The signal in Langfang, Hebei Province is not good. How can I check the phone bill of the current month through SMS when I can't hear the other party's voice on the phone?

1, mobile phone signal is poor because the signal will be affected by various factors such as topography, landforms and tall buildings. If your location is relatively closed, the signal will be affected. You can restart your mobile phone, or change your mobile phone card to that of your family and friends and try again to see if the signals of other Unicom users around you are normal. If your signal problem has not been solved, please contact the customer service in your hometown for consultation.

2. you can log in to the online business hall/click "call charge inquiry" > "real-time call charge" or "account balance" to inquire about the call charge usage or account balance. If you still have questions after the inquiry, you can check the detailed list to understand the specific usage, or contact the local manual customer service or go to the local business hall to verify.
