The Sims Mobile is a spin-off game from the popular The Sims franchise. However, the main difference is that there are no cheat codes for The Sims Mobile for the first time in The Sims series.
Unlike in previous titles, available on PC and Consoles, there is no in-game console where you could put in some cheat codes like motherlode, which would give you 50 000 Simoleons in The Sims 4.
You will not be able to cheat your way into becoming a Simoleonnaire in The Sims Mobile. This is mostly due to the mobile gaming market and relying on microtransactions. If the game would allow cheats, then the whole system would not work as intended. However, there are many other ways to earn money without using cheats, like completing daily tasks.
Also, make sure to save up on your SimCash with patience. One way to get more money in The Sims Mobile is to be patient and not waste money on speeding up time to complete certain activities.
