Why am I consuming more credits than expected?
A single SMS can contain up to 160 characters. However, due to how SMS works, if you are using some accented characters (like ö, å, etc.) or non-romance characters (Chinese, Hebrew, Arabic, etc.), a single SMS can only contain up to 70 characters.
Most French accented characters fit into the 160 character bucket.
If a message is longer than that, we will need to split the message into multiple SMS, and you will be charged for each one (each additional SMS after the first one for a given message will consume less credits, though).
