Just received a short message, "Enable mobile data traffic function". Is there a monthly fee for this function?

Hello, there is no charge for opening this function, but there is a charge for using this function to surf the Internet, just like there is no charge for opening the SMS function, but there is a charge for sending SMS, so you need to make a choice now, whether to turn off the data traffic function or apply for a monthly subscription. If you don't need to use your mobile phone to surf the Internet at all, then turn off this function. If you need to receive MMS or download things online, you'd better turn on GPRS traffic monthly. These can be solved by calling customer service.

After opening it, if you don't want to use it, just turn off the GPRS function and there will be no charge.
