If you use Google Fi’s cellular data in China, you can access sites typically blocked by GFW (source: first hand experience). So I assume the answer is yes. Not sure which entities have such access though.

Edit: IIRC some local friends from Peking University and Tsinghua University once told me that they could use Google and stuff (also typically out of reach) from their college dorms.

All foreign roaming users can get through the GFW. The local carrier sends everything through what is basically a VPN to your home cell carrier so it can be properly billed. A popular way to get around GFW for those with money is to use an HK cell phone in China.
