FAQ

Deposits to 399btd via Mobile Pay or Nagad typically reflect within 2 to 10 minutes. Occasionally, network issues or payment gateway delays may push this to up to 30 minutes — just refresh the page and wait it out. If your balance still hasn't updated after 30 minutes, take a screenshot of the transaction in your Mobile Pay app and reach out via Live Chat. Sharing the transaction ID helps the team resolve it faster. If the deposit didn't go through, any amount deducted from Mobile Pay will be refunded. Never send the same amount twice — if something goes wrong, contact Support and let them handle it.

Absolutely. The 399btd website works seamlessly on mobile browsers. Just open 399btd.biz in Chrome, Firefox, or any modern browser, log in, and jump into any game or betting market.
