All OS Do you carry a separate work and personal phone?

Yes, also using Samsung Private Folder / Knox based isolation. Phone is mine, 1 sim company's which is open when screen is unlocked, other is personal sim in secure folder together with personal apps requiring more security.
My One private number used only for banking and transactions is always disabled.
Using that only when required to make any kind of payment or check accounts or other financial apps for otp etc.
 
I have an iPhone and an Android. It started off as a work phone and a personal phone but at this point, I use social media and reddit on my iPhone and work, quick commerce, and whatsapp on my Android.
 
Isn't this rule enforced by companies rather than you deciding to carry two devices?

Some devices can't be used on company's network, so they provide you with one. Some do it for the sake of consistency and ease of operations. Some companies want to maintain their image so they give you an iPhone. And then there are projects that don't allow any kind of external devices.

I was lucky enough to not have any kind of restrictions. I was required to be available on call during cortical times only.

What's the point of disabling it?

1) you won't get real time SMS notifications if someone is trying to gain access to your account
2) what if your bank is sending you an update... of a planned downtime?
3) there's no extra security if your phone gets stolen along with that disabled SIM

Not in my company. They expect me to be available in my phone all the time so I have found it as an excuse to use another number as per my convenience. Also, I use Android + iPhone both for their own use cases. I have an air tag & apple watch that needs iPhone to function well.
 
I have only one Android phone, and use it for both personal and office communication. Earlier i had configured office email and chat on phone, but later discontinued as it was becoming too much of distraction.

1. This hardly happens, if you know basic dos and donts.
2. I dont care about a banks planned downtime.. I got few more handy (both debit and credit)
3. Security is nowhere even if both your handsets get stolen.
My PassWord manager, with 2fa and other layers works best till day.
 
If you work in support or in higher management, chances are you will be given a dedicated work phone to reach aka catch you round the clock and you have no escape even during official holidays and vacations or honeymoon even in the middle of the act they want you to perform for them primarily. A work phone makes you a legal slave of an employer and the only escape is to escalate or look for an opportunity outside.
 
But what are you trying to achieve by keeping that SIM disabled? Is this some obscure industry secret?
Nothing as such, no secrets etc.
I am now habitual, to enable SIM every time to make a UPI transaction (or anything else) and disable immediately after done.
When any other person gets access to phone, it takes time for them to understand why the payment with SIM1 is getting declined or no OTP received.

My own small security setup..
