This tutorial distills the full, mobile-first workflow to create a Telegram account on Android or iPhone, with step-by-step guidance and security best practices. You’ll learn how to find and install the official Telegram app from Google Play or the App Store, grant required permissions (phone, notifications, contacts), select your correct country/region code, and enter a reachable phone number. Depending on your region or device, Telegram may ask for an email check before the one-time password (OTP) via SMS or automated voice call—this guide shows how to complete both, then set your profile name/photo and enable contact sync and notifications as needed. To keep your account safe, we cover enabling two-factor authentication (2FA), setting a local app passcode/PIN, adding a recovery email, and key privacy controls (hide phone number, who can find you, who can add you to groups). Finally, you’ll get fast troubleshooting for missing codes, carrier blocks, Do Not Disturb issues, wrong country code, and common pitfalls with VoIP numbers, plus clear explanations of usernames vs phone numbers, channels vs groups, and how to change number, back up, or delete your account.
