How to see whether WeChat login SMS is telecom or mobile?

To determine whether the WeChat login SMS is sent by telecom or mobile operator, you can check it by the following steps:

Open the WeChat app and try to log in to the account.

In the login interface, enter your mobile phone number and click Get Verification Code.

Wechat will send a short message to your mobile phone containing the verification code.

Open the SMS application and find the verification code SMS sent by WeChat.

In the short message content, the sender number of the short message is usually displayed.

Check the prefix part of the sender's number, which usually contains the identification information of the operator.

Numbers starting with "106" or "1069" are generally sent by mobile operators.

Numbers beginning with "100" or "1000" are generally sent by telecom operators.

The number beginning with "1066" is generally issued by Unicom operators.

By looking at the prefix of the sender's number, we can preliminarily judge which operator sent the WeChat login message. Please note that there may be some changes in different regions and operators, so it is best to consult the operator you use to obtain accurate information about the specific situation.
