How to return traffic by sending SMS with Unicom card?

If you are Unicom's 2G package number, you can open GPRS and 3G provincial traffic packages. As the charging and handling methods of GPRS in different regions may be different, you can directly edit any short messages such as 100 10 to 100 10 with your mobile phone to get relevant cancellation tips. If you need to cancel the 3G provincial traffic package, you can edit the SMS "QXLL" to 100 10 to cancel it, which will take effect the next month.

If your number is Unicom's 3G package number, you can open a 3G domestic traffic package. You can edit the short message "QX3GLL" to 100 10 to cancel, and it will take effect the next month.
