I have used free trial account but 100$ were not deducted, just 1$ was deducted for verification purpose.
Why do I need to provide a credit card and phone number?
One of the ways we keep prices low is to verify that account holders are real people, not bots or anonymous troublemakers. We use the phone number and credit card for identity verification. We don’t charge your credit card anything, but you may see a one-dollar verification hold on your credit card account, which is removed within three to five days.
