What is GSM 7?

GSM-7 is a telecommunications coding standard that uses 7 bits instead of the normal 8 bits. This enables SMS messages to consist of up to 160 characters. If there are no special characters in the message, and the underlying carrier’s system enables this, the recipient will receive a single message with the multiple parts of the message properly arranged in the correct order.

If 160 characters are not enough for the message that you need to send, MessageWhiz’s smart messaging system will ensure that your message still reaches the intended recipient. The long message will be divided into multiple parts, but still delivered in the correct order. These are called concatenated messages which can result in charges for each of the component messages.
