Which VPN definitely works in whitelist mode?
There is no universal answer. It depends on operator, region, filtering mode and the available route to the server.
Whitelist mode
VPN and whitelist mode: why only part of the internet may open
Whitelist mode means the network allows only a limited set of approved services. In this scenario, a regular foreign VPN may fail to connect even if it works normally on other days.
What to understand
this is not a normal block of one website, but a broader route restriction
if only local services open, some VPNs may have no path to the server
VLESS Reality and Hysteria 2 help against many DPI scenarios, but do not guarantee strict whitelist bypass
the actual result depends on operator, region and timing
What to check
1
Check whether foreign websites open without VPN at all.
2
Test WersidePN on mobile data and Wi-Fi separately.
3
If only local services open, note the operator and region.
4
Contact support: this scenario requires route diagnostics.
Common questions
Why did VPN work yesterday but fail today?
Restrictions can be local and temporary. Whitelist mode affects not only websites, but also the ability to reach a VPN server.
Should I buy VPN only for whitelist mode?
Test first. For this scenario, trial and support are more honest than promises without verification.
