There are SMS messages, which can contain about 160 characters. Japanese uses multi-byte encodings, so the actual character count is much lower. Also, people like to send pictures taken with the built-in cameras, music and other things which don’t fit well into 160 byte limit.
Therefore, MMS (multimedia messaging service) was born. It works like this: you get a short SMS message using SMS protocol, and then your phone has to use data connection to receive the rest of the message from the server. SMS messages work everywhere, but ways and protocols for retrieving the actual message are different from one provider to another. If these protocols are not followed, only “subject” line of MMS message will get through, which is actually delivered via usual SMS.
This is why we need specially tailored application to receive MMS messages on softbank, another specially tailored app to receive MMS messages on DoCoMo and so on. Also, this is the reason, why originally iPhone did not support MMS (it was added about a year later) and why HTC Desire still (oficially) does not support MMS, however there are a few versions of custom-made software, which, more or less, aleviate this problem.
