Telecom mobile phone card forgot the number, how to inquire?

Hello, you can check the number in the following ways:

1. The mobile phone card is in use and can be used normally. You can get your own number by calling the mobile phone with caller ID nearby.

2. If the mobile phone card can't make a call when it is down, you can take the card to the telecom business hall and check the corresponding mobile phone number through the iccid on the back of the card.

I lost my mobile phone card. I took my ID card to the nearby telecom business hall to check my telecom mobile phone number.
