I have a cheat of having more simolions and inspiring a sim.
1st-go to the sims freeplay app then press the home button.
2nd-Go to settings find the General and press it,once your there scroll up until you the Date and Time.Set the "Set automaticaly" off,then change the year to 1970 (Years only).
3rd-Once you finished to set the year double click the home when you see the multi-tasking bar hold the sims freeplay until you see the minus sign.
4th-After clicking the minus sign click home,then go to the sims freeplay app,wait to loading,after it loads don't touch anything.
5th-Press the home button and go to settings again and set the "Set automaticaly" on and go back to the sims freeplay app and you have 5,000 or less than or more cash.
Thanks,I wish it could work to you.
Things u may know if you don't know what.
Multi-tasking bar-when you double click the home button it open.
Minus sign-it will come out if you hold any app in the multi-tasking bar,but don't worry your game would not delete.
