Mobile access in three moves
Open your browser and navigate to gt77 — the site detects your screen size and serves the mobile layout automatically. Check the account menu for any native-app availability notice; if we currently offer an APK or store listing for Bangladesh, you'll see a download link there with device requirements and file verification instructions. Sign in using your existing username and PIN, or
tap the OTP option to receive a one-time code via SMS if you prefer passwordless entry. Your account balance, transaction history and saved payment methods sync instantly, and the lobby layout adjusts to portrait or landscape as you rotate your device. Bookmark the page or add it to your home screen so future visits skip the address bar entirely.
- Navigate to the site — Type gt77 into your mobile browser — Chrome, Firefox or Safari all render the lobby correctly, and the page adapts to your screen width without pinch-zooming or horizontal scroll.
- Check app availability — Tap the menu icon and look for the app-download card; if a native build is live for your region, that card displays Android or iOS instructions, file size and the current version number.
- Sign in securely — Enter your username and password, or choose SMS OTP for code-based login — two-factor prompts appear if you enabled them in settings, and biometric unlock activates once you've logged in successfully on that device.
