How to check the cost of Guanghan natural gas by mobile phone? Is there a special app?

Let's see if Alipay supports Guanghan. If so, you can watch it on Alipay. If not, you can't. Or you can go to the natural gas company to apply for a new IoT gas meter. Similar to a smart meter. You can charge hundreds of dollars at a time, and your balance will be displayed on the meter at any time. Charge the money when it is used up. After paying the fee, the latest balance will be displayed on the gas meter, so there is no need to insert a card to read the card like an electric meter. Now Guanghan should use this gas meter to install natural gas.
