Hello,
This is what I’ve been doing for about a year.
I have a cell from from work on another carrier. It says, “No SIM restrictions” under Carrier Lock in the About menu.
I have a cell phone on TMobile. It is under contract, about 6 months left, we are making payments on it. So, the phone says “SIM Locked” under “Carrier Lock”.
Both are iPhone 13 Mini. For a long time, I didn’t mind having 2 phones and now it got suddenly annoying. So, I am seriously considering using the work phone to run dual sims for both lines. So, I would get an esim from TMobile and activate it on the other iPhone.
But, one of my concerns is…. will tmobile flag it and charge me for the phone? I don’t plan on getting rid of the TMobile provided phone. I like the tmobile service and I want to keep both numbers. I just don’t want to carry two phones anymore.
