Unable to send SMS from Zabbix after few successful attempts

[yihchawkong]

Hi,

I just completed setup my Zabbix in AWS (ubuntu) and configured SNS for SMS notification.

Everything went smooth and I was able to receive the SMS alert from Zabbix. But after testing for few more times, the SMS was not received, but when I checked the "Action Log", the status was "Sent".

Is it I'm running out of credit for the SMS feature? Or anyone have similar experience on this?

This is tutorial I followed for the SMS Alert setup.
