WARNING! My iphone was hijacked. They stole my email, my tmobile account online, and my coinbase account,

Perhaps I was naive. My first venture into crypto currency. And I lost all the coins! I found that I could not send or receive phone calls on Dec 3, 2021 afternoon. Which came first? The chicken or the egg?

• the crooks took over my yahoo email; 
• they took over my Tmobile online account and “cloned” my iphone;
• they took over my Coinbase. 

Because my iphone was "cloned", all the messages (warning of password change, or verification codes) went to the crooks who quickly changed my passwords on Tmobile and Yahoo mail, and changed password and device on Coinbase. All in about 35 minutes, it seems.

I did call T-Mobile on Dec 3, 2021 to fix my hijacked Tmobile online account and get my iPhone "back". The tech said that I had an old sim chip which allowed the phone to be vulnerable to be hijacked, and able to be put on the crook's phone. So I removed the sim, and the tech reset to the internal sim.

I got all my accounts back. It took hours in 2 days. I changed all my passwords. But all my bitcoin was gone. Coinbase takes no responsibility, but will assist in a police investigation. Tmobile told me about the old sim chip vulnerability. When I bought my iphone 12 in Feb 2021, they never mentioned the vulnerability of the old sim chip. I didn't even need the old sim chip apparently. But I used it to transfer the phone data. I should have removed the sim chip at that time after transferring the data.
