To send and receive SMS messages from leads you need to ensure you have enough SMS credit in your account.
Account owners, admins and Franchise owners can view and top up their SMS accounts by navigating to Settings > SMS Accounts.
To add funds to your account, simply enter a round amount in and click Top-up Account.
If you want your account to top up automatically, simply click the 'Turn auto recharge on' button and confirm. If this is on it will automatically top up your account with $20.00 credit if it drops below $5.00.
The account owner will be notified of any manual or automatic top-ups by email, and an invoice will be available in the billing section.
