I've lived most of my adult life without a telephone. When i had employers who insisted that i be "reachable," i've always made them provide me a pager if they insisted. Later, i had employers who provided a cell phone, with the proviso that i pay for personal calls. So, i never gave out my cell number, or only gave it out to a select few. Later, i got a cell phone on a pay as you go basis, with no roaming charges, and no charge for incoming.
To me, it was always a blessed relief not to have had a phone, the more so as i saw how other people were tied and bound by their phones. I'm sure you'll have no problem with this.
