AWS SNS发送消息

Question

我们发现，在我们在文本上发送验证码后（使用aws sns），我们无法在同一个手机号码上发送另外的代码20分钟。有没有什么方法可以减少时间，类似于银行网站，我们可以在3-4分钟内将另一个代码发送到同一个手机号码。

Answer 1

You said SMS arrives after 20 mins or sometimes it doesn't arrive. Seems like a service provider's delay to me.

Do you get any error from SNS? You should check the CloudWatch's NumberOfNotificationsDelivered and NumberOfNotificationsFailed metrics to dig deeper into the problem.
