I understand your frustration with your ISP blocking the trick you used. Unfortunately, using VPNs to access free 3G/4G internet can often be against the terms of service of both the ISP and the VPN provider, and ISPs may block such methods to prevent misuse.
Instead of looking for tricks, I recommend considering legitimate options:
Check for Promotions: Sometimes ISPs offer promotions or trials for free or discounted 3G/4G data.
Use Public Wi-Fi: Look for public Wi-Fi networks in your area, though be cautious with security.
Contact ISP: Reach out to your ISP to see if they have any affordable plans or solutions for your needs.
