How to check the mobile running card number of postal Fengxin?

At present, both China Mobile and China Unicom have launched mobile cards specially used for surfing the Internet. If you want to check the number of the mobile card, you can call the service number of the operator. The mobile number is 10086, and the Unicom number is 100 10. If the flow card can't make a phone call, then pay attention to the official WeChat account, and bind your flow card to the official WeChat account, and you can enter the original menu to check the flow card number.

Traffic packets are divided into traffic packets and annual packets. The validity period of the flow card is 1 month, and it is 1 month from the time of purchase. When it expires, it will be stopped. The annual package can accumulate package traffic, and the total traffic will stop immediately. When the validity period expires, it will be turned off, and the remaining flow will be invalid. After the renewal, the new package will be calculated again.
