A factory reset of the phone is the way to change device ID normally. Or use an app like Device ID Changer by VTechno

But Wish explicitly states in their user agreement that the discounts are only for first time experience with the merchant.

I have seen some of my referrals pending for a while and never being approved. I guess it is for this reason.

It is better to use some old device or one of your kid's or niece's or grandma's devices to make a one-time big purchase on a new account.

Wishing you luck,
