On Friday afternoon, January 4th

I received a mail from the cell phone company that canceled my contract last month today.

I opened the envelope and took the paper from it/out.

The paper is was not a demand notice but a 'Reminder of lost or stolen cell phone.'

How did the police know my ID? Perhaps by ICCID/IMEI.

My iPhone that was lost last month was found in Osaka although I don't know whether it still works or not.

According to the paper I have to pick it up by myself, so I can't ask my friend.

I can't afford to pick it up from Nagoya now especially I think what if it already doesn't work?

So, I'm going to pick it up when I will have my next an interview or there is something important appointment in Osaka.

It was just as well that I already cut the contract off with the cell phone company.

If only my coat which was lost at the same time is was found.

On Friday afternoon, January 4th

１月４日金曜日の午後に。

I received mail from the cell phone company that canceled my contract last month today. 
先月解約した携帯電話会社からの手紙を今日受け取った。
I opened the envelope and took the paper out.

封筒を開け、紙を取り出した。 
The paper was not a demand notice but a 'Reminder of lost or stolen cell phone.'
その紙は督促状ではなく、『携帯電話機拾得のご案内』だった。
How did the police know my ID? Perhaps by ICCID/IMEI. 
どうやって警察は僕のIDを知ったのだろう？たぶん製造番号でかな。
My iPhone that was lost last month was found in Osaka although I don't know whether it still works or not. 
先月失ったアイフォンは、大阪で見つけられた、まだ動くかどうか分からないけれど。
According to the paper I have to pick it up myself, so I can't ask my friend who lives in Osaka. 
その紙によると、自分自身で取りに行かなければならないので、大阪の友達に頼むことは出来ない。
I can't afford to pick it up from Nagoya now especially I think what if it already doesn't work?

名古屋からそれを受け取りに行く余裕は今はない、特にすでに動かなかったらどうしよう？って考えると。 
So, I'm going to pick it up when I have my next interview or there is some important appointment in Osaka. 
だから、次の面接か、何か重要な約束が大阪である時にそれを受け取りに行くことにしよう。
It was just as well that I already cut the contract off with the cell phone company. 
すでに携帯電話の契約を解除しておいて良かった。
If only my coat which was lost at the same time was found.

同時に失ったコートも見つけられていれば良いのだけれど。
