Very often we were receiving e-mails from our users stating that their server was down, but they didn’t get SMS notifications. After investigating these issues, it turned out that SMS accounts of those users were exhausted. To avoid such complains in future and to inform our users earlier regarding their SMS account usage, from now on the users will receive SMS from Monitis stating that they reached their available limit of SMS notifications, so if they want to continue receiving SMS notifications they need to refill(buy) additional SMS credits. Thus, you can avoid any unexpected downtimes by filling in quickly and on time your SMS account and continue receiving SMS notifications afterwards.
