I think you have a zero quota pass to the Great Wall around the world. If you don't need it, you can cancel it and call customer service to activate it if necessary.

Two ways to increase the quota:

1: Call the customer service, and then they fax an application form. You can fill it out and send it back, and then attach your own economic certificate. Of course, the amount depends on your financial situation.

2. You can deposit the money in the card first, and then spend it by credit card. There is no handling fee. It took a little more. Generally, I called the customer service three months later and asked her to raise the amount.

This zero line card is very good. Many of my friends even took the initiative to apply to reduce their credit limit to zero, because after it is reduced to zero, there will be no overdraft.

And it is also a credit card, with credit card points, and there is no handling fee for cash withdrawal. Don't you think it's great?
