Unicom's mobile phone traffic is noisy to 540 megabytes. What if there is no SMS reminder?

You can handle the traffic SMS reminder function in the following ways:

Activate 3G traffic SMS reminder: Send SMS command KTTX to 100 10 to activate the weekly reminder service of mobile Internet traffic.

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