During your trial period you will not be charged for the agent's subscription fee.
You will be charged for phone numbers, inbound calls, and outbound calls according to the country's call rates. This cost is deducted from the account credit that you can manually add.
After your trial ends, your account starts being charged according to your contract effective start date.
Note: Your trial account includes a $5 credit that you can use towards calls and the purchase of phone numbers in your Talkdesk account.
