Free Fire Guest Accounts Disappear Following Mobile Phone Upgrades

I was playing Free Fire on my Android device using a guest account, but after switching to a new phone, I lost access to the account entirely. Because this was strictly a guest profile, I had not yet linked it to Facebook, Google, or any third-party service. My in-game Player UID is 2988442469.

I request assistance in recovering my original guest account and transferring my saved game data and progress to my new device. Please let me know if there are any specific steps or verification details required to restore my account.
