Is there a charge for wireless Internet SMS authentication?

Sending CXGPRS to 10086 is completely free. There is a gprs consumption record on the call record on your mobile phone. You can check the traffic you used last time and the total usage this month (first, clear the record when you don't use it at the beginning of the month). If you want to see the detailed records of your own traffic, you can log in to Monternet. Enter the business hall. Detailed list of Gprs this month. You can check the gprs usage so far this month. Very convenient.
