Is there a charge for mobile phone traffic reminder SMS? I am a mobile phone.

Hello, there is no charge for the mobile phone traffic reminder function.

You can activate the traffic reminder function in the following ways:

1, activate 3G traffic SMS reminder: send SMS command KTTX to 100 10 to activate the weekly reminder service of mobile Internet traffic.

2.2G traffic activation SMS reminder: send SMS 520 1 or 2GKTTX to 100 10 to activate the traffic SMS reminder service. By default, it will be reminded once a week. From 9: 00 am every Monday, the system will automatically send a traffic SMS reminder, and you will receive a SMS reminder after the successful opening.

3. If you need to set it as a daily traffic reminder, you can try to send ATTX to 100 10 for processing. If you can't handle it, I suggest you consult Unicom's manual customer service to understand the relevant handling methods.

4.4G Postpaid System automatically sets daily reminder.
