Topic: Lost Nintendo Switch : Person changed name from "Michael" to "Micahfound" there's hope.

Okay, so I'm a dummy and put my nintendo switch on my car trunk as I drove off from my girlfriend's. She logged into hers today and saw on her friend's list that they changed my name from "Michael" to "Michafound" so that seems like they're trying to communicate. We thought about changing her name to her phone number in hopes that they call it. But switch only allows 5 digits to be numerical characters, and a maximum of 10 characters total. At the moment my other friends (of which I have like 2) changed their names to "ACNH mail" and my GF is logging into Animal Crossing and sending them mail with her phone number in the body. Are there any other ways to communicate with friends on the switch? Sigh. Any ideas are appreciated.

@danieljay You can put your twitter username or discord username ir make a smaller phone number for them to call on like 20934 , hope you find it.
