Joel Ortiz, a skilled SIM Swapper was caught and arrested back in May 2018. On April 22nd 2019, the District Attorneys Office of Santa Clara County made their formal announcement about his sentence 10 years in prison.

According to the announcement, it only took Ortiz just a few minutes to steal more than $5.2 million in crypto from one Cupertino cryptocurrency entrepreneur. He performed this theft back in May of 2018.
https://www.bitcrypt.co/tech-savvy-student-steals-millions-cryptocurrency/I had to read the article after you said "stole crypto currencies from SIM card". I was like, how the hell does someone steal crypto currencies from SIM card. It's not like you can store your coin in a SIM card! But, then yeah, he used victims SIM card to have access to their account.
Sad people are not aware of security. I wonder where have they saved all these huge amount of coins that could be stole by having access to only their phone number...
