Hello @Saumya1904 ,
I believe your question may be regarding The Sims Mobile game and not SimCity BuildIt.
You may want to visit The Sims Mobile "Be social and grow relationships" thread, https://answers.ea.com/t5/General-Discussion-Feedback/Guide-Be-social-and-grow-relationships-in-The-... ,
or the Sims Mobile Code Sharing thread. https://answers.ea.com/t5/General-Discussion-Feedback/Wanted-Friends-Friend-codes-sharing-thread/m-p... .
You are currently visiting SimCity Build It support, a different game's message board.
If this or any other information shared is helpful, please use the "problem solved" button or grant XP.
