Now a day, having your own mobile phone would be essential.
Some months ago, the Japanese president and the government assessed several mobile companies' pricing. The result was it is too high. Personally, I was wondering by today why Japan's price is more expensive than the UK's.
So, the next week, a new service with new pricing will start at the mobile company I may choose. (All of each Japanese mobile company has released new pricing.) It becomes a lower price.
I will get the new one. But have not decided yet on iPhone or the others.
I am looking forward to getting in contact with new people by the brand-new mobile.
