Message Length3Typical SMS length is 160 characters in most countries. However, countries like Canada only supports messages up to 136 characters in length. So, if your SMS provider doesn’t automatically split your long message into multi- part messages, according to each wireless operator’s rules, the wireless operator will reject and fail the message.

If your SMS provider doesn’t automatically split long messages into multiple messages, ask them to implement a solution.
