No there isn't. But you won't need it to solve your problem. It just depends what your problem is exactly. So the first question is: are you have trouble with memory as in RAM or storage? Phones use the term memory for both inconveniently.
As the phone has 1GB of ram I presume you are mostly concerned with storage. ZTE's pre-installed stuff won't affect that much as their apps are in the system partition and your apps are in data. The main problem on that front will be updates from the play store for system apps you are not using. The easiest solution to that is to uninstall the updates from the play store then go to settings -> apps -> manage apps. Scroll along to the all tab, click the app you don't want and hit disable.
If you want a more permanent solution to removing the apps, then root the phone (which is covered in post one of this thread), install titanium or similar and consult this list for apps you can delete: http://www.modaco.co...p-list-blade-v/
If you still don't have enough data space then it's your user apps that are giving you trouble so consult this post: http://www.modaco.co...blade-v-memory/
If you need more sd card space then consult this post: http://www.modaco.co...ernal-sd-cards/
