Why am I unable to access certain websites on my mobile data?

Check your data plan
Check to make sure you haven’t exhausted your data limit or overage, and your plan supports the sites you’re trying to access.
Try Wi-Fi
Many sites, such as those for streaming audio and video, require more bandwidth than mobile data offers. Switch to a better network – such as Wi-Fi – to access them.
Don't use proxy or VPN
Proxy servers and VPNs can block access to some sites, as well as add more latency to your connection. Make sure to disable these if you’re facing issues.
Check services outages
Sometimes, sites may be down due to by service outages or maintenance. Try visiting an alternative page, or contact the website owner if the issue persists.
Talk to your provider
If nothing else works, contact your mobile provider to make sure the site isn’t blocked, or you are not encountering any other issues which may be preventing your access.
