| Binding | per-ip-shaping 0.5 Mbps is 5.27 GB/day at line rate, about 162 GB over 30 days, against the 3.24 Mbps that 1 TiB/month needs. Unlimited traffic is true and useless at this speed. |

| Identity | email The registration form asks for username, email, emailed verification code and password. No mobile number field and no real-name step appear on it. |
|---|
| Egress | Traffic is stated as unlimited on the free plan, with no byte counter named anywhere. The binding number is the speed: 0.5 Mbps sustained for 30 days is about 162 GB, so the plan cannot reach 1 TiB/month even at line rate.; ingress: udp free allowance: none published |

| Composes with | Two fixed UDP ports at 0.5 Mbps is enough for a WG control channel and a trickle, not for bulk transfer; pair it with a metered free VM for the volume. |
|---|
| Reliability | Daily check-in adds time to the free mapping rather than traffic, so a free tunnel can expire; the vendor states it is a small operation with no guaranteed support. |
|---|
| Notes | The only provider that pairs UDP ingress with email-only registration, so it is the cheapest to test of the Chinese set. Whether the two TCP/UDP ports are fixed for the life of the mapping is not stated on the pages read. A licensed operator: the footer carries a value-added telecom licence and a domestic VPN service licence. |
|---|
| Evidence note | documented Plan table and registration form both read first-party. What would raise the rung is a probe measuring whether the 0.5 Mbps is per tunnel or per account, and whether the two assigned ports survive a reconnect. |
