How to send a message to the mailbox by mobile phone?

1, simulation, similar to Unicom's short message mail, through the mailbox and mobile phone binding, send short messages, and then processed by the server and sent to POP mailbox. (inconvenient operation and low cost)

2. Mobile phones (smart phones) that support POP mail, after setting up the network, set up a POP account, and then you can send emails to ordinary mailboxes just like using POP mailboxes. The operation is simple, but expensive. Charge by flow. If the monthly flow is unlimited, of course, it is best. )
