AWS SNS cross region vs same region cost and time difference

Question

如果我使用 aws sns 向澳大利亚号码发送短信但在设置 aws-sdk 的区域时我使用 ap-northeast-1 而不是 ap-southeast-2，那么成本计算是否有任何差异？

Answer 1

As far as I can tell from reading the documentation: no.

Looking at the pricing and entering Australia as the region prices vary by carrier.

There is no way to select a region for SNS so from that I conclude that the pricing is the same regardless in which region you use SNS.
