More articles about "补贴", from same user, https://www.jianshu.com/u/3bff037f7a8b .

I assume the android implementation was done in China, then many requirements are related with "补贴", it is just part of them to submit some data to zzhc.vnet.cn. But didn't get deleted when they are making EU variants.

Thanks for the links. Actually, I had seen one of those articles before, but didn't understand it well enough.

My understanding now is that some 4G deployments are subsidized, and to correctly compute the amounts to be paid, China Telecom needs to collect more data than is usually available, so they came up with the idea of sending the data to zzhc.vnet.cn.

Still pretty hacky, but it kind of makes sense from a perspective of doing the minimum necessary to fulfill the requirements.
