Telegram which preceded WhatsApp with its multi-account support, channels and many more features, has removed the SIM requirement with the latest update. Also added a few extra privacy options for all users. The SIM card-free registration period has started in Telegram. It is now possible to open a new Telegram account without a SIM card, but users can log in to Telegram using their blockchain-backed anonymous numbers via the Fragment platform. It is worth noting that these anonymous numbers can only be used during and after registration with Telegram.

Telegram says its ultimate privacy is ensured, with the ability to delete messages from all participants without a trace, a timer to auto-delete both current and future chats, and use the account without a SIM card.

What's new with Telegram 9.2 update:

- Signing up without a SIM card (Anonymous sign-in)

- Auto-delete all chats (General auto-delete timer)

- Topics 2.0 (Organize discussions by topic)

- Aggressive anti-spam (New aggressive mode for automatic spam filters)

- Temporary QR codes (for those who hide phone numbers without usernames)

- Emoji search (on iOS)

- Detailed storage usage (on Android)
