Free VPN recommendation?

Backstory - So, our government cut off internet service for 4/5 days because there was a protest and they (the police) killed more than 250 unarmed students. Now they turned internet service back on with limited bandwidth and blocked all social media.

Can you guys suggest me any free vpn that can be used to bypass the government ban and is not super slow? I know I shouldn’t use free vpns but I really need to talk to my friends and family.
