If your Free Fire account has been banned on iOS, you can follow these steps to reinstall the game and access it again:
1. Log out of your Apple ID in the App Store by tapping “Settings” > “iTunes & App Store” > tap your Apple ID at the top of the screen > tap “Sign Out.”
2. Uninstall Free Fire from your device.
3. Change or reset the IP address of your device (you can do this through a VPN).
4. Install Free Fire again using a new Apple ID in which you haven't previously played with that same device before. You may need to use a different email address than one used for an earlier account if trying to play multiple accounts on one device is prohibited by Garena's terms and conditions; please check their rules first before creating any additional accounts on one device/IP address.
5. Once installed, log back into your old account as normal – remember to use the same credentials you did prior to being banned! If successful, all previous data should be restored without issue and allow you to pick up where you left off without penalty or loss of progress/data due to ban status reversal after reinstalling successfully with new credentials following above steps accordingly.
