Can I send short messages to my mobile phone? If not, then if there are details of the fax machine on the mobile phone, go in and have a look.

The mobile phone can send short messages to the mobile phone, but the mobile phone must support the short message function (if the other party's mobile phone doesn't support it, the short message will still be sent, wasting a dime, but the other party can't see the short message, which is useless). Of course, the area code has to be added. This "-"means to distinguish the telephone number from the area code. Just send it directly without adding it. For example, sending it to 035 1-43776658 means sending it to 035 143776658. This area code must be added, otherwise it will be sent to the number 43776658 in your city. For example, it is sent directly to 43776658 in Beijing, which is equivalent to 0 10-43776658.
