Please rate the level of discomfort you'd experience from not having your cell phone for a week.

None.  I rarely turn it on unless I want to make a call.

Zero.
I once had a cell phone that worked. Dial the mumber and the call goes through.

Then I bought a smartphone and the day after purchace it started "a neccesary update the operating system" Then nothing happened for a couple of days and the there was a charge $100 for the connection time needed to download the 2 gigabyte update. I lost a lot of my faith in smartphones then.

A couple of years after that a family member gave me an androind. I never mangaged to figure it out enough to reliably make a call.

I still have my landline phone and it works. It even have this great feature of blocking 'notifications'. If people want to tell me something they have to pick up their phone and call me. It cute of a lot of spam.

For one week?  Pretty much zero to one.  I'm not a big phone person.  I rarely look at it.  I also rarely look at my emails.  When you spend most of your working life dealing with phone calls, emails, and letters, you have a tendency to tune it all out when you aren't worrying about losing a client.

I never cared much for my phone, I only really use it on my lunch break or if I need to make an emergency call. So not much pain for me. If it was my computers then that would be different, but I managed to go without them for the week I had no electricity. I mostly just sat outside watching the lizards scamper about. They must have had a baby boom or something, they're everywhere.

I'd be on the moderate-severe level. I use my phone to stay in contact with much of my family since I don't live close. Most of the people I'm closest to in life have their cell phones as their only means of communication unless I see them in person... which wouldn't happen unless we communicate first. HA. I also do a lot of work on my phone. 

I don't love this, though. :/
