Patience.....all too often we are too anxious to wait for a result. When it comes to electronics and water later is always better. At a very minimum you must allow it to dry for 48 hours resisting the urge to turn it on as electricity and water always ends badly. I only recently learned about the dissecant packet hack but rice can be iffy because the small particulate can get in openings like the jack etc...but certain feminine products can be very absorbant or any product with a silicon absorbing gel.
Happy to hear you had success.
Old sim still works . . . I'm surprised (actually shocked), but it's still doing the job.
Please get a new phone and PM sim.
Really .
