If you run into any issues during your first install, follow this guide
Go to Settings → Security (or Privacy) → look for "Install unknown apps" or "Unknown sources". Grant permission to your browser (Chrome). You only need to do this once.
Tap the "Android APK Download" button above. Your browser will ask — tap "Download anyway" or "Download" to confirm. Depending on your connection speed, the download should take around 10–30 seconds.
Once the download is complete, pull down the notification bar from the top. Tap the file named "399be.apk" or "399be-v3.2.1.apk".
A popup window will appear — tap the "Install" button. Installation completes in 15–30 seconds. Then tap "Open" to jump straight into the app.
Open the app and log in to your 399be account. New here? Register and claim your app download bonus (50% extra).
If you see a "Parse error" or "App not installed" message, it's usually due to an older Android version. Check your Android version by going to Settings → About Phone. If you're running below Android 5.8, use the PWA option instead.
Visit 399be.best on your iPhone using Safari — Safari only, not Chrome. The "Add to Home Screen" feature on iOS works exclusively through Safari.
Tap the Share icon (a square with an arrow pointing up) at the bottom centre of your screen. A menu will appear.
Scroll through the menu, find "Add to Home Screen" and tap it. You can rename it if you like — then tap "Add".
The 399be icon will be added to your home screen. Tap it for a full-screen, app-like experience — no browser bar in the way.
Visit 399be.best using Chrome on Android or your computer. Once the page loads, Chrome may automatically prompt you to install the PWA.
In the Chrome address bar, you'll see a small install icon (or "+" sign) on the right. Click it and confirm by tapping "Install".
Once installed, a 399be shortcut will appear on your desktop or home screen. It opens in its own window — just like a native app.

Bangladesh now has over 100 million mobile internet users. People want to do everything on their phones — from banking and shopping to reading the news and entertainment. Online betting is no different. 399be's own data shows that 7 out of every 10 active players use mobile. With that reality in mind, 399be built its mobile app.
The 399be Android APK download process may seem a little unfamiliar at first, since the app isn't available on the Google Play Store. In practice, it's straightforward — just enable "Unknown sources" once and install the APK. After that, future updates are delivered from within the app itself, so you won't need to download it all over again.
The app's interface is designed with Bangladeshi users in mind. All menus and options are available in Bangla, so you don't need to know English to navigate. The payment section integrates bKash, Nagad, and Rocket gateways directly — no need to switch to a separate app for deposits or withdrawals. Everything is handled right inside 399be.
The mobile app's edge in live betting is unmatched. During a cricket match, odds update before every single ball — and catching those shifts requires a fast response. On the 399be app, odds refresh in under one second. Unlike a website where you have to wait for the page to reload, the app updates odds automatically in real time.
Push notifications have proven especially useful for many players. Say you like to bet on the 7 PM cricket match every evening — with notifications enabled, the app will alert you half an hour before kick-off. You'll also be notified whenever a new promotion goes live or a deposit and withdrawal is confirmed, so there's no need to keep opening the app to check.
The 399be mobile app uses 256-bit SSL encryption. Your login credentials, payment data, and personal information are fully encrypted before being sent to the server. The app only requests the device permissions it actually needs — camera (profile photo), storage (cache), and notifications. No unnecessary permissions are asked for.
The PWA option is ideal for anyone who doesn't want to install an app on their device or doesn't have enough storage space. When added to your home screen, a PWA looks and feels exactly like a native app — but it's actually a website that behaves like one. 399be's PWA gives you full access to live betting, casino games, deposits, and withdrawals.
399be regularly rolls out new features with every app update. At least one update drops each month, bringing new games, performance improvements, or additional payment options. Android users receive update notifications and can install the latest version directly within the app. For iOS, simply repeat the "Add to Home Screen" step in Safari to get the latest version.
Make your first deposit through the 399be app and get a 50% bonus on top — an offer exclusive to mobile app users. Deposit ৳1,000 and you'll receive ৳1,500 in total, with an extra ৳500 credited to your account. Download and register today to claim this offer.
