See if China Telecom charges! ! ! There must be something wrong!

Therefore, I have never believed in telecommunications and China Unicom. On the surface, their monthly rent and cost per minute are very low and attractive. However, the details of his fees are too opaque, and there are a lot of messy expenses. Some monthly subscriptions are not allowed by customers. It is said that the charge is much better now, but I still instinctively refuse.
