this is the money cheat i use:
1 Open sims freeplay
2 Get all of you sims at one house
3 Have all your sims plant your most expensive seed ( i use beans )
4 Click home button
5 Double click home button, tap and hold on sims free play app until read minus icon appears and press it
6 Go to settings and turn on airplane mode
7 Go to general and tap date and time
8 Change month to one month later, for example, if the date was March 14, then you would change it to April 14, DO NOT CHANGE THE YEAR
9 Go back to sims free play app
10 When it says cannot connect, DO NOT press retry
11 Go back to settings and turn on wifi DO NOT, WHATEVER WHAT YOU DO, TURN OFF AIRPLANE MODE EVER
12 Go back to sims free play it will go back to your game by itself do not press retry just leave it be
