SMS credits are needed for SMS/Text alerts to work
One credit is used for each SMS alert sent to a mobile phone. So, if 2 different people are to receive both an SMS when a service goes down and when it comes back up again, 4 credits will be used.
SMS credits are included in your subscription!
This means that each month your account will be refilled with a certain amount of credits. They are refilled on the 1st of each month, both for monthly and yearly subscription plans.
The amount of credits you get depends on what subscription plan you have
Check your subscription page for the number of credits you currently have and to see how many you'll get automatically refilled monthly.
What happens if you run out of credits before the refill date?
To avoid completely running out of credits and miss important alerts you can activate autofill of SMS credits on the Subscription page in your account! With this feature, you can set the system to automatically purchase SMS credits when you need them, for example, when your credit count goes down to 5 you can set it to buy 20 extra credits.
It's possible that you have more than these amounts as we've previously allowed the purchase of individual credits. If you purchased SMS credits or you still have SMS credits leftover from when you first signed up, you can still use those SMS credits.
You can check your SMS credit balance on your subscription page in my Pingdom.
Our system will use those SMS credits until your balance is zero - then, we will replenish your account with the monthly allotment.
