What is the monthly consumption limit of Unicom mobile phone? How can we raise the consumption limit!

Unicom mobile phone has no consumption restrictions, as long as you have phone bills in your mobile phone. However, the consumption items you mentioned belong to Tencent's business, and not all Unicom numbers in all regions can open such business. If you don't support it when you open Tencent's business page, your number can't handle this kind of consumer business.
