Ring tones per sim

You can set a ringtone or text tone for a specific person. In the Contacts app, find and tap the person's name, then tap Edit in the upper-right corner. Tap Ringtone or Text Tone, then choose a new sound.

You're welcome. Since only cellular data (phone number) is stored on a sim on iPhone, you would not be able to set different tones by the sim itself. But I'm glad you've at least got different tones now set up for your contacts.

The sim likely won't effect this. As long as the contacts remain the same.
