At times, I’ve done the two phone thing, and honestly it’s a pain. Phones take up pocket space, and you need to keep both charged which is another hassle. Ultimately, I decided on just using one phone (physical SIM for one number and eSIM for the other number). With android at least you can adjust your preferences on the fly (switching between the 2 numbers for texts, voice, data while always being able to receive calls/texts on both). It’s not without hiccups, though, especially if you travel internationally and the two SIMs vary in terms of data/text privileges
I get what you’re saying — but my plan is to never leave the house with that second phone. It will be used only at home for remote work purposes.
