Can I send text messages when my mobile phone is turned off?

When the phone is down, the system will keep information for you for up to 72 hours.

Unicom Telecom maintains 48 hours, and the website messages for 24 hours.

Take Unicom users as an example, there are two situations when the mobile phone stops:

1, half stop: you can receive short messages and answer calls; You can't make phone calls, send text messages or surf the Internet.

Half-downtime due to arrears means that the user fails to pay the fee within the specified time (the payment period is from 5th to 25th of each month), and the user number will be half-downtime on 26th. If the arrears of last month have not been paid off on the 29th, it will enter a state of complete shutdown, and the mobile phone number will not be used normally.

2. Stop completely: When the mobile phone stops completely, all services cannot be used.

If the payment is overdue, the service provider will terminate all communication functions of the mobile phone and interrupt all services.

Extended data:

1. When the mobile phone stops due to arrears, the user can restart it by recharging the mobile phone account.

2. Post-paid users can call the customer service hotline 100 10 to apply for credit startup, and ordinary users can enjoy such emergency credit startup once a month.
