Follow these tips to keep your account secure
All major Bangladeshi mobile banking methods are supported at 3999bt
To make a deposit after logging in, go to the "Wallet" section of your account. Funds are usually added to your balance within 1–5 minutes. If you run into any issues, contact live chat straight away.
Millions of members log in to 3999bt every day — most of them on mobile, whether they're on the bus, taking a break, or catching a match right as it kicks off. With that reality in mind, 3999bt's login system is built to be fast, secure, and hassle-free.
The login page offers two options — mobile number or email. Most members go with their mobile number since it's easier to remember. You can just as easily log in with your email. Either way, the same level of security applies.
Forgetting your password happens to everyone. Just click the "Forgot your password?" link, enter your registered mobile number or email, and an OTP will be sent to you. Use that OTP to set a new password. The whole process takes under 5 minutes.
If you no longer have access to the mobile number or email used during registration, contact 3999bt support via live chat. They will verify your identity and help recover your account. Having completed KYC verification makes this process significantly easier.
Yes, you can be logged in to 3999bt on multiple devices at the same time. For example, you could be placing bets on your laptop while checking scores on your phone — both using the same account simultaneously. If a login attempt is made from an unfamiliar device, however, you'll receive a warning and may be asked to verify via OTP.
If you ever suspect unauthorized access to your account — such as an unexpected drop in balance or unfamiliar betting transactions — change your password immediately and notify 3999bt via Live Chat. The sooner you report it, the faster it gets resolved.
After logging in to 3999bt, you'll land straight on your dashboard. Your balance is shown at the top, and if you have an active bonus, a notification will appear. To place bets, head to the "Bet" section — you'll find a list of ongoing matches there. To play Live Casino, click on that section and choose your preferred table.
It's worth checking the "Promotions" section on your dashboard regularly — especially so you don't miss weekly cashback offers or special event deals. Daily check-in bonuses are credited automatically, but some event bonuses need to be claimed manually.
After logging in, head to Account Settings and take a moment to review the Responsible Gaming section — setting a deposit limit or session timer helps you stay in control of your play. Responsible Gaming Full details are available on the page.
Answers to common questions about login and payments
There are several reasons why the app may not open — most issues are easy to resolve.
Check this first: Check whether the app is running an outdated version. Visit the Play Store or 3999bt's official download page to get the latest update. Older versions can stop working unexpectedly because they are no longer in sync with server-side updates.
If the app crashes: Clear the app cache from your phone's settings (Settings > Apps > 3999bt > Clear Cache), then relaunch the app. This fixes the issue most of the time.
If clearing the cache doesn't help: Uninstall the app and reinstall it fresh. Uninstalling will not affect your account or balance — it simply clears the app data and reloads everything from scratch.
If the app isn't functioning properly: Open 3999bt.best in your mobile browser (Chrome or Firefox) and log in — the web version works just as well. If you suspect a server issue, contact live chat and check the official social media pages for any maintenance notices.
3999bt supports all major mobile banking services in Bangladesh. After logging in, head to the Wallet section to see all available options.
bKash: The most widely used method in Bangladesh. Simply send money to the bKash number on 3999bt's deposit page — your balance is typically credited within 1–3 minutes.
Nagad: Many members prefer Nagad due to its lower fees. Deposit speeds are just as fast as bKash.
Rocket (DBBL): Dutch-Bangla Bank's mobile banking service. Reliable, with bank transfer support as well.
Which is the fastest? In most cases, your balance is updated within 1–5 minutes regardless of the method used. During peak hours at night or before big matches, it may take a few minutes longer.
Important: When making a deposit, always send to the number shown on 3999bt's page — not to any other number. If your balance hasn't appeared after 15 minutes, contact live chat with your transaction ID.
