DiL works from home and has an old phone which she uses for keeping in touch with clients. She turns it off at six o'clock in the evening and then on again the next morning. This because some of her clients live OS and like constant updates. She makes things.
The phone is on its way out and she wondered if it's possible to have two numbers one one phone, rather than buy another one for work purposes. And if it is, could she turn it off like she does now?
TIA
