What does it mean to inquire about roaming places?

Roaming place query service can query the places where the owner himself has been in the past 30 days (accurate to prefecture-level cities).

The specific query method is similar. Generally speaking, the last four digits of the ID number of CXMYD# are the customer numbers that are compiled and sent to major operators. After authorization, the system will feed back users' national/global roaming information SMS queries in recent 15 days and 30 days.

1. Mobile users, edit the short message content: "CXMYD" (roaming initials) to 10086. After receiving the verification message, reply to the last four digits of the ID number registered by the mobile phone number, and you can query the visiting place within 30 days.

2. Unicom users, edit the short message content: "CXMYD# the last four corresponding certificates of this mobile phone number" to 100 10, and you can get the cities that this number has passed in the last 30 days.

3. Telecom users, edit the short message content: "The last four digits of CXMYD# ID number are to 1000 1". After receiving the authorization prompt, users can check the roaming places in the past 15 days after confirmation.
