Unfortunately, Grand Theft Auto V (GTA 5) is not currently available for mobile devices. The game was originally released for Xbox 360 and PlayStation 3 in 2013, and has since been made available on a number of other platforms, including Xbox One, PlayStation 4, PC, and even Google Stadia, but it is not available on mobile devices.
If you want to play a mobile game set in the Grand Theft Auto universe, you can try Grand Theft Auto: San Andreas, which is available on both iOS and Android. However, it’s worth noting that while San Andreas is a great mobile game in its own right, it is not the same as GTA 5.
