You can choose to be informed when your balance on SMS.to reaches a defined threshold, so you will be able to add new funds in time to prevent SMS or other billed actions to be rejected due to low balance.
Here you can choose to activate the notifications and are also able to define the threshold value. Whenever your balance will go below this value, you will be informed about this by SMS.
We might also be able to offer you an automated top-up function, which will automatically make a payment as soon as your balance falls under a certain pre-defines threshold. Please contact us at email@example.com in case you are interested.
Notifications about low balance can take up to 10 minutes so we suggest to configure it always with a large enough buffer to reflect frequency and volume of your balance consumption.
