This doesnt look like a sim swap yet- unless your iphone is auto-forwarding texts to your imessage.
You are under attack from a hacker, you will need to start taking action now. But first take a deep breath and move forward one step at a time. Do not rush, but do not delay.
What you want to do is re-establish "root" access to all your accounts and services. Start with the most important and work backwards to the least.
*PHONE NUMBER*
SIM Swap defense:
First call your cell phone provider. make sure they are aware that someone might be trying to steal your infomation and request that they notify you on a different phone number (a family phone or landline) before authorizing a sim card recovery.
*Ask them if they have any suggestions for help with identity theft protection. *
IPHONE USER- APPLE ID
Apple security:
on your iphone search "lockdown mode" and turn it on.
This adds a protection level to your device and accounts. follow any instructions on attempted password resets and make sure you reach the point of *changing your main Apple ID password.*
EMAIL
*Google-Gmail, or Microsoft accounts:
Remember to work one step at a time. Do not rush, but do not delay.
Log in to your main email first from your main device (your phone)
See if you can change the password.
Double check the 2fa settings, and optionally upgrade the 2fa from your phone number to a 2fa app with the revolving 6-digit codes. Such as Google Authenticator, Microsoft, or third party option "2FAS Auth"
-using these apps for 2fa is superior and will protect your accounts in case the attacker gets access to your phone number.
*MONITOR YOUR ACCOUNTS CLOSELY FOR THE NEXT FEW WEEKS AND CONSIDER CHANGING YOUR EMAIL AND POSSIBLY EVEN GET A NEW PHONE NUMBER*
I will do this today. Thank you so much
