Can I still receive SMS if I owe money on Unicom card?

If your mobile phone is in arrears but not turned off, it will not affect your functions such as making phone calls, surfing the Internet, sending and receiving short messages, etc. But if your mobile phone is turned off due to arrears, you can't surf the Internet, make phone calls or send and receive text messages. You must pay the fee before you can restore the functions of surfing the Internet, making phone calls and sending short messages. Generally, the delay of sending short messages is within 48 hours, so if you stop working due to arrears the day before, you can immediately pay the arrears, and you can start your computer normally tomorrow, and you can usually receive short messages.
