Playing Diablo Immortal online requires a lot of bandwidth, and most ISPs are known to throttle traffic from users who consume too much bandwidth to maintain good speeds across their entire network.

The only solution to this issue is to use a VPN and re-route all your gaming traffic via a VPN server. These VPNs provide a secure network connection where the traffic is encrypted, and you can bypass all the limitations imposed by your ISP. We have been using the Systweak VPN for a couple of years. We are fully satisfied with its performance, no-logs policy, and Kill Switch, which works when a server fails, disconnecting all connections so your online activity is not compromised.
