SMS on company SIM card in my personal android phone

[AC Question]

Hello Android friends,

I have a specific situation for which I have not been able to find any answers...

I have a phone SIM card from my employer and I use it mainly to make phone calls.

I put it on my private phone, but I did not installed any company software on it (to acess work emails for example)

My question is : can my employer read SMSs sent with company SIM or listen to phone calls? In theory, they have no access to my phone.

Do they have access to data stored on the SIM ? At telco level? Would they monitor that in any way?

Thank you.

Welcome. There are a few ways to catalogue at least your calls and texts.

Apps can be hidden on the work phone, afaik.
Texts can then be synced to and read from the account the work phone is under while using that phone, but if your own phone is on a different account I don't think your texts can be read.
I welcome other views.

There is nothing stored on the actual sim card (some sim cards were used to store basic and limited Contacts information as a legacy of 2G phones).

Your employer will obviously have access to the phone account with a list of calls / texts and to which numbers.

This is a great answer. As someone who sets up company phones there's nothing that you can get off the sim card. However tracking phone calls is very easy and the above user is correct you can hide IT management apps to do additional tracking. If if the option is available I would recommend taking a company device and then keeping your personal cell phone personal.

If the company hasn't had physical access to your phone (to install apps), there's nothing they can do unless a court of competent jurisdiction issues an order for all texts and/or calls made by and to that number. (The number you're using when using the company's SIM is the company's number.) they still can't tell what was on the texts, just that you sent them (or received them). But any police department can do that. Getting the actual content of calls or texts is wiretapping (whether it's done in real-time or at some later time) and that requires a court order. (In the US, at least. If you're in another country, check with an attorney in your country.)
