Choose the right version for your device
Complete installation in just a few steps
Go to Settings on your Android phone → Security or Privacy → enable "Install unknown apps" or "Unknown sources". Without this, the APK file cannot be installed.
Click the "Download APK" button above. The download will begin and the file will be saved to your phone's Downloads folder. It typically takes 30–60 seconds.
Open the sm40 APK file from your File Manager or Notification bar. Tap "Install" and accept any permission requests. Installation completes in 5–10 seconds.
Open the sm40 app. Log in if you already have an account, or complete registration in just 2 minutes. You can start playing right away.
Only download the sm40 APK from the official sm40.onl site. Downloading from third-party sites or Telegram links may pose a security risk.
Use the Safari browser on your iPhone or iPad. Go to sm40.onl/download and tap the "Download for iOS" button. Chrome or Firefox may not work.
A popup will appear before the download begins — tap "Allow" or "Trust". Then go to Settings → General → VPN & Device Management and trust the sm40 profile.
Once installation is complete, the sm40 app icon will appear on your home screen. Open the app and log in to your account.
If you run into issues on iOS, open sm40.onl in Safari → tap the Share button → select "Add to Home Screen". It works just like the app — no separate installation needed.
Smartphone usage in Bangladesh is growing rapidly, and so is the demand for mobile online gaming and betting. sm40 has built a powerful mobile app in response to that demand — optimized specifically for Bangladesh's network conditions. The app runs smoothly on 3G, and delivers an even better experience on 4G or Wi-Fi.
The biggest advantage of the sm40 app is that it's fully featured — just like the website. From Live Casino streaming to Sports Betting, slots, and withdrawal requests, everything is available in the app. No need to open a browser or keep a bookmark. Jump straight into your favorite game with a single tap.
The app features push notifications. Alerts for new bonus offers, tournament reminders, and withdrawal confirmations are all delivered directly to your phone, so you never miss an offer. Many of sm40's special promotions are available exclusively to app users and are not offered to web users.
Security is another area where sm40 truly stands out. Biometric login support means you can access your account quickly and safely using Face ID or fingerprint — no need to remember passwords. All transactions are processed through encrypted connections, keeping your financial information completely protected.
The data saving mode is worth a special mention. Enabling it in the sm40 app reduces live game streaming quality slightly, cutting data usage by up to 40%. Even when you're running low on data at the end of the month, you can keep playing without interruption.
Downloading the sm40 app unlocks a special app-only bonus on your first login. App users also receive exclusive weekly cashback offers that are not available to web users.
