There has been a lot of recent account hijacking in my industry where I work, specifically in the stealing of money / crypto. This money that is stolen is then used to finance terrorism and other horrific acts that go on around the world each day. This is done by an individual with little to no information about their target (name, address, and simply an email) calling their targets phone companies asking for a SIM card switch. Once the criminal switches the SIM card, they can gain access to all your authentication codes for websites, bank information, and even your Runescape account for recovery.
Unfortunately, telecommunication companies don't have the smartest account reps (most have 1 week of training in India), so your livelihood is basically in their hands. Strongly suggest calling your phone providers, and telling them that you don't want any SIM card swapping on your phone plan, unless you go into one of their stores with valid ID.
Hopefully this is helpful to everyone ?.
