Installation and first launch: what you need to know before registering

Install Telegram on Android can be done in three ways: through Google Play, downloading APK from the official website or using alternative stores like Aurora Store. The last option is relevant for devices without services Google (for example, on Huawei s AppGallery). Important: the version from Play Market is automatically updated, and “manual” installation requires tracking new releases.

When you first start, the system will ask for a phone number. There is a nuance here: Telegram links the account to the country of the number, and not to your location. If you use a virtual number (for example, through TextNow or OnlineSIM), select the country where the number is issued manually - this will affect the availability of some bots and channels. The confirmation code will be received either via SMS or via call (if the SMS does not arrive within 2 minutes).

• 📱 Official source: Install only from Google Play or from the site telegram.org - other sources may distribute modified versions with malicious code.
• 🔒 Phone number: Both physical SIM and virtual SIM are suitable for registration (but not all services support receiving SMS from Telegram).
• 🌍 Language interface: If after installation the language is displayed incorrectly, check the system settings - Telegram takes the language from global settings Android.

⚠️ Attention: If you register from a number that was previously linked to another account Telegram, the system will offer to restore the old profile. Refuse if you do not remember the two-factor authentication password - otherwise access to the new account will be blocked for 7 days.

Setting up a profile and security: why this is more important than it seems

After registration, most users are limited to uploading an avatar and specifying a name. But in Telegram there are critical security settingsthat should be configured right away:

1. Two-factor authentication (2FA): Go to Settings → Privacy and security → Two-step verification. Set a complex password (at least 12 characters with numbers and special characters) and save it in a password manager. Without 2FA, your account can be stolen through a SIM-swap attack.
2. Sessions: In the same section, check the list of active sessions. If you see unknown devices or IP addresses from other countries, end these sessions immediately.
3. Nickname (@username): Create a unique nickname in the format @your_name. This will allow them to find you without a phone number and use your account to authorize on sites through Telegram Login.

Pay special attention to the section Privacy:

• 👥 Last activity: Limit the visibility of your online to strangers (“No one” or “My contacts”).
• 📞 Calls: Disable calls from everyone except your contacts - this will protect against spam bots.
• 📍 Geolocation: Never share your exact location in chats. Use the "Approximate Location" function (available from version 9.4+).

Settings	Recommended value	Why is it important
Two-factor authentication	Enabled	Hacking protection via SIM card
Phone number visibility	"My contacts"	Reduces spam
Auto-download media	"Never" (for mobile data)	Saves traffic and space on the device
Deleting an account when inactive	6 months	Prevents data loss during long periods of inactivity
