In The Sims Mobile, like in any Free to Play production, you will come across some advertisements. They give random prizes - coupons, cupcakes or money. The ads do not appear independently of the player. You will only get a proposal to see ads after finishing an event or you can start watching ads on your own initiative with the help of mailboxes.
The ads do not cause much of a problem. If you click on one, you do not have to worry about accidentally downloading or buying something. After each finished advertisement, you can simply turn the ads off and return to the game.
If watching a 30-second ad is not a problem for you, you should watch them as often as possible. This will allow you to get a lot of useful items that will make the gameplay much simpler.
Ads from mailboxes
Ads from mailboxes appear every several dozen minutes. There is no way to constantly watch ads and collect items. They disappear if we do not collect them for a long time. Mailboxes can be found in several locations within the city as well as in front of your home.
Ads after events
After some events, usually related to work, you will receive a proposal to see an ad. The game will immediately show you the items you will gain. Usually, it is a larger amount of simoleons and a coupon for your home.
