As you might know, there are three cell phone network providers here in China. 1.China Mobile 中国移动 (0.7 billion subscribers) 2.China Unicom 中国联通 3.China Telecom 中国电信 Some cell phone suppliers like APPLE would like to work with these network providers to increase their market share. 电信版 just means that your cell phone can be used with China Telecom network, you might not be able to use it with other services providers.

The phone can only read 180, 181, 189, 133, 153, cellphone chips

In china, some software can found both in handset or PC format. such as QQ, kugou, baidu. so, distinct between them, software are label as 电脑版， 手机版。

ありがとう！

"电信版"の携帯を買って、 ”电信”のユーザーになります。その携帯の価格は安いかもしれないけど、”电信”会社のサービスを受けなければならない。他の選択は　無理です。契約するから。
