Given SMSs bigger than 160 characters were sent as MMS, I wonder what will be the new UX in the SMS app when I reach the character limit.

Will my SMS be sent into multiple chunks? Will my system tell me it's over the character limit?

>Will my SMS be sent into multiple chunks?

Yes. Actually, it already is. MMS is rarely used now for text-only messages, and instead concatenated messages is the norm. It does require network and OS support on both ends, however.

See https://en.wikipedia.org/wiki/Concatenated_SMS

SMS always had multi-part support (sometimes called "long SMS"), and that's what's used for sending long texts, not MMS.

I thought that long messages were already chunked.

Yes, they are chunked (multi-part) SMSes, not MMSes.
