Re: My Sims smartphone won't stop ringing

@poppingmythik  It probably is the KW mod, or at least that mod is contributing to the problem.  It can introduce corruption and other problems as the save progresses, so seeing an issue surface after a while is not surprising.  This mod almost always destroys saves sooner or later; the only question is how long that takes to happen.

At any rate, you could try evicting your sim and placing them back in Edit Town mode.  This will preserve their job and relationship but remove their promised wishes and opportunities.  Try this on a copy of your save so the original remains intact as a backup should you need it.
