Hello,
Yes, it is possible to use a VPN to make your Converge connection appear as if it is coming from a PLDT network. By connecting to a VPN server that is using PLDT as its ISP, your internet traffic will be routed through that server, giving the appearance that you are using a PLDT connection.
However, please keep in mind that using a VPN to mask your ISP may have legal and ethical implications. Make sure you are not violating any terms of service or agreements with your ISP by using a VPN to misrepresent your network connection.
If you have any specific questions or concerns about setting up a VPN to achieve this, feel free to ask for assistance. Thank you.
