Google Maps GEO Coder Hourly limit

Hi There, I want to show about 700 locations on a Google Map, When I start the encoder I get the error 'Too Many queries'. I am using modeler version 3.3.2. Therefore I cannot use Google Maps Module v2.4. Instead I have to use module v2.1. The documentation of the v2.4 indicates that the hourly limit constraint is removed Questions: Is it absolutely necessary to upgrade to modeler version v4.x.x to get around the hourly limit of the encoder ?
