Telegram will send a verification code to the secondary SIM.
Retrieve the code from the phone with the secondary SIM and enter it into Telegram on your main device.
Once verified, your Telegram account is now linked to your secondary number. You can then remove the secondary SIM from the other phone if you wish, as your Telegram account is cloud-based.
Pros: Generally more reliable for SMS verification than free virtual numbers.Cons: Requires a physical SIM card, which might be an extra cost or hassle.
Important Considerations for All Methods:
Two-Step Verification (2FA): Regardless of the telegram number database number type you use, always enable Two-Step Verification (2FA) in Telegram's settings. This adds a crucial password layer to your account. If someone were to gain access to your virtual/secondary number, they still wouldn't be able to log into your Telegram account without this 2FA password.
Number Longevity: For virtual numbers, ensure you understand the provider's terms regarding number permanence. If a temporary number expires, you could lose access to your Telegram account if you haven't changed the number within Telegram or kept the virtual number active.
Security: Always download the official Telegram app from reputable app stores (Google Play, Apple App Store) or Telegram's official website. Avoid unofficial third-party clients, as they can compromise your privacy and security.
By choosing one of these methods, you can successfully set up and use Telegram without directly linking it to your primary personal phone number, giving you greater control over your privacy. These numbers typically start with +888.
You can use such a number to register your Telegram account, providing a unique method of identity not tied to a real-world carrier subscription.
