In the Parameters table, the partsCount section has a typo - "MMaximum".
Same table, in the "from" section, "f specified" should be "If specified"
In the Response section, "IIf your request" should be "If your request"
In the "How to send a single text message" section, "you should set out only" should be "you should set only"
In the "How to send bulk text messages" section, this isn't a typo but I would change the wording "You can also send several messages at once." to "You can also send a message to many recipients simultaneously."
