Review: Coolpad Revvl Plus for T-Mobile

I have tried to download a different style font than what this phone comes with and I find that it does not allow the download to connect to the system. Am I doing something wrong or is their something I am "NOT" doing to make this happen. Can someone tell me how to do this so I change the "font style" that is on this phone God it is soooooooo boring to look at the style it comes with. Thanks for the help !!!
