How did N 1700 group SMS become MMS?

Samsung's system has this problem. When sending a long short message or sending a group of more than two people, it will automatically switch to MMS mode; Moreover, there are many versions of Samsung ROM, international version/Hong Kong version/China Mobile Bank/China Unicom Bank/China Telecom Bank/Korean version ... Generally, it is cheaper to use long short messages by default (in fact, it is split into several short messages to send) or automatically send MMS when sending a group. China is not in the world, and it is often more expensive after the transfer, so many customization systems have cancelled this "self-defeating" function.

Solution:

1) In the column of SMS-Settings-MMS Settings, there is an option of "Send messages in groups", just uncheck it;

2) Switch to other SMS programs. There are many third-party short messages that are better and more beautiful than Samsung's own, such as ring chat, sliding message, EvolveSMS, hello SMS and so on. And the automatic multimedia messaging function can be cancelled.

1) Brush official optimized ROM or third-party ROM. Basically, Samsung ROM optimized by Great God has been converted to MMS, and native systems such as AOSP and CM have many customized functions of SMS programs, which can also be completed.

I hope this little experience can help you. Happy New Year!
