Why can't the mobile email be sent out?

The reason why mobile email can't be sent out:

1, the mailbox seems to use the access mode of CMNET, instead of the usual CMwap access mode of WAP network, so in the information function-Settings-SMS of the mobile phone, there is a mailbox gateway that needs to be set.

The specific settings may vary from place to place and from person to person. It is recommended to take them to the local customer service, which is provided by the service set by the mobile phone, free of charge during the warranty period.

2. Secondly, it is necessary to ensure that it can be distributed in the case of networking.

3. Only by entering the correct email address of the other party can the sending be successful, otherwise it will not be successful.
