Large SIM card does not work and I think you could turn off the BT. However, one should not have high expectations of the device. It's cheap plastic and the voice quality is subterranean compared to Nokia models from 20 years ago. At the time, I wanted a device that was as simple as possible ... but not at the price of non-existent quality in every area.
Nothing against Digitec, they were very obliging back then. But in my opinion, the name Nokia no longer stands for anything.
