Creating a phone number verified Gmail account can be a bit tricky, but it's definitely possible. One way to do this is by using a temporary phone number from a service like Quackr or receive-sms.com.
Using temporary phone numbers online can be useful, but it's important to use them responsibly and by each service's terms and policies. Once you have a temporary phone number, you can use it to create a new Gmail account. During the account creation process, Gmail will send a verification code to the phone number you provided. Simply enter the code on the Gmail sign-up page, and your account should be verified. Best of luck!
