What is the format of EMS?

Some netizens often ask what EMS messages are. What can this EMS message do? Let me answer briefly here: EMS, also called enhanced short message, can send simple pictures and sounds in addition to ordinary short messages. Based on ordinary network, the charging method is similar to ordinary SMS, and is generally calculated according to the number of bytes sent. In general, sending an EMS containing a simple picture is charged according to 2 ~ 3 ordinary short messages.

So can we replace the ringtone in EMS with other pictures and ringtones to send MMS? Do the following experiments:

1. Use UltraEdit to find free addresses.

2. Use SAMSUNG-DIY as the offset address, and at the same time make the ringtone (be careful not to write the wrong address).

3. Brush these files in with OptiFlash.

In "Write Message-Options-Add Item-Ring Tone", you can hear the ring tone you just brushed in. You can write a short message (plus the ringtone you just brushed in), save it, send it to yourself and listen. You heard the modified ringtone, but you can't save it. It can be sent to Samsung X 108 (software version L3) and S308 through GSM and GPRS. In short, the experiment was unsuccessful.

I compared the built-in EMS ringtones of A6, A8 and A2, and they are all the same, except that the "click" in A2 is called "Tada" in A6, and there is no difference at all. Compared with X 108, the built-in bell is the same, but the storage position is different.

What is this EMS bell space for? ? Personally, I feel that the bell ringing in EMS can't work. The so-called EMS message just loads a pointer to a ringtone or a picture. When sending EMS, I send this pointer out. When the other party receives the short message and opens it, activate the pointer to bring up the ringtone. We only save the hands when we save these bells, so it is impossible to receive the bells we don't have. If so, "SMS-My Content" also contains pointers, so why do you need this function? It's a waste of space and a waste of mobile phone control panel! Even if you modify the pointer ringtone in your mobile phone to achieve the purpose of sending, the other party will not be able to play it because the pointer cannot be found after receiving it.

To tell the truth, I'm getting more and more confused now. I really don't know what this function is for. I hope someone can give me some advice. I appreciate it!
