Open AltStore on your device, go to the "My Apps" tab, tap the "+" icon in the top-left corner, and select your verified GTA: San Andreas IPA file.

Free, verified files usually do not come pre-modified. If an IPA claims to have unlimited money or hacks, it is more likely to contain malicious code.

If your IPA supports Social Club integration, log in to keep your save games backed up across installs. Safety and Legality Reminder

If your device runs a compatible iOS version (typically iOS 14.0 to 17.0, depending on specific exploits), TrollStore offers a permanent installation method that never expires.

If you have a paid Apple Developer Account ($99/year), you can use Xcode or Apple Configurator to permanently sign the GTA San Andreas IPA file. Apps signed with a paid developer certificate will remain active on your phone for a full year without needing a weekly refresh. A Better Alternative: Play Legally via Netflix or App Store
