Your data goes through China
I'm in EU yet every single data packet from this provider is routed through China (Probably where their UPF actually is) and then back to EU. This means the ping is very high and even using VPN services is almost impossible because of the Great Firewall of China (GFW) . Additionally, the "Unlimited" data plan is not actually unlimited. After 10 GB they will throttle the data so much that you won't even be able to open up the google.com landing page. Stay away from this provider.
