## China Unicom Cloud (联通云盘 / 沃盘, pan.wo.cn)

- `netdisk-pan/china-unicom-wopan` | trial-only | evidence reported | binding per-object-cap | category carrier cloud
- needs card no, phone yes, ID no, institution no | verified 2026-11-04T00:20:53.783Z (inherited) | stale on 2026-11-19
- url https://pan.wo.cn
- free tier: 60 GB free, raised from 10 GB by a promotion from 2025-09-01 to 15 that was made permanent: '免费用户存储空间 由10GB 提升至60GB，空间长期有效'. Non-Unicom numbers can register | unit: GiB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: Not published in what was read | source: [2]
- retention: The 60 GB is stated as 长期有效, long-term valid. Promotional grants of 8 TB run one year | source: [1]
- egress: Advertised 不限速 on the homepage. One poster measured cross-carrier throughput through OpenList and WebDAV at their full 100 Mbit/s up and 500 Mbit/s down, so unlike Tianyi it is not throttled cross-carrier | metered: no | source: [3]
- identity: country-phone | detail: a PRC number, with a non-Unicom number accepted: '非联通用户也能注册'. A promo code is the alternative path | country: 86
- interface: rest, webdav
- limits:
  - per-object-cap (binding): 60 GB is the free tier total, which is the cap in practice [1]
  - write-gated: registration wants a Unicom number or a promo code; a non-Unicom number is accepted but still a Chinese one [2]
- binding note: The per-file cap is unpublished, so the account total is what binds, and 60 GB does not reach the filter at any identity cost.
- tooling: the OpenList wopan driver, which mounts through the web client with a refresh token and an access token that a helper tool mints or that are captured from the browser. The OpenList documentation calls the interface a reverse-engineered one that the OpenList project does not actively maintain. A separate Go SDK, OpenListTeam/wopan-sdk-go, takes a refresh token
- composes with: 60 GB per account and phone-bound, so each additional carrier number is a new identity. Carrier family sharing pools within a household. Not a 500 GB play without multiplication
- reliability: The quota is promotional and has already changed once, and the operator drives historically shrink free tiers after a growth phase. Multiple posters describe the product as under-resourced with a slow interface, and the WebDAV mount and the cross-network speed are the best of the three carrier pans
- notes: A carrier pan reached through an OpenList driver and a separate Go SDK; the OpenList documentation calls the interface reverse-engineered and not actively maintained by that project. Two earlier records disagreed: one called it trial-only on a one-year promo and one called it fails-quota on the permanent free tier. Both are right about different tiers, and the verdict follows the permanent tier because the promo is time-limited. A third-party table now lists a larger free quota, which is open to a check
- extras:
  - access_mode: registration-gated
  - sdk: OpenListTeam/wopan-sdk-go, maintained
  - cross_carrier_unthrottled: yes
  - aliases: 联通云盘 (China Unicom); 联通云盘 / China Unicom Cloud (pan.wo.cn); 联通云盘 / 沃盘 WoPan; WoPan

  - [8] 2026-11-03: the table row lists 500G free, a 2G upload limit and a 0.5M/s download limit, unlike the 60 GB and unthrottled figures of this record | capture: sha256:87cfd4212b0eaf2bb73b16353c13f114920639a0b2df7d9e3a6465f3bf0ce870 | quote: | 联通云盘 | 500G | 2G | | | 0.5M/s | | |
