To create a Telegram account without using a phone number, it’s generally not possible, as Telegram requires phone number verification for registration. However, you can use a virtual number or a temporary phone number service to bypass using your personal phone number. Some services provide temporary or disposable phone numbers for verification purposes.
As for the IP, it can matter in Telegram for security reasons. If you log in from different IPs, especially from different locations, Telegram may flag your account for suspicious activity and prompt you for additional verification. To avoid issues, try to use a stable IP and avoid switching locations frequently, especially when creating multiple accounts.
