Setting up a proxy IP is required for cloud phones. The main reasons are:

1. Bypass IP Restrictions: Many websites or apps set IP restrictions during marketing promotions, account registration, etc., such as regional access limits, app download permissions, and single-IP registration caps. By setting up a proxy IP, users can easily bypass these obstacles and successfully access, download, or register blocked resources.

2. Maintain Anonymity: A proxy IP can hide the real IP address of the cloud phone, preventing the target server from directly tracking the network request source. This helps protect the privacy and security of cloud phone users and reduces the risk of being tracked or banned.

3. Avoid Account Association: By setting up a unique proxy IP for each cloud phone, each account can operate in an isolated network environment, avoiding account risk control due to IP association. This enhances account security and stability and enables efficient, independent operations of multiple accounts.
