Agricultural Bank of China credit card binding WeChat cannot be used, which may be due to insufficient available quota, exceeding payment limit, abnormal mobile phone network condition, and merchants not supporting credit card payment. The specific analysis is as follows:

1. Insufficient available credit card amount may lead to payment failure.

2. ABC credit card has a single payment limit and a daily payment limit. As long as the limit is exceeded, the payment cannot be completed.

3. If the cell phone network signal is poor or abnormal, you can't use the micro-card payment function.

4. Merchants do not support credit card payment. When merchants don't open the WeChat credit card payment function, they can't pay by credit card.
