Frequently Asked Questions
Everything you need to know about the April 2026 Undersea Mystery update.
What is the Free Fire Advance Server?
It is a separate testing client used by Garena to test upcoming features like the OB53 Undersea Realm and the new Horse vehicle before they are released to the global version.
How do I get an Activation Code for OB53?
You must register on the official Garena Advance Server portal using a linked Facebook or Google account. Once approved, the 16-character code will appear on your dashboard.
Will my main account be banned for playing the Beta?
No. The Beta is an official Garena application that runs in a sandbox environment. It does not interfere with your Global or Free Fire MAX account data.
Can I play the Advance Server on iOS (iPhone)?
Currently, the OB53 Advance Server is only available for Android users. There is no official IPA file for iOS devices at this time.
Why does my Activation Code say “Invalid”?
This usually happens if the code was copied incorrectly (it is case-sensitive) or if the server has reached its maximum player capacity. Ensure you copy the code directly from the official portal.
Do I keep the Diamonds I earn in the Beta?
The Diamonds in the Beta are for testing purposes only and do not transfer. However, if you find bugs and report them, Garena sends real Diamonds to your main Global account as a reward.
What are the minimum specs for the OB53 update?
You need at least Android 5.0, 3GB of RAM, and 2.5GB of free storage. The OB53 update is optimized with the Vulkan API for better performance on mid-range devices.
