How to send short messages directly from the network to the mobile phone?

MSN is also ok, you just need to add his mobile phone number to your contacts. When finished, the contact's status changes to "Mobile". In the future, if he is not online, you can also send him a message and send a text message directly to your mobile phone.

You can also create a new contact, instead of writing an email address, just write your mobile phone number, and then you will keep texting him.
