How to calibrate Expo Pass by SMS?

Every time the SIM card is removed from the mobile phone and then put into the mobile phone, it needs to be calibrated.

After you put it in your mobile phone, the SIM card of your mobile phone will send a text message, and you will receive a calibration text message later.

1. If your mobile phone model can be displayed in the short message, such as "Your mobile phone model is-xxxx".

You can directly reply to any short message (whether Chinese characters or letters), and you can use it after opening the card swiping function.

Or you can choose to go to the business hall to open the card swiping function through the calibrator.

2. If your mobile phone model cannot be displayed in the SMS.

Because your mobile phone model is not in the system at present, you can't reply to SMS and directly open the credit card function.

You need to go to the business hall and turn on the card swiping function through the calibrator equipment before you can use it.

Suggest the contact information and address of Shanghai Mobile Business Hall. You can consult 10086 for confirmation.
