Looking for WeChat, I can't send SMS zc42.

The message zc42 cannot be sent back to WeChat for the following reasons.

1, SMS can't be sent out, and a very common reason is that the mobile phone is in arrears. It's normal that you can't send text messages because your mobile phone is in arrears. If this is the case, you can call the operator's customer service phone to check the phone bill balance.

2. When sending a short message, the prompt fails. Not everyone's text messages can't be sent out, but a few people's text messages can't be sent out. Therefore, it is necessary to check whether the phone number is wrongly operated and dragged into the blacklist.

3. The smart signal on the mobile phone will show the strength of the signal. If it appears in the signal shielding area, it is normal not to send text messages.
