Please consult the Unicom 3g card I bought. The set meal is also 3G. The mobile phone said it was out of service, but I tried to send text messages. I just want to know how much I owe.

Unicom 3G post-paid users can continue to use the arrears within the credit line of the current month, and will generally be prompted to stop on the 25th of the following month. At present, it is temporarily impossible to inquire about the arrears of last month through the online business hall. You need to contact your Unicom customer service for your inquiry. At the beginning of the month 100 10, the line was busy and it was difficult to dial. I suggest you move to Unicom business hall or call the business hall to inquire.

What is the query method of Unicom business hall? /oftenInfo.html？ menuId = 0004000 1000 1？
