Monitor your monthly data usage. Your ISP is not always at fault for internet speed throttling.
Switch to a new internet provider. If youre frustrated with your ISP, switch to another if you can.
Use a VPN.
VPN will encrypt your traffic, and your ISP won't see what you do online. It helps in cases when throttling is implemented for specific websites or services.
In most cases, the throttling of an internet connection is legal. One common reason that data is throttled is due to excess use on a plan with a data cap. In almost all cases, ISPs are obligated to inform consumers when they throttle connections.
How Can I Bypass ISP Throttling Without a VPN? Although you could use a proxy server to try to avoid ISP throttling, a VPN is by far the best solution because it provides better security. You can even try a good free VPN, like Windscribe.
