OpenAI has launched a beta feature allowing new ChatGPT users in the U.S. and India to register using only a phone number, eliminating the need for an email address. However, this method comes with restrictions, including the inability to upgrade to paid plans without verifying via email. Recycled phone numbers may cause errors, with no current workaround available. OpenAI aims to lower barriers for product access, having earlier introduced phone chat functionality and WhatsApp integration. Despite a significant user base, OpenAI faces financial losses and is exploring pricing adjustments.
