Sending format of SMS

Only information in text format can be received and viewed by the other party on the mobile phone in the form of text messages!

The fax format is to use a mobile phone to send a fax and send it to the other party's fax machine. It is not possible yet, but I heard that it will be possible soon!

E-mail means using a mobile phone to receive and send E-MAIL

I don’t know much about paging!

So if you are sending and receiving short messages, you can only choose text format. If you choose other formats, the sending will be unsuccessful, or the recipient will see garbled characters
