As you use Twilio services (minutes, SMS messages, phone numbers, transcriptions, etc.) we draw down your account balance. We’ll notify you by email when your balance hits $5.00 and again when your balance reaches $0. When your account reaches $0, your account will be suspended.
On your billing page, you can manually recharge, or have us automatically recharge your balance when it falls below a chosen threshold.
If you have Auto Recharge on your account, your account will be billed if it goes below $10 by default. You can change this default to up to $1000.00 in your account’s Auto Recharge preferences.
