Unicom card without long-distance phone bill can't receive short messages.

You can't receive text messages after the phone card is in arrears. I'm lucky if I can still receive it all the time, but it's unlikely that I should be in a semi-shutdown state now, and I can still answer the phone and receive text messages. However, if the mobile phone card is in arrears for more than three months, it will automatically cancel the account, and then you will not receive the SMS. Please decide whether to continue using the mobile phone card as soon as possible. If you use it, you can continue to use it after recharging and paying. If you don't use it, you can pay off your debts without a contract, cancel your account, and avoid the accumulation of debts under your account.
