Can Unicom's number card receive short messages?

After the number is down, you can't answer the phone and send text messages normally. The number is down, not owing money. Only save the number without deducting the monthly package fee, and you need to leave enough balance to pay the number guarantee fee. When the balance is insufficient, it will cause downtime arrears, and the downtime arrears will be cancelled for more than three months. But if there is an agreement, the monthly consumption amount is not allowed. The length of the quantity guarantee depends on the operator's rules.
