Question

Question about removing cell phone sim

Answer 1

It`s recom mended, to avoid potential troubles

For example, maybe your skin is sensitive and might feel hurt by the electro circuit around it, which doesn`t reach 220V

Maybe somebody calls you and in the verge of changing the SIM, you accidentally throw the phone on the floor. If it was close, you wouldn`t have been distracted
