How do I know whether my mobile phone uses the traffic in or out of the province?

Method 1: Customer service telephone inquiry method

1, call the operator's customer service number, and the telecom number is 10000.

2, according to voice prompts or manual services, consult your mobile phone charges, and network charges can of course also query traffic.

3. By the way, popularize common sense: mobile customer service is 10086.

Unicom's customer service is 100 10.

Telecom customer service is 10000.

Method 2: SMS query method

1. Send the corresponding instruction code "42 1" (that is, mobile Internet traffic packet) to 1000 1.

2. Wait for the corresponding text message to reply to your mobile phone.

3. Go and have a look.
