The customer service is full marks.
Because I also have to pay with usdt, I was a little worried when I saw the previous comments, but the Black Friday price was really good,so I bought it with the idea of trying it. At first, because the quota in Singapore was used up, I paid and couldn't activate it successfully. However, after contacting customer service, the customer service team Mark Liu immediately accompanied me to find out the problem and solve it. I just started using it so I can't comment on the stability. The customer service part is full marks thought.
