Why is Unicom's SMS service unsuccessful?

First, check the mobile phone network settings to see if the data connection is turned on. Check whether the short message is sent incorrectly and so on.

If it is Unicom's 2G number, you can open GPRS data Internet traffic. If you are online for more than 6 months, you can also open the provincial traffic package. As the charging and handling methods of GPRS in different regions may be different, you can directly edit any short message from 100 10 to 100 10 with your mobile phone to get relevant handling tips.

If 3G provincial traffic packets need to be activated, you can send corresponding SMS instructions to "100 10" to activate:

1. 10 yuan Package: "KTLL 10" takes effect the following month, and "LJKTLL 10/0" takes effect immediately;

2.20 yuan package: "KTLL20" takes effect the next month, and "LJKTLL20" takes effect immediately;

3.30 yuan package: "KTLL30" takes effect the next month, and "LJKTLL30" takes effect immediately.

If it is Unicom's 3G number, 3G domestic traffic package can be opened after it has been online for more than 6 months.

3G domestic traffic packet service can be handled in the following ways:

1. Log on to the home page of online business hall > self-service > business > package handling > 3G traffic package handling;

2. log in to the mobile client for processing > business processing > 3G traffic packet processing;

3. Send the corresponding SMS instruction to 100 10:

(1) 10 yuan Package: "KT3GLL 10" takes effect the following month, and "LJKT3GLL 10" takes effect immediately;

(2)20 yuan Package: "KT3GLL20" takes effect the following month, and "LJKT3GLL20" takes effect immediately;

(3)30 yuan Package: "KT3GLL30" takes effect the next month, and "LJKT3GLL30" takes effect immediately;

(4) Send "QX3GLL" to unsubscribe.
