Can't I use my mobile phone if the balance of my mobile phone is insufficient?

When the balance is less than 20 yuan, SMS will remind you to recharge. It is a balance reminder, and you can change the reminder amount yourself.

China Mobile has cancelled the restriction that callers cannot make calls when the phone bill balance is lower than 10 yuan.

At present, prepaid users of China Mobile can make phone calls as long as the phone bill balance is greater than 1 yuan, and they can also connect GPRS to surf the Internet and send and receive multimedia messages. However, when the phone bill balance is less than 10 yuan, they cannot use it normally.
