Canadian High Interest Savings Bank Accounts

Hi everybody, I'm moving next year, leaving my parent's home and will start spending all my savings for food, heating, electricity, etc… And from that point, I will see my savings start go decrease Well that's why I was saving for.

Here's my life style:
-I'm never home, after ending my school classes at 11h30 AM, I'm always at the sport center playing racquetball/squash/tennis or training on my road bike or running on the racing track and then I'm heating on the go at the cafeteria of the sport center and then I'm going at the library to study till 9:00 PM before going home and getting to bed.
-Next year I'm always going to be working at the hospital around 12 hours per day then I'm gonna go at the sport center during the evening so I won't be home again when I'll be in appartment.
-I am NEVER watching TV so I won't have a TV in my appartment, I might have one but I won't have cable. I'll have internet high speed because I only communicate via e-mail. I am ALMOST NEVER talking on the phone. Around 15 minutes or 20 minutes per month, I'm scheduling everything via e-mail with my friends.

So this lead me to asking myself if I'd should go with a permanent phone at my appartment or a cellphone? Of course the cellphone, if cheaper would be the best option.

I currently have no cellphone and I do not have needs for one but if it's cheaper than a permanent phone, I won't refuse to select that option.

I do not know anything about cellphones that's why I'm asking advice from some expert cellphones consumers/sellers that may be around on this site.

My requirements:
-No activation fee
-No network access fee
-No text messages (I have no utility in this)
-No unlimited weekends/evening calls (because I never call anybody but my girlfriend but it happens that I'll be living with her in my appartment)
-No frigging stupid stuff like internet/web messenger/games/music/video (I want a phone that's it, nothing else.)
-Since I'll use about 30 minutes per month, I'd go with a Pay and talk forfait or something like that with activation card on which the unused minutes are valid for the next month and accumulating through the time.
-The cheapest possible

Note: I will not bring the cellphone with me, I'll leave it in the appartment in normal circumstances. I hate to talk on a phone and do not want to be reachable during the daytime. However, it will also be the phone my girlfriend will use. She's pretty much like me, she doesn't want to have one on herself and she speaks around 45 minutes per month.

What would you recommend to me?
(I'll need it for next July)
