The text limit is no longer necessary as we are able to send a full-length text message now with no character limit. The majority of carriers support this feature.
However, there may be some exceptions for smaller regional carriers. In those cases, the text message will send in multiple messages. The message will only show the body of the message and will not show the From, To, or Subject line of the message.
If the message exceeds the 160 character default, it will be sent in batches of 160 characters.
