About my keitai

I use 'willcom' for my keitai. The good point of willcom is the payment rates. It's very cheap. Of course the function is better willcom than smart phone. However my requests for keitai are phone and email. willcom is no problem about them. I think smart phone is so good and convenience in my life, but it's ultimately said that they don't need in the keitai's function during student. If I become a worker, I would buy smart phone and pay myself.
Now, keitai becomes like our part of body. Some people have two or more keitai. It can't be concider 10 years ago. The age pass so fast.(109/3041)
