questions section. It was very helpful for me.

"Q: Does Amazon SNS currently support notification delivery to international phone numbers? Currently Amazon SNS will only accept US phone numbers as valid subscription end-points."

never mind... apparently SMS only works on us-east region, you need to change the region from the sns management page. All seem normal now.

Update: SMS now works from 6 regions and SMS messages can be sent to some 200 countries.

These regions will work.

US East (N. Virginia) US West (Oregon) EU (Ireland)
Asia Pacific (Tokyo)
Asia Pacific (Singapore) Asia Pacific (Sydney)

The complete list of supported countries and regions is available here: https://docs.aws.amazon.com/sns/latest/dg/sms_supported-countries.html
