Many users hesitate the first time they install an APK — especially when the phone says "This file may be unsafe to install." There's no need to worry. Android shows this warning for any APK installed outside the Google Play Store; it's a standard security message, not a sign that anything is wrong.
To install apps from outside the Google Play Store on Android, you need to enable Unknown Sources or "Install from Unknown Apps" in your settings. This is a one-time change you can turn off again after installation. The gtt99 app is completely safe and free of malware.
The gtt99 Android APK is around 28 MB and the iOS app is around 31 MB. After installation, cached data may bring total storage usage to 80–100 MB. This is not an issue on most modern smartphones. If your device is low on space, free up some storage by deleting old files first.
The gtt99 app runs reasonably well on 3G, but for the best experience, use 4G or Wi-Fi. A stronger connection makes a big difference in Live Casino games and Sports Betting. Slots tend to use less data overall.
When a new update is available for the gtt99 app, you'll get a notification automatically at login. Just download the new APK and install it the same way as before — your account data will be fully preserved. On iOS, updates happen automatically.
Yes, your gtt99 account can be used on both the mobile app and desktop browser. However, playing on multiple devices simultaneously is not supported — logging in on one device will log you out of the other. This is for security purposes.
Open the gtt99 app and you'll find a huge slots collection, Sports Betting, bingo, Live Casino, a VIP section, and deposit and withdrawal — all in one place, no need to download separate apps.
