Limit is no longer necessary as we are able to send full length text message now with no character limit. This is supported by the majority of carriers.
There may be some exceptions for smaller regional carriers and in those cases the text message will be received 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 160 character default it will be sent in batches of 160 characters.
