Auto Top-Up
Adding a payment method to your Space turns on Auto Top-Up. When your balance falls below a threshold you set, SignalWire charges the card you chose and adds the funds to your balance. This keeps calls and messages running, and keeps recurring charges such as phone numbers paid.
You can change the amount, the threshold, and the card that funds it, but the Dashboard does not offer a way to switch Auto Top-Up off once it is on. To turn it off, contact Support.
When you are charged
The charge is normally the top-up amount. If topping up by that amount would still leave your balance at or below the threshold, SignalWire charges enough to clear the threshold and add the top-up amount on top. The amount charged can therefore be larger than the amount you configured.
With a threshold of $50 and a top-up amount of $10, a balance that falls to $5 is charged $55.
Auto Top-Up charges at most once every six hours. A Space that spends faster than that can reach a zero balance between charges and lose service until the next one, so set a top-up amount that covers six hours of your own traffic.
Some features require Auto Top-Up to be active before you can use them.
Registering a campaign with The Campaign Registry is one of them, and returns the auto_top_up_deactivated error while Auto Top-Up is off.
Change your settings
Open Billing → Low Balance Settings in the Dashboard to change the top-up amount, the threshold, and which card funds Auto Top-Up.
Remove the card that funds Auto Top-Up
A card cannot be removed while it is your Auto Top-Up payment method. To remove it:
If a charge fails
If the charge is declined, or no valid card is on file to charge, SignalWire turns Auto Top-Up off and emails your Space administrators. Adding a payment method or topping up your balance manually turns it back on.
